       BACKGROUND  
       [0004]     The present invention relates to a materials cutting device. More particularly, a wood cutting device used in the capacity of a shaper or saw. The device performs numerous types of cuts, such as chop cuts, miter cuts, crosscuts and rip cuts, both from above and below the work piece support table.  
         [0005]     Various saws currently available are used for performing a variety of operations and several saws combine certain functions. See U.S. Pat. Nos. 5,797,307; 5,768,967; 4,211,134 and 3,465,793. However, in the various permutations, there appears to be a fixed relationship between the cutting blade and the work surface or table or the cutting blade is designed to move primarily relative to the fixed position of the work surface. There is presently no saw known in which the position of the work surface, and consequently, the work piece, and the cutting device can adopt many and varied positions relative to one another. This results in much of the prior art being utilized for limited functions such as cutting as opposed to routing, or chop cutting as opposed to rip cutting. Portability functions are not integral in much of the prior art.  
         [0006]     Currently existing saws uniformly exhibit narrow cutter enclosures or inserts. Because of this limitation, these saws are less capable of performing cuts on irregularly shaped work pieces. Cutter inserts are non adjustable and when changing cutters, inserts must also be changed or removed. Adjustments in blade angle and height in the prior art is usually accomplished by a sometimes laborious and time-consuming hand cranking. In those existing saws where the motor is close to the cutter, moving the cutter also requires moving a bulky motor past the work piece.  
       OBJECTS AND ADVANTAGES  
       [0007]     An object of this invention is to provide multiple cutting functions and complete versatility regarding the way the cutter can act upon a workpiece and complete versatility regarding the angle the workpiece can adopt, through the adjustability of the machine, in relation to the cutter. Because of its mobile, yet substantial base and carriage, the benefits of many different cutting functions may be easily transported to the job site yet have the stability of the stationary machines seen in a standard workshop. The device is stable on its own frame without the necessity of a separate work platform.  
         [0008]     Another objective of the present invention is to provide a broad range of configurations of the work surface and the cutting apparatus relative to one another. Just as the cutter may be positioned above or below the work surface and consequently above or below the work piece, the work surface is also adjustable and may be raised either lower or higher in relationship to the cutter. In addition, the work surface may be tilted from the horizontal resulting in miter cuts of varying degrees being performed on the work piece. The cutter arm and consequently the cutter may be moved back and forth in relation to the work surface and, in addition, is rotatable through 360 degrees along its long axis. This coupled with the fact the work surface may also be tilted, results in a miter cuts through a large range of angles. Thus, this device allows an unlimited number of positional permutations to be achieved.  
         [0009]     The miter gauge and the variable opening between the left and right work surface components allow the work piece to be placed and supported in large number of positions. A corollary to the ability to place the work piece in a number of positions is the ability for the invention to accommodate work pieces with a large variety of shapes. Because of this feature, the device has application in a production settings where it might be more efficient to pre-assemble components and then subject the component to certain milling operations. The pre-assembled components could have irregular shapes this device could accommodate. The distance between the left and right work surfaces have an added advantage of accommodating cutters of various sizes and configurations.  
         [0010]     The cutter can also be rotated to and fixed in a position parallel to the worktable allowing the work piece to be laid flat on the work surface. This would allow the routing or cutting of the edges of the work piece. The cutting arm can be moved downward into the work piece facilitating a chop cut. The arm, if kept on the horizontal, can be moved through the work piece by riding forward and backward on rails allowing the blade to move horizontally through the workpiece for cross cuts. The table elevation assembly associated with the work surface is also capable of adjusting its position relative to the work piece from both above and below allowing a depth of cut adjustment. The broad range of adjustability of the device components along with the ability to position the work piece in a number of ways provides maximum flexibility and utility.  
         [0011]     In addition to the adjustability of the device, another object of the invention is to allow the operation and adjustments quickly, safely and efficiently from a front-mounted control handle. Table tilt and height are controlled though mechanisms that initially allow quick adjustment without hand cranking. However, after the quick adjustment, this device allows hand cranking to achieve more precise settings if needed. These quick adjust mechanisms utilize threaded drives which benefit from a mechanism to both lubricate and clean the threads of dust and debris as adjustments are made thereby avoiding wear and extending the life of the adjustment components.  
         [0012]     Utilization of a direct shaft drive connecting the motor to the cutter allows better power transfer, requires less space than standard belt drives and dramatically reduces vibration associated with belt drive mechanisms. Further, using a shaft allows the motor to be positioned along the same axis of the shaft itself avoiding using additional gears. Using a shaft with the motor position along its axis also allows the shaft to be rotated 360 degrees allowing the cutter to adopt almost any orientation relative to the work piece.  
         [0013]     The combination rip face and miter gauge is integral in maintaining work piece positioning yet allowing a variety of work piece positions to be achieved.  
         [0014]     These and other objects of the invention will be apparent to those skilled in is art from the following detailed description of the preferred embodiment of the invention.

     DETAILED DESCRIPTION OF INVENTION  
       [0072]     Turning first to  FIG. 1A , the relationship of the various components of the cutting workstation are seen. The cutting work station is composed primarily of metal.  FIG. 1B  illustrates the mobile base assembly which allows the cutting workstation to be mounted thereon.  FIG. 1C  illustrates leg assembly  13 . Leg assembly  13  is composed of axial component  13   b , vertical leg struts  13   e , which are connected in turn to base leg component  13   g . The ends of base leg component  13   g  end in friction feet  10 . Leg assembly  13  is pivotally mounted to second leg mounting strut  17  and first leg mounting strut  17   a . Second leg mounting strut  17  exhibits second leg mounting plate  13   d , which further exhibit second leg mounting plate detent  13   f . Similarly, first leg mounting strut  17   a  exhibits first leg mounting plate  13   a  which also in turn exhibits first leg mounting plate detent  13   c . The ends of axial component  13   b  are disposed within the second leg mounting plate detent  13   f  and the first leg mounting plate detent  13   c  allowing the entire leg assembly  13  to pivot there within. First leg mounting strut  17   a  is mounted to upper frame second longitudinal member  19   d  while second leg mounting strut  17  is mounted to upper frame first longitudinal member  19   c .  FIG. 1D  illustrates the cutter arm assembly  249  which carries the power source, power transmission means to the cutter and the cutter itself is contained. Cutter arm assembly  249  is mounted to cutter arm positioning assembly  251  which is illustrated in  FIG. 1G . Cutter arm positioning assembly  251  allows the cutter arm assembly  249  to be raised, lowered, moved forward and rearward, and moved in a chopping action. Cutter arm positioning assembly  251  along with cutter arm assembly  249  is mounted to workstation base frame  253   a  which is illustrated in  FIG. 1H . The cutter arm positioning assembly  251  is moved forward and rearward, along the workstation base frame  253   a .  FIG. 1F  illustrates worksurface positioning assembly  252  which is adjustably mounted to the workstation base frame  253   a . Work surface platform  250  is adjustably mounted to the worksurface positioning assembly  252 . The worksurface positioning assembly  252  allows the work surface platform  250  to be raised and lowered relative to the cutter arm assembly  249 . The work surface platform  250  is itself adjustable to any number of angles, in conjunction with the worksurface positioning assembly  252  and in relation to the cutter arm assembly  250 .  
         [0073]     Turning now to the components of cutter arm assembly  250 . As shown in  FIG. 28A , the motor  200  is mounted actually with the shaft housing  256 . The motor mounting plate  190  is fixed to the motor  200  by means of a plurality of motor mounting plate bolts  198 .  FIG. 28B  shows the motor mounting plate  190  having a motor mounting plate central aperture  201   a  into which the externally threaded clutch and primary shaft enclosure first end  201  is disposed. Once disposed, the clutch and primary shaft enclosure first end is secured by means of motor mounting plate set screw  190   a . The opposing end of the cutter arm, the clutch and primary shaft enclosure second end  217   c  is internally threaded. The externally threaded gear case neck  217   a  is disposed within the internally threaded clutch and primary shaft enclosure second end  217   c . The gear case  217  is equipped with a gear case nipple  193  for lubrication purposes.  FIG. 28A  further shows the motor shaft  208  dispose through the center of the motor mounting plate  190 , extending into the center of shaft housing  256 .  FIG. 28C  illustrates the relationship between the first clutch plate  211  and the second clutch plate  212 . The first annular sleeve  202  is attached to the first clutch disk  211   a . This attachment is strengthened by a plurality of triangular first clutch plate supports  216   b  mounted at pre-determined intervals around the first annular sleeve. The first annular sleeve  202  exhibits the first annular sleeve slot  202   a . The motor shaft  208  is disposed within the first annular sleeve. The motor shaft  208  exhibits a corresponding longitudinal motor shaft slot  216  first key  216   a  is of such dimensions that it may be simultaneously disposed within first annular sleeve slot  202   a  and longitudinal motor shaft slot  216 , thereby locking motor shaft  208  and first annular sleeve  202  in rotation. First key  216   a  is secured with first clutch plate set screw  204   b . Clutch plate alignment pin  195   a  is inserted through first clutch disk central opening  211   d  until it comes into contact with the first annular sleeve internal stop  215   c . This allows a pre-determined length of the clutch plate alignment pin  195   a  to protrude from first clutch disk central opening  211   d . Second clutch plate  212  is attached to second annular sleeve, and again is strengthened with the plurality of second clutch disk supports  213   a  and a configuration substantially similar to that scene with the first clutch plate  211 . The clutch plate alignment pin  195   a  is disposed through the second clutch disk central opening  212   e  and extends into the second annular sleeve and will rest against any second annular sleeve internal stop  215   b . When the motor shaft  208  is in its fixed position within the first annular sleeve  202 , the distance between the end of the motor shaft  208  and the first annular sleeve internal stop  215   c  is somewhat longer than the length of the clutch plate alignment pin  195   a . This will allow the first clutch disk  211   a  and the second clutch disk  212   b  with its clutch plate friction inducing surface  212   a  will allow full contact with one another. Cutter drive shaft spring  209  is disposed within the second annular sleeve on the side of the second annular sleeve internal stop  215   b  opposed to the location of the clutch plate alignment pin  195   a . The end of primary shaft  195  is narrowed to form a positioning rod  195   g  which is disposed a short distance within cutter drive shaft spring  209 . Longitudinal primary shaft slot  195   b  in primary shaft  195  receives second key  195   c  which is also received within second annular sleeve slot  215   a . Second key  195   c  is secured by second clutch plate set screw  204   a  and prevents the primary shaft  195  from rotating within the second annular sleeve. This configuration allows lateral movement of the second annular sleeve  215 , along the primary shaft thereby allowing cutter drive shaft spring  209  to exert a force against second clutch plate  212 , which in turn allows pressure to be exerted against first clutch plate  211 . Primary shaft first bearing  203  is pressed onto primary shaft  195 . Turning again to  FIG. 28A , it is seen that when the primary shaft  195  is disposed within clutch and primary shaft enclosure  199 , primary shaft first bearing  203  is pressed into and rests in clutch enclosure bearing seats  199   a . The primary shaft  195  extends along and within the clutch and primary shaft enclosure through gear case neck  217   a  and into gear case  217 . A primary shaft second bearing  203   a  is pressed onto primary shaft  195  in such a position and it is pressed into and seats into another clutch enclosure bearing seat  199   a . The first beveled gear  210  is mounted on the end of primary shaft  195  that extends within gear case  217 . A secondary shaft  206  is disposed within the gear case  217  at right angles to the axis of the primary shaft  195 . A secondary shaft first bearing  194  is pressed onto the end of secondary shaft  206 . Secondary shaft first bearing  194  is then pressed into and rests within one of the gear case bearing seat  194   b . The second beveled gear  205  is mounted on the secondary shaft in such a position as to communicate with first beveled gear  210  at the end of primary shaft  195 . A secondary shaft second bearing  194   a  is pressed onto secondary shaft  206  and extends through gear case  217  terminating at arbor  109   b . The arbor  109   b  then receives the cutter  69 , which is secured by a nut. Clutch and primary shaft enclosure  199  has a clutch access opening  196   a  covered by cover plate  196 . The clutch and primary shaft enclosure has two internally threaded apertures corresponding to two apertures in cover plate  196  and is held in place by bolts. It will be noted that cutter drive assembly  195   d , shaft housing  256 , and clutch access opening  196   a  are respectively and separately shown in  FIG. 28D ,  FIG. 28E  and  FIG. 28F .  
         [0074]     An alternative embodiment of the machine capable of routing and shaping is illustrated in  FIG. 29A . This illustrates secondary shaft  206  equipped with routing chuck  207 . Mounted in routing chuck  207  is straight router bit  207   a . As the work piece is moved past straight router bit  207   a , a milling operation is produced on work piece W. Although straight router bit  207   a  is illustrated, router or shaper bits and other configurations may be utilized such as cove bit  207   c .  FIG. 29C  illustrates a configuration where the clutch and primary shaft enclosure  199  is rotating allowing production of an angled groove in work piece W. Returning to  FIG. 29A , cutter stabilization clamp  245  is seen in place. Cutter stabilization clamp  245  mutually communicates with clutch and primary shaft enclosure  199  and first work surface  61  and second work surface  61   a .  FIG. 29B  shows the major components of the cutter stabilization clamp. The major components being arm clamp  246  which communicates with clutch and primary shaft enclosure  199 , table clamp  248 , which communicates with first work surface  61  and second work surface  61   a . Arm clamp  246  is composed of clamping jaw  246   c  and cutter arm anvil  246   e . Clamping jaw  246   c  exhibits jaw hooking end  246   a  and jaw adjusting end  246   b . Jaw hooking end  246   a  substantially conforms to the shape of the clutch and primary shaft enclosure  199 . The jaw adjusting end  246   b  contains jaw adjusting internally threaded aperture  246   q  through which the clamping bracket adjusting handle  246   h  is disposed. The clamping jaw  246   c  hingeably communicates with cutter arm anvil  246   e  by means of clamping arm hinge pin  246   d  inserted through apertures in a pair of hinge flanges  246   i  and through a corresponding aperture in cutter arm anvil  246   e . Cutter arm anvil  246   e  is mounted to arm clamp shaft  246   f . Arm clamp shaft  246   f  is inserted into arm clamp base  247  and is adjustable in an upward and downward direction. The arm clamp base is fixed in place by arm clamp base locking handle  247   b  which is disposed within arm clamp base internally threaded aperture  247   a . Arm clamp base  247  is mounted to clamping base  248   c  of table clamp  248 . Clamping base  248   c  exhibits clamping base first end  248   d  and clamping base second end  248   i .

Adjusting block  248   a  is mounted to clamping base  248   c . After insertion through adjusting tab smooth bore  248   e , adjusting block snap ring  248   m  is mounted within the snap ring seat  248   n  on adjuster handle  248   l . Adjusting block snap ring  248   m  now rests between adjusting tab  248   g  and adjusting block  248   a . When adjuster handle  248   l  is rotated out of adjusting block  248   a , adjusting block snap ring  248   m  engage adjusting tab  248   g  causing adjustable hooking bracket  248   h  to move and clamp over second work surface  61   a  whereby clamping the cutter stabilization clamp to the work surfaces. Arm clamp shaft  246   f  is then adjusted to the proper height such that clutch and primary shaft enclosure  199  is cradled in the cutter arm anvil  246   e . When clamping bracket adjusting handle  246   h  is rotated, the threaded end that comes into contact with the arm clamp shaft causing the clamping jaw to clamp the clutch and primary shaft enclosure  199  between itself and the cutter arm anvil  246   e .  FIGS. 2A and 2B  show the relative position of the work surface platform  250  and cutter  69  when the work surface positioning assembly is extended as in  FIG. 2A  and contracted as in  FIG. 2B . As seen in  FIG. 2A , the first work surface  61  is attached to the left horizontal member  39  to a hinge assembly  44 . Hinge assembly  44  is composed of a series of work surface hinge components  44   a , which communicate with a series of left horizontal member hinge components  44   b  by means of a horizontal member hinge pin  56  extending through the hinge components and held in place by horizontal hinge pin snap ring  60 . Left horizontal member  39  is pivotally attached to left adjuster strut. While left horizontal member  39  is again pivotally attached to the left table elevation lever  28 . Left adjuster strut  40  is attached to outer left bracket member  29  and inner left bracket member  29   a . The left table elevation lever  28  is similarly pivotally attached to outer left bracket member  29  and inner left bracket member  29   a . The left table elevation lever  28  extends below and between the outer left bracket member  29  and inner left bracket member  29   a  and is curved toward and extends beyond the front of the work surface positioning assembly  252  and terminates at left handle attachment end  28   a . As shown in  FIG. 8 , the left handle attachment end  28   a  of the left table elevation lever  28  is attached to handle bar  64 , which extends horizontally to the right side of the work surface positioning assembly  252  and attaches to right handle attachment end  28   b  of the corresponding right table elevation lever  28   c . Also shown in  FIG. 8 , the right table elevation lever  28   c  extends between and is pivotally attached to the inner right bracket member  29   b  and outer right bracket member  29   c . The right table elevation lever  28   c  then extends upward to be attached to the right horizontal member  39   a . The right horizontal member  39   a  communicates with right adjuster strut  39   d , which in turn communicates and is pivotally mounted between the inner right bracket member  29   b  and the outer right bracket member  29   c .  FIG. 2B  further shows left fine adjuster strut  24  which communicates with the outer left bracket member  29  and inner left bracket member  29   a .  FIG. 3  illustrates the left fine adjuster strut  24 . A first vertical strut component  24   a  and a second vertical strut component  24   b  extend upward from adjuster strut base  24   c . Left adjuster strut  40 , which is mounted between outer left bracket member  29  and inner left bracket member  29   a  is also mounted between first vertical strut component  24   a  and second vertical strut component  24   b . Adjuster strut pivoting fastener  33  is inserted through second vertical strut component aperture  33   a , then through outer left bracket member  29 , through left adjuster strut  40 , through inner left bracket member  29   a  and finally through first vertical strut component aperture  33   d  . First vertical strut component  24   a  and second vertical strut component  24   b  are mounted to the horizontal face  24   d  of adjuster strut base  24   c . The vertical face  24   e  of adjuster strut base  24   c  contain a plurality of lateral adjust apertures  24   f , which correspond to base support circular apertures  20   a . Adjuster strip bolts  49  inserted through lateral adjust apertures  24   f , through base support circular apertures  20   a  and are fixed in a position utilizing adjuster strip nuts  49   a . Due to the oblong nature of lateral adjust apertures  24   f , the left fine adjuster strut  24  may be moved laterally along base support  20  allowing the lateral strut adjustment and allowing adjustment of the work surface positioning assembly  252  as a whole. Horizontal face  24   d  also contains internally threaded vertical adjust apertures. Externally threaded vertical adjustment bolts  25  are inserted through vertical adjustment lock nuts  26  and then through vertical adjust apertures  50 .

         [0075]      FIG. 9B  illustrates the position of work surface height adjuster  11  in relation to the height adjuster frame  307 .  FIG. 9C  illustrates the position of the work surface angle adjuster  9  also in relations to height adjuster frame  307 .  FIG. 9A  shows the work surface angel adjuster  9  operating on the worksurface surface platform  250 .  
         [0076]     Left fine adjuster strut  24  is mounted to base support  20  extending across the work station base frame  253   a . The right fine adjuster strut  24   g  is constructed similar to the left fine adjuster strut  24  and communicates a similar fashion with base support  20  and the outer right bracket member  29   c  and the inner right bracket member  29   b .  FIG. 8  shows the face frame  57 , which is part of the work station base frame  253   a . The face frame  57  communicates and is permanently mounted to both the inner right bracket member  29   b  and the inner left bracket member  29   a  and the inner right bracket member  29   b  and the outer right bracket member  29   c . Also shown in  FIG. 8  is the face frame  57 , the upper left corner of which is truncated to allow the work surface positioning assembly  250  to tilt as is illustrated in  FIG. 8 . Returning to  FIG. 2B , it can been seen when handle bar  64  is raised, the table elevation assembly  41  collapses and the work surface positioning assembly  250  is lowered, allowing the left horizontal member  39  and the corresponding right horizontal member  39   a  to rest on outer left bracket member  29  and inner left bracket member  29   a  and rest on inner right bracket member  29   b  and outer right bracket member  29   c  as seen in  FIG. 2A . Conversely, when the handle bar  64  is fully lowered, the work surface positioning assembly  250  is at its maximum height.  FIG. 2B  also shows the work surface height adjuster  11  which is attached to face frame  57 . Turning now to  FIG. 7 , it is seen that work surface height adjuster  11  is attached to face frame  57  by means of height mounting first strut  30  and height mounting second strut  30   a .  FIG. 5  shows the work surface height adjuster  11  in detail. A height adjuster central rod  32  exhibits two circumferential grooves  48   a  at the height adjuster central rod first end  32   f .  FIG. 6A  shows the height adjuster universal block  59  equipped with a bore through which height adjuster central rod  32  is inserted. The height adjuster universal block is positioned on height adjuster central rod  32  between circumferential grooves  48   a  and central rod snap rings  48  are inserted into the circumferential grooves  48   a  fixing the position of height adjuster universal block  59  on height adjuster central rod  32 . Turning now to  FIG. 4 , it can be seen that the height adjuster universal block  59  is pivotally mounted within hinge box  58 . Hinge box  58  is attached to the left horizontal member  39 . This provides the work surface height adjuster with its attachment to the work surface platform  250 . Returning to  FIG. 5 , it is seen that height adjuster central rod  32  is disposed through height adjuster first cap  34 , first cap sealing washer  32   d  and first cap dust wiping washer  32   e . The central rod is then disposed through height adjuster annular section  35  which has a height adjuster annular section first end  35   b  and a height adjuster annular section second end  35   a , both of which are externally threaded. The internally threaded height adjuster first cap is then exposed over the height adjuster annular section first end  35   b  securing first cap sealing washer  32   d  and first cap dust wiping washer  32   e . The externally threaded height adjuster annular section second end  35   a  is then disposed within height adjuster second cap wherein second cap ceiling washer  32   a  and second cap dust wiping washer  32   b  are retained. Turning again to  FIG. 7 , it shows height adjuster annular section  35  in place through height quick adjust block  37 .  FIG. 7  also shows a view of height adjuster first cap  34  with first cap internally threaded aperture  34   f . The threads of the first cap internally threaded aperture  34   f communicate with external threads of height adjuster central rod second end  32   g . It is this communication, which allows fine adjusting movements of central rod  32 . The externally threaded height adjuster central rod second end  32   g  is attached to cranking handle  27 . Returning now to  FIG. 7 , it further shows the height quick adjust block  37 . The height quick adjust block  37  exhibits an internally threaded top surface aperture  36   b  disposed within internally threaded top surface aperture  36   b  is pad  36   a  and externally threaded height adjust block set handle  36 . The height adjust block set handle  36  may be deployed to secure height adjuster annular section  35  in a given position within height quick adjust block  37 . Height quick adjust block  37  exhibits height quick adjust block smooth bore aperture  37   a  and opposing height quick adjust block smooth bore aperture  37   b  and are designed to receive partially threaded pins  31 . Height mounting first strut  30  is attached to height quick adjust block  37  by the partially threaded pins  31  which are inserted through lock washer  31   a  then through internally threaded first strut aperture  31   b . Height mounting second strut  30   a  is attached to height quick adjust block in a similar fashion allowing the height quick adjust block to pivot between height mounting first strut  30  and height mounting second strut  30   a .  FIG. 4  illustrates the attachment of the height adjuster central rod  32  to the left horizontal member  39  by the insertion of the height adjuster universal block  59  into hinge box  58  by aligning the internally threaded hinge box  51  and  51   b  with the height adjuster universal block smooth bores  59   a  and  59   b . The external threads of first threaded pin  52  and second threaded pin  52   a  are disposed within the internally threaded hinge box apertures  51  and  51   b  allowing the pins to engage the height adjuster universal block  59  less allowing the height adjuster universal block  59  to pivot within hinge box. Hinge box  58  is fixed by hinge box mounting plate  58   a  which is fixed to the left horizontal member  39 . Returning now to  FIG. 2B , it can be seen that quick adjustment of the work surface platform is achieved by loosening height adjust block set handle  36  allowing height adjuster annular section  35  to slip within height quick adjust block  37 . Upon achieving the approximate position, height adjust block set handle  36  is tightened. Further refinement of height may be achieved by rotating the height adjuster central rod  32  by turning cranking handle  27 .  FIG. 8  shows the work surface angle adjuster  9 . It is constructed substantially similar to the work surface height adjuster  11 . The work surface angle adjust is mounted to the right horizontal member  39   a .  FIG. 6B  illustrates the height adjuster universal mounting bracket  240 . The angle adjuster universal block is substantially similar to the height adjuster universal block  59 . The angle adjuster universal block  58   b  is inserted between angle block mounting bracket first strut  240   d  and angle block mounting bracket second strut  240   f  and is secured by angle block partially threaded pin  240   a  and angle block partially threaded pin  240   b . The pins are then inserted within angle strut internally threaded apertures  240   c  allowing angle adjuster universal block  58   b  to pivot therein. Returning to  FIG. 8 , it illustrates the work surface angle adjuster being attached to the angle adjuster mount  241   b  which is in turn attached to the right horizontal member  39   a.    
         [0077]     Now turning to  FIG. 10 , which shows the mechanism quickly adjusting the work surface to predetermined angles. Work surface connector  46  exhibits a plurality of work surface connector stops  80  positioned partially around exterior surface.  FIG. 15B  best illustrates the relationship of the work surface connector  46  to the first work surface  61  and the second work surface  61   a . The work surface connector  46  is attached to first side panel  61   e  of the first work surface  61  and the left side panel  61   h  of the second work surface  61   a . Now returning to  FIG. 10 , it is seen that work surface connector stops  80  are positioned such that when engaged by rocker assembly stop arm  79 , the work surfaces are fixed at certain predetermined angles such as 22.5 degrees, 45 degrees, 67.5 degrees, etc. Rocker assembly stop arm  79  is inserted through slide bracket  81 .  FIG. 11  shows that slide bracket  81  contains slide bracket slot  79   a  which exhibits overhanging retention flanges  81   a , which capture the rocker assembly stop arm. The rocker assembly stop arm  79  contains a stop arm aperture  79   c  through which stop arm threaded knob  78  passes. Internally threaded stop arm retention washer  79   b  rests below rocker assembly stop arm  79 . When stop arm threaded knob  78  is tightened, the stop arm retention washer  79   b  is drawn tight against the rocker assembly stop arm which in turn is drawn tight against the retention flanges thereby locking the rocker assembly stop arm  79  in place. By adjusting the position of the rocker assembly stop arm  79  within slide bracket  81 , small variances in the angle of the work surfaces can be achieved and the angle of the work surface can best be calibrated to predetermined angles. Returning to  FIG. 10 , it is seen that slide bracket  81  is mounted to rod  88 . Rocker bracket  85 , which is mounted to the right horizontal member  39   a , contains two corresponding flanges, rocker bracket first flange  85   a  and rocker bracket second flange  85   b . Rocker bracket first flange  85   a  and rocker bracket second flange  85   b  contain two corresponding apertures through which rod  88  extends. Rod  88  rotates freely within those apertures. Slide bracket  81  is mounted on that portion of rod  88  resting within rocker bracket  85 . Right horizontal member  39   a  exhibits a cutout  79   c  allowing the rocker assembly stop arm to assume a proper position in relation to the work surface connector stop  80 . Externally threaded sleeve  87  is received within right horizontal member threaded aperture  39   b  in addition to being held within the corresponding apertures of the rocker bracket first flange  85   a  and rocker bracket second flange  85   b , rod  88  is mounted within threaded sleeve  87  allowing free rotation. Rocker handle  82  attached to rod  88  allows rotation of rod  88  and consequent movement of the rocker assembly stop arm toward or away from work surface connector stops  80 . The threaded sleeve  87  extends through angled flange  39   c  and through slotted brace  67 . Slotted brace washer  70   a  is placed over threaded sleeve  87  and slotted brace knob  70  is mounted thereon. When slotted brace knob  70  is tightened, it secures slotted brace  67  in position. Slotted brace  67  is pivotally attached to slotted brace bracket  67   a . Slotted brace bracket  67   a  is mounted to front rail  42 . Front rail  42  is, in turn, mounted to the second work surface  61   a  at the second work surface assembly front panel  61   f . The ability to secure slotted brace  67  by means of slotted brace knob  70  allows the work surface to be positioned between predetermined angles established by the work surface connector stops  80 .  FIG. 12  illustrates the relationship between the first work surface assembly  300 , the cutter  69 , and the second work surface assembly  300   a . Within the first work surface assembly  300  is first work surface  61 . Similarly within the second work surface assembly  300   a  is second work surface  61   a . First work surface  61  and second work surface  61   a  are separated by a space, the width of which is modifiable by the activation of the first inserted adjusting means  301  and the second inserted adjusting means  301   a . When the inserted adjusting means are activated, the distance between the first work surface insert  76  and the second work surface insert  76   a  is either narrowed or expanded. The cutter  69  mounted to the cutter arm  90  rides on the cutter arm positioning assembly  251  forward and between the first work surface insert  76  and the second work surface insert  76   a  thereby performing a cross cut on the work piece. Further, the cutter arm positioning assembly  251  may be locked in any position, completely rearward, completely forward or any variation inbetween. At any fixed position, a chop cut can be performed or a rip cut can be performed by moving the work piece into the cutter. In addition, if the shape of the piece to be milled warrants, the cut can be initiated in a chop cut fashion cutting through or to any desired depth and then the cut may be transformed into the cross cut or rip cut.  FIG. 13  illustrates the cutter arm lock  107 . Cutter arm  90  is capable of 360 degree rotation and contains a plurality of clutch and primary shaft enclosure smooth bores  116  around its circumference at predetermined positions. Central rod knob  94  is fixedly mounted to cutter arm lock central rod first end  103   a . Cutter arm lock central rod second end  103   b  extends through clutch and primary shaft enclosure smooth bores  116  thereby locking cutter arm  90  at a predetermined position which in turn determines the angle of the cutter  69 . The travel of the cutter arm lock central rod  103  through the clutch and primary shaft enclosure smooth bores  116  is limited by central rod stop  105 . Positions and consequent angles between those established by the clutch and primary shaft enclosure smooth bores  116  are achieved by the use of the brake  92   a  of the cutter arm lock shoe  92 . The brake  92   a  having a concave face which communicates with the convex exterior of cutter arm  90 . Cutter arm lock shoe  92  exhibits an externally threaded cutter arm lock shoe neck  104 . Cutter arm lock central rod  103  extends through shoe setting neck aperture  104   a  which itself extends through brake  92   a . The shoe setting neck aperture  104   a  is large enough to accommodate central rod stop  105  as well as shoe setting spring  102  which when in position over the cutter arm lock central rod  103  and within cutter arm lock shoe  92 , rests against central rod stop  105 . The shoe setting cap  95  exhibits an internally threaded shoe setting cap aperture and also large enough to accommodate shoe setting spring  102 . The shoe setting cap exhibits a shoe setting cap first end  95   b  and a shoe setting cap second end  95   c . Shoe setting cap first end  95   b  exhibits a shoe setting cap central bore  95   d . Shoe setting cap tube  106  is disposed over shoe setting cap central bore  95   d . Shoe setting cap tube  106  exhibits shoe setting tube snap ring grooves  106   a  designed to receive shoe setting tube snap rings  115 . The cutter arm lock central rod extends through shoe setting cap tube  106 . Shoe setting cap handle  93  is mounted to shoe setting cap tube  106  and operates to rotate shoe setting cap  95  allowing it to be disposed over the cutter arm lock shoe neck  104 . This compresses shoe setting spring  102  between shoe setting cap  95  and central rod stop  105 . When central rod knob  94  is pulled, cutter arm lock central rod  103  is withdrawn from the clutch and primary shaft enclosure smooth bores  116  releasing the cutter arm  90  and allowing the rotation. If the cutter arm lock central rod second end  103   b  is outside an aperture and riding on the surface of cutter arm  90 , shoe setting spring  102  exerts pressure on central rod stop  105  which transmits the pressure to the cutter arm lock central rod  103  such that when the cutter arm lock central rod second end  103   b  encounters a succeeding clutch and primary shaft enclosures smooth bores  116 , cutter arm lock central rod  103  is automatically seated.  FIG. 14  shows an alternative embodiment of the cutter arm assembly  249  as well as the cutter arm lock  107 . Turning first to the cutter arm lock mechanism  107 , it is seen that collar  114  is composed of a collar first leg  114   a , collar second leg  114   b , and a transverse collar section  114  joining the two legs. Collar first leg  114   a  exhibits collar first bore  114   d , while collar second leg exhibits collar second bore  114   e . Cutter arm  90  is disposed through collar first bore  114   d  and collar second bore  114   e . The transverse collar section  114   c  also exhibits central angular transverse collar section aperture  114   f  through which shoe setting cap tube  106  is disposed. Shoe setting cap tube  106  is held in position by shoe setting tube snap rings  115 . When the cutter arm lock  107  is rotated clockwise onto the cutter arm lock shoe neck  104 , it causes cutter arm lock shoe  92  to pull away from cutter arm  90 . This allows the cutter arm to be repositioned. When the cutter arm lock  107  is rotated counter clockwise, cutter arm lock shoe  92  and brake  92   a , frictionally engages cutter arm  90  allowing cutter arm to be positioned at any angle in addition to the angle predetermined by the location of clutch and primary shaft enclosures smooth bores  116 . Collar positioning tabs  91  respectively contain collar positioning tab openings  91   b  through which collar positioning tab set screws  91   a  attach collar positioning tabs  91  to cutter arm  90 . The collar positioning tab openings are elongated and oriented toward opposing corner of the collar positioning tabs  91 . This allows the position of the collar  114  to be adjusted to facilitate the seating of cutter arm lock central rod  103  within clutch and primary shaft enclosure smooth bores  116 .  
         [0078]     Returning to the alternative embodiment of the cutter arm and cutter drive mechanism. Here, in contrast to the preferred embodiment, the motor  101  is mounted perpendicularly to the longitudinal axis of cutter arm  90  on motor mount  100 . Motor mount  100  also exhibits a motor mount annular shaft  101   a  extending perpendicularly from the plane of motor mount  100 . Mounted to cutter arm  90  is plate  96 . Plate  96  contains a plate annular aperture  101   b  within which motor mount annular shaft  101   a  is disposed such that motor mount  100  may rotate. Plate set screw  96   a  is disposed within plate set screw aperture  96   b  and plate  96  such that the set screw communicates with motor mount annular shaft  101   a , hocking plate  96 , and consequently cutter arm  90  in a fixed position. Belt drive motor  101  is attached to it. First pulley  98  that communicates with drive belt  97 , which in turn communicates with the second pulley  109 , located at bearing closure  89 . Bearing closure  89  is to tubular in shape and mounted to cutter arm extension  77 . Cutter arm extension  77  is tubular in nature and is disposed of within tubular cutter arm  90  and is held in a particular position by  90   a . Further cutter arm extension  77  may be rotated within cutter arm  90  allowing precise calibration of the angle of the cutter  69  in relation to the clutch and primary shaft enclosure smooth bores  116 . Bearing sets  113  are mounted at each end of tubular bearing and closure  89 . Axle  108  is disposed through bearing sets  113  and disposed within bearing enclosure  89  and is mounted perpendicularly on and to cutter arm extension  77 . Second pulley  109  is mounted to axle first end  108   a  with arbor  109   b  mounted to axles second end.  FIG. 15D  is a perspective view of portions of the first work surface assembly  300  and second work surface assembly  300   a . A portion of first work surface assembly  300  is designated as first work surface  61 . Not only are we extending from first work surface  61  is first work surface front panel  305 , the first work surface outer panel  304 , first work surface rear panel  303 , first work surface inner panel  302 . In combination with first work surface top panel  306  creates a rectangular box-like configuration with an open bottom comprising the first work surface  61 . On the interior edge of first work surface top panel  306 , the first work surface front panel  305 , the first work surface rear panel  303 , the first work surface top panel  306 , and the first work surface inner panel  302  are modified to form a top panel ledge  306   d . Turning now to  FIG. 15A , it is seen that the first work surface insert  76 , has first work surface insert horizontal component  76   c  and a first work surface insert vertical component  76   b . In its retracted position, the first work surface insert horizontal component  76   c  rests on the top panel ledge  306   d  such that the first work surface  61  is flush with the first work surface insert horizontal component  76   c  forming a contiguous plane. Further, in its retracted position, the first work surface insert vertical component  76   b  rests flush with first work surface inner panel  302 . The configuration of the second work surface assembly  300   a  is substantially similar to that described above for the first work surface assembly  300 . Turning now to  FIG. 15B , it can be seen that the insert adjusting rods  74  communicate with the interior surface of the first work surface insert vertical component  76   b . The insert adjusting rods  74  extend through insert adjusting rod apertures  75   a  in first work surface inner panel  302 . The insert adjusting rod  74  are further disposed through adjusting rod compression springs  75  and thence through internally threaded spring adjuster seat  76   f , which form apertures in first work surface outer panel  304 . Spring adjuster  76   i  is then threaded into spring adjuster seat  76   f .  FIG. 15C  illustrates this relationship in a magnified view. This is repeated for both insert adjusting rods  74 . The insert adjusting rods  74  has the exit through spring adjuster seat  76   f  mutually communicate with first adjusting handle bracket  71 . As can be seen in  FIG. 15D , midway along first adjusting handle bracket  71  are two lever mounting brackets  72   d . Lever mounting bracket pin  73  extends through apertures in lever mounting brackets  72   d  and the corresponding aperture in the adjuster handle  72  allowing adjuster handle  72  to pivot. Adjuster handle  72  has a curved face portion  72   b . An alternative embodiment of adjuster handle  72  would exhibit a facet face  72   c  as can be clearly seen in  FIG. 15B . Returning now to  FIG. 15D , we see that when handle portion  72   a  rests against the handle bracket, the work surface insert is fully extended. Resting at its maximum distance from the work surface. When handle portion  72   a  is rotated away from the work surface, then the work piece support abuts the work surface. Returning to  FIG. 15B , it can be seen that when adjuster handle  72  is rotated away from the first work surface  61  adjusting rod compression springs  75  are compressed between spring adjuster  76   i  and the first work surface insert. This provides tension between the curved face portion  72   b  of the adjuster handle  72  and the first work surface outer panel  304 , allowing adjuster handle  72  to remain in the set position. Further assisting the adjuster handle to remain in set position, it is groove  74   f.    
         [0079]     Thus, it can be seen that if both the first work surface insert  76  and the second work surface insert  76   a  are fully extended, it provides the narrowest path for cutter  69  to traverse. If both work surface inserts are retracted, it provides the widest path for the cutter  69  allowing work pieces of regular dimensions to be partially positioned below the work surface and still be operated upon.  FIG. 15A  also shows front rail  42 . Front rail  42  has a series of front rail perforations  74   b  on front rail front face  42   a . Corresponding rear face perforations  76   u  of a smaller diameter occur in the opposing face of front rail  42  allowing front rail screws  42   b  to be inserted through front rail perforations  74   b , then through rear rail perforations  76   u , thence through spacer aperture  47   a , then into work surface aperture  74   g . In this way front rail  42  is mounted to the front panels of first work surface  61  and second work surface  61   a . Front rail  42  extends across and beyond the width of the work surfaces. Now turning again to  FIG. 15B , at the rear of first work surface  61  and second work surface  61   a , second rear rail  43  and first rear rail  43   a  are respectively mounted in a similar fashion as front rail  42 . However, first rear rail  43   a  and second rear rail  43  are mounted such that the cutter  69  can pass between them. Further, it can be seen that second lateral work surface extension  47   f  is comprised of first bar  47   d  and first bar first tube  47   c  and first bar second tube  47   e . First bar first tube  47   c  is inserted within second rear rail  43  and first bar second tube is inserted in front rail  44   f . The first lateral work surface extension is similar constructed and mounted opposite to the second lateral work surface extension  47   f.    
         [0080]      FIG. 15B  also serves to illustrate the configuration of attachment of work surface connector  46 . Work surface connector  46  contains four work surface connector perforations  75   g  through which insert adjusting rods  74  pass. Work surface connector  46  is secured to the second work surface inner panel  61   h  and first work surface outer panel  304 . Work surface connector  46  exhibits work surface connector first strut  46   a  and work surface connector second strut  46   b  which extends to the rear walls of their respective work surfaces. Hinge mounting brackets  76   q  is fixedly attached to the first work surface and extends parallel to first work surface outer panel until it meets work surface connector strut  46   a  and is mounted thereto. Mounted to the hinge mounting brackets  76   q  is hinge assembly  44  which consists of a plurality of hinges.  
         [0081]      FIG. 16A  shows the components of the cutter work station that allow the elevation of the cutter arm  90  and allows chop cutting and is consequently termed the elevation and chop cut carriage  112   a . Carriage lock housing  117  communicates with base hinge  138 . Base hinge  138  exhibits horizontal base end component  138   a  and vertical base hinge component  145 . Both joined by base hinge pin  139 . As illustrated in  FIG. 16A , carriage lower platform  137  is composed of carriage lower platform base  137   c , carriage lower platform first side wall  137   a  and carriage lower platform second side wall  137   d . Turning to  FIG. 16B , first catch  121  is pivotally mounted to carriage lower platform first side wall  137   a  and carriage lower platform second side wall  137   d , and extends below and through catch opening  137   e  (visible on  FIG. 16A ) such that when carriage lower platform is horizontal, first catch  121  communicates and interlocks with second catch  129  mounted on carriage lock housing top  154   a  (visible in  FIG. 20B ). When first catch  121  and second catch  129  interlock, cutter arm  90  is fixed in a horizontal position allowing cross cut and rip operations. The horizontal base hinge component  138   a  is mounted to carriage lock housing and communication with tension spring  144 , which in turn communicates with the carriage lock housing  117 . Tension spring  144  operates on the rear edge of carriage lock housing  117  through its attachment with the horizontal base hinge component  138   a  allowing the forward edge of the carriage lower platform to elevate.  FIG. 18A  illustrates the catch activating mechanism. First catch  121  exhibits first catch aperture  121   f . First catch pin  121   c  extends through an aperture in carriage lower platform first side wall  137   a  and then through second catch spacer  121   h  and out through a corresponding aperture and carriage lower platform second side wall  137   d . First catch pin  121   c  is held in position by the first catch pin head  121   k  and first catch pin snap ring mounted outside carriage lower platform second side wall  137   d  and seated in first pin annular groove  121   d . Leaf spring  121   g  is mounted between half moon tabs  121   l , which protrude from carriage lower platform base  137   c . Leaf spring  121   g  is held to the carriage lower platform base  137   c  at leaf spring bolt  121   i . Pass through leaf spring aperture  121   m  and a corresponding aperture in carriage bolt platform base  137   c  and fixed with leaf spring nut  121   j . Leaf spring  121   g  is mounted substantially in the center of the carriage lower platform base  137   c  so it corresponds with the position of first catch  121  and communicates therewith. Leaf spring  121   g  is also positioned to apply continuous pressure to catch  121 . Turning now to  FIG. 16B , it can be seen that second catch  129  is positioned in such matter that when carriage lower platform  137  is lowered toward the upper surface of carriage lock housing  117 , the first catch curved face  121   n  of first catch  121  contacts the second catch curved face  129   a  of second catch  129  such that first catch  121  depresses leaf spring  121   g  until first catch tooth  121   o  of first catch  121  passes below second catch tooth  129   b  of second catch  129 . Leaf spring  121   g  then presses on first catch  121  causing second catch tooth  129   b  and first catch tooth  121   o  to interlock. Returning to  FIG. 18A , it can be seen that first catch  121  is released from its interlock position with second catch  129  by means of offset catch cam  121   a . Second catch pin  121   p  extends through an aperture in carriage lower platform first side wall  137   a , then through third catch spacer  121   r , then through offset catch cam aperture  121   s , then through first catch spacer  121   u  and out through a corresponding aperture and carriage lower platform second side wall  137   d . Second catch pin  121   p  is held in position in a similar fashion as first catch pin  121   c . However, second catch pin  121   p  is fixed to offset catch cam  121   a . Further, second catch pin  121   p  exhibits catch handle  121   b . When second catch pin  121   p  is rotated, offset catch cam  121   a  communicates with first catch  121  which in turn depresses leaf spring  121   g . First catch  121  is moved away from second catch  129  causing first catch tooth  121   o  to disengage from second catch tooth allowing carriage lower platform  137  to rise.  
         [0082]     Carriage lower platform first side wall  137   a  and carriage lower platform second side wall  137   d  exhibit a plurality of pivotally mounted carriage struts  112   c , which also pivotally communicating with and lending support to carriage upper platform  128 . Turning now to  FIG. 16A , it is seen that the serrated arm  130  extends downward and rearward between first offset cam support  142  and second offset cam support  142   c . The serrated arm  130  communicates with serrated arm tension spring  131 , which in turn communicates with the carriage lower platform base  137   c . When the serrated arm  130  is drawn rearward, carriage upper platform  128  pivots rearward on pivotally mounted carriage struts  112   c  causing carriage upper platform  128  and consequently the cutter arm  90  to lower. At the same time the tension in the serrated arm tension spring  131  is increased. Turning now to  FIG. 17 , it is seen that the first offset cam support  142  and the second offset cam support  142   c  are mounted to carriage lower platform first sidewall  137   a  and carriage lower platform second sidewall  137   d , and extend upward and rearward. First offset cam support  142  and second offset cam support  142   c  exhibit corresponding apertures, through cam lobe axle  132   a  extends. Thus, cam lobe axle  132   a  creates a pivotal mounting for offset cam lobe  140 . Offset cam lobe  140  is fixedly attached to cam lobe axle  132   a  and mounted between first offset cam support  142  and second offset cam support  142   c . One end of cam lobe axle  132   a  exhibits cam lobe axle handle  132 . When cam lobe axle handle  132  is activated, offset cam lobe  140  rotates within first offset cam support  142  and second offset cam support  142   c . Each offset cam support exhibits an additional pair of corresponding apertures through which elongated tabs  141   a  of carriage elevation locking shoe  141  extend allowing carriage elevation locking shoe  141  to be pivotally mounted between the offset cam supports. Serrated arm catch  143  is mounted between carriage lower platform first side wall  137   a  and carriage lower platform second side wall  137   d . In this configuration, when cam lobe axle handle is activated, offset cam lobe  140  is rotated into contact with carriage elevation locking shoe  141  which in turn contacts serrated arm  130  forcing serrations  130   a  to communicate with serrated arm catch  143 . Friction between offset cam lobe  140 , carriage elevation locking shoe  141  and the upper surface of the serrated arm  130  will assist offset cam lobe  140  to maintain its position. The pressure exerted by offset cam lobe  140  causes serrated arm catch  143  to remain in position between serrations  130   a , locking the carriage upper platform  128  in a temporarily fixed position thus counteracting the tension in serrated arm tension spring  131 . Placing serrated arm catch  143  between the various serrations  130   a  determines the height of carriage upper platform  128  and consequently the height of cutter arm  90 .  
         [0083]      FIG. 19A  illustrates the carriage lock assembly  149  in its relationship to first rail  253   g . Further shown in  19 A is the carriage locking offset cam lobe  135  disposed within carriage lock cam housing  149   a .  FIG. 21  illustrates an end view of first rail  253   g . First rail  253   g  has a first rail lower component  84   a  and a first rail upper component  84   b  and their parallel configuration. First rail lower component  84   a  exhibits first rail lower component lip  84   c  while first rail upper component  84   b  exhibits first rail upper component lip  84   d . First rail lower component  84   a  and first rail upper component  84   b  exhibit a plurality of first real spacers  155 , which appear periodically along the entire length of the rails and separate first rail lower component  84   a  from first rail upper component  84   b . This separation is designed to allow the fall through of cutting dust, keeping the rails clear and smoothly operating. The rails are disposed at an inward angle relative to the carriage lock housing  117 .  FIG. 21  shows that carriage wheel  146  is disposed between the first rail lower component  84   a  and the first rail upper component  84   b . The carriage wheels  146  are disposed at an inward angle relative to carriage lock housing  117 , substantially the same as the angle at which the rails are disposed.  
         [0084]     Carriage wheel  146  communicates with carriage wheel axle  146   a . Carriage wheel  146  rides on first rail lower component lip  84   c . The first rail upper component lip  84   d  is angled towards carriage wheel  146  to such a degree that the extended lip rests above carriage wheel edge  146   c . This configuration is substantially similar for second rail  253   h . The component lips of the rails and their position above the carriage wheels rocks the plurality of carriage wheels in their position below the upper rail components and the lower rail components. Carriage wheel axle  146  is disposed within sleeve bracket  153  and communicates with wheel mounting bracket  156  and is attached to carriage lock housing left side wall  154   c . Two wheels are thus attached to carriage lock housing left side wall  154   c  and two wheels are attached to carriage lock housing right side wall  154   d  in a similar fashion. Turning to  FIG. 20B , it can be seen that carriage lock housing  117  is substantially in the shape of rectangular box having carriage lock housing top  154   a , carriage lock housing left side wall  154   c , carriage lock housing right side wall  154   d , carriage lock housing front  154   e  and carriage lock housing back  154   f . Carriage lock housing front  154   e  contains three apertures. Left rail front aperture  154   g  has a corresponding and opposed left rail back aperture  154   h . Right rail front aperture  154   a  in carriage lock housing front also has a corresponding and opposed right rail back aperture  154   k . Four apertures allow first rail  253   g  and second rail  253   h  to pass through carriage lock housing  117 . The first rail  253   g  and second rail  253   h  are disposed between work station base first transverse rail support  253   c  and work station base second transverse rail support  253   f . The carriage lock housing with its plurality on internally mounted wheels is thus allowed to traverse the length of the rails. This allows the cutter arm positioning assembly to move to and fro. Carriage lock housing front  154   e  also exhibits front rod aperture  154   i  through which control rod  124  is disposed. It should be noted that in accordance with  FIG. 20B , carriage lock cam housing  149   a  is mounted to the interior of carriage lock housing front  154   e . Turning again to  FIG. 19A , it is shown that carriage lock cam housing  149   a  exhibits opposing side walls specifically first cam housing side wall  149   b  and second cam housing side wall  149   c  as well as opposing top and bottom, specifically cam housing top  149   d  and cam housing bottom  149   e . At first cam housing side wall  149   b  and second cam housing side wall  149   c  contain corresponding apertures, first side wall cam aperture  149   f  and second side wall cam aperture  149   g .  FIG. 20  illustrates cam sleeve  134  that extends through first side wall cam aperture  149   f  through carriage locking offset cam lobe  135  and then through second side wall cam aperture  149   g . Cam sleeve  134  rotates freely within the side wall apertures, however, it is fixed within the carriage locking offset cam lobe  135   a , so that cam sleeve cam  134  rotates in conjunction with carriage locking offset cam lobe  135 . Cam sleeve  134  is annular in nature with the exception that a portion of the cam is removed along the axis resulting in cam sleeve slot  136  running the length of cam sleeve  134 . Carriage locking offset cam lobe  135  also exhibits cam lobe slot  136   a  corresponding to cam sleeve slot  136 . Cam lobe slot  136   a  is best visualized in  FIG. 21 . As seen in  FIG. 16C , control rod  124  exhibits control rod tab  124   a . Control rod tab  124   a  is configured such that its width and its height, or in other words, the maximum distance it extends from control rod  124  allows it to freely slide within cam sleeve slot  136  and cam lobe slot  136   a . Then control rod  124  is drawn forward, such that control rod tab  124   a  is disposed within cam sleeve slot  136 , when control rod  124  is rotated, control rod tab  124   a  communicates with and in turn rotates cam sleeve  134  which in turn will rotate carriage locking offset cam lobe  135 . Returning to  FIG. 19A , it will be seen that cam housing bottom  149   e  is extended to form hinge lip  152 . Stop plate  150  is hingeably mounted to hinge lip  152  through stop plate hinge pin  148 . At such time as control rod tab  124   a  is disposed within cam sleeve slot  136  and cam sleeve  134  and consequently, carriage locking offset cam lobe  135  is rotated against stop plate  150 . Stop plate  150  is forced against the first rail lower component  84   a  thus preventing carriage lock housing  117  from moving along first rail  253   g , and second rail  253   h  rotating carriage locking offset cam lobe  135  away from stop plate  150  releases carriage lock housing  117  for movement.  
         [0085]     Control rod  124  is not only used to lock carriage lock housing  117  but serves two additional purposes.  FIG. 16B  shows chop cut activating hinge  126  attached to carriage lower platform  137  through chop cut activating hinge pin  126   a . As shown in  FIG. 16C , chop cut activating hinge  126  exhibits a longitudinal chop cut activating hinge slot  126   b . When control rod tab  124   a  is located behind chop cut activating hinge  126  as shown in  FIGS. 16B and 16C , and is rotated perpendicularly to the longitudinal axis of the chop cut activating hinge slot, then when control rod  124  is drawn forward, control rod tab  124   a  engages chop cut activating hinge  126  drawing the hinge forward and pulling carriage lower platform  137  downward which results in cutter arm  90  being pulled downward and consequently results in the performance of a chop cut. When control rod  124  is released, tension spring  144  causes carriage lower platform  137  to elevate at the front. Control rod  124  may be positioned such that tab  124   a  is clear of cam sleeve  134 . At this point carriage control handle  118  may be rotated down and out of the way of cutting operations as is illustrated in  FIG. 8 .  FIG. 22A  through  FIG. 27  show the rip fence and miter gauge  160   b .  FIG. 24  illustrates the major components being adjustable base  176 , arm  171 , and fence  159 .  FIG. 26  illustrates rip fence and miter gauge mounting bracket  178  attached to adjustable base  176 , which is in turn is attached to base line  171 .  FIG. 24  illustrates extension arm  160  mounted within base arm  171  with the opposing end of extension arm pivotally attached to fence  159 . Returning to  FIG. 26 , it is seen that rip fence and miter gauge mounting bracket  178  is in the form of a U-shape of such a dimension that it would slip over front rail  42 . Rip fence and miter gauge mounting bracket  178  exhibits mounting bracket tabs  178   b  which come out above and below the open side of rip fence and miter gauge mounting bracket  178 . Tabs  178   b  prevent the rip fence and miter gauge mounting bracket  178  from being pulled off front rail  42 . This arrangement allows the rip fence and miter gauge mounting bracket  178  and consequently the rip fence and miter gauge  160   b  to slide along the length of front rail  42  keeping in mind that tabs  178   b  clear both above and below front rail spacers  47 . Returning to  FIG. 26 , it is seen that along the bottom edge of rip fence and miter gauge mounting bracket  178  is mounted internally threaded mounting bracket bridge  170 . Externally threaded bridge set screw  164  is disposed within the internally threaded aperture of mounting bracket bridge  170 . When bridge set screw  164  is rotated within the internally threaded aperture, bridge set screw  164  makes contact with bridge pressure spring  182 , which in turn makes contact with first rail  42  resulting in rip fence and miter gauge mounting bracket  178  being held in a temporarily fixed position along front rail  42 . Rip fence and miter gauge mounting bracket  178  is attached to angle bracket  177 , which in turn has a vertical angle bracket component  177   a  and a horizontal angle bracket component  177   b . Horizontal angle bracket component  177   b  contains horizontal angle bracket internally threaded aperture  177   c . Angle bracket  177  is mounted such that horizontal angle bracket component  177   b  is flush with the surface of rip fence and miter gauge mounting bracket  178 . Mounting bracket bolt  175   a  is disposed within semi-circular slot  176   a  within adjustable base  176 . When mounting bracket bolt  175   a  is rotated, in the appropriate direction, adjustable base  176  is tightened against angle bracket  177  temporarily fixing base arm  171  in position.  FIG. 24  shows two of the various positions the rip fence and miter gauge  160   b  may adopt through its arc. Semi-circular slot  176   a  exhibits a plurality of adjustment plate set screw seats  176   c . The adjustment plate set screw seats  176   c  are positioned around the semi-circular slot  176   a  in such a way that when mounting bracket bolt  175   a  is disposed within the adjustment plate set screw seats  176   c , rip fence and miter gauge  160   b  will adopt a series of predetermined angles relative to front rail  42 . Mounting bracket bolt  175   a  may be tightened at positions between the adjustment set plate set screw seats  176   c  so that angles between predetermined angles established by the location of adjustment plate set screw seats  176   c  may be obtained.  FIG. 26  also illustrates that base arm  171  pivots upon arm pin  174  which mounted to rip fence and miter gauge mounting bracket  178 . The distal end of arm pin  174  is externally threaded and the base arm  171  is retained by base arm threaded knob  173 .  FIG. 24  illustrates fence  159  with semi-circular fence component  159   a  and straight edge component  159   b . Semi-circular fence component  159   a  also exhibits fence semi-circular slot  159   c . Fence semi-circular slot  159   c  is configured substantially similar to semi-circular slot  176   a . Turning to  FIG. 27 , it is seen that fence  159  pivots about fence pin  165 . Fence pin  165  exhibits a head and an externally threaded end that is disposed through aperture and third fence surface  159   g . Then through apertures in the distal extension arm end  171   b , then through a corresponding and opposite aperture in second fence surface  159   f . Allowing fence  159  to pivot on the distal extension arm end  171   b .  FIG. 27  also exhibits horizontal pin plate component  179   b  attached to the upper surface of extension arm  160 . Vertical pin  179   c  is attached to pin plate  179   b . Vertical pin  179   c  is disposed through fence semi-circular slot  159   c . Pressure bushing  183  is then disposed over vertical pin  179   c  as is vertical pin spring  169 , spring washer  186 , and internally threaded base arm threaded knob  173   a . When base arm threaded knob  173   a  is tightened, vertical pin spring  169  compresses applying pressure to pressure bushing  183 , which rests at some point within fence semi-circular slot  159   c  or within fence component circular pressure bushing seats  185 , which are configured substantially similarly to adjustment plate set screw seats  176   a . Thereby keeping fence  159  in a predetermined position.  
       CONCLUSIONS, RAMIFICATIONS AND SCOPE  
       [0086]     The unusual versatility of this machine is apparent from the specification. The cutter arm may be raised or lowered to accommodate any shape or form of workpiece. The cutter arm may be drawn forward through the workpiece and returned to its position ready to cut again. The cutter arm may also operate on the workpiece in a chop cut fashion. By using a routing bit as the cutter many milling operations may be performed on any shape or form of workpiece. The work surface holding the workpiece may be angled as well as adjusted upward or downward again facilitating the unlimited configurations between the cutter and the workpiece. The work surface inserts maybe narrowed or widened again conforming to large workpieces or workpieces of unusual shape.  
         [0087]     It is worthy to note that although this machine may perform many functions in orienting and operating on a workpiece, the majority of those functions are control from the front of the machine increasing operator safety.  
         [0088]     It will be appreciated that although the description contains many specificities, numerous changes and modification may be made without departing from the scope of the invention. Nothing in the description should be construed as limiting the scope and the foregoing description should be construed in an illustrative and not limitative sense.
