Description:
This application is a division of U.S. patent application Ser. No. 11/859,314 filed Sep. 21, 2007 and is a continuation of U.S. patent application Ser. No. 11/859,139 filed Sep. 21, 2007. The entire disclosure of each of the above applications is incorporated herein by reference. 
    
    
     FIELD 
     The present teachings relate to a cutting tool and more particularly relate to a jigsaw with a cutting angle indicator in a jigsaw housing assembly that is visible through a window in the housing of a jigsaw housing assembly. 
     BACKGROUND 
     Typically, a jigsaw can cut perpendicular to a plane of a workpiece. In some applications, however, the jigsaw can be pivoted to form a non-perpendicular cutting angle, e.g., a bevel cut at forty five degrees. Certain applications can require that the angle, at which the jigsaw is pivoted, be at a relatively accurate and specific angle. In this instance, additional tools can be used to confirm the angle between the housing and the workpiece or tick marks can be formed on the shoe and/or the housing and used to judge the angle based on the relative position of the tick marks. 
     SUMMARY 
     In one form, the present teachings provide a jigsaw having a housing containing a motor activated by a trigger assembly. A shoe member is pivotally connected to the housing. A locking mechanism has an unlocked condition that permits the shoe member to pivot relative to the housing and a locked condition that prevents the shoe member from pivoting relative to the housing. A stop member extends from the housing and the shoe member is configured to be moved axially relative to the housing so that a portion of the shoe member engages the stop member to prevent the shoe member from pivoting relative to the housing. 
     In another form, the present teachings provide a jigsaw that includes a housing assembly, a shoe member and an indicator. The housing assembly has a housing, a motor and transmission assembly received in the housing, an output member reciprocatingly driven by the motor and transmission assembly, and a trigger coupled to the housing and configured to control operation of the motor and transmission assembly. The housing defines a window. The shoe member is pivotally coupled to the housing. The indicator is pivotally disposed in the housing. A portion of the indicator is visible through the window. Movement of the indicator is responsive to movement of the shoe member such that a rotational position of the indicator is indicative of a position of the shoe member relative to the housing assembly. 
     In still another form, the present teachings provide a jigsaw that includes a housing assembly, a shoe member and a means for indicating a position of the shoe member relative to the housing assembly. The housing assembly has a housing, a motor and transmission assembly received in the housing, an output member reciprocatingly driven by the motor and transmission assembly, and a trigger coupled to the housing and configured to control operation of the motor and transmission assembly. The housing defines a window. The shoe member is pivotally coupled to the housing. The indicating means includes indicia that is associated with a current relative position of the shoe member. The indicia is visible through the window in the housing. 
     Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present teachings.

Similarly, the terms “first,” “second” and other such numerical terms referring to structures, systems and/or methods do not imply a sequence or order unless clearly indicated by the context. 
     With reference to  FIG. 1 , a jigsaw  100  generally includes a housing  102  that can be formed of two half shells  104 ,  106 . The housing  102  can contain a motor  108 . When activated by a trigger assembly  110 , the motor  108  can provide a reciprocating and/or pendulum motion via a transmission assembly  109  (shown without detail, conventional) to a cutting blade holder  112  on an end of a reciprocating shaft to drive a cutting blade  114  at a cutting angle  116  ( FIG. 6 ), as is well known in the art. A control member  118  on a side of the housing  102  can control a rate of reciprocation and/or a magnitude of a pendulum motion of the cutting blade  114 . 
     A shoe member  120  can be coupled to a bottom  122  of the housing  102  in such a way as to permit the shoe member  120  to pivot relative to the housing  102 . As the shoe member  120  pivots relative to the housing  102 , the cutting blade  114  can be orientated at various angles (i.e., one or more of the cutting angles  116  ( FIG. 6 )) relative to the shoe member  120 . 
     A bottom surface  124  of the shoe member  120  can abut a workpiece  126 , which can be wood, plastic, metal, other suitable materials and one or more combinations thereof and can be in the form of pipe, sheet material, stock material, other suitable forms and/or materials and one or more combinations thereof. The shoe member  120  can be pivoted relative to the housing  102  to adjust the cutting angle  116  ( FIG. 6 ) of the jigsaw  100 , e.g., at a forty five degree cutting angle. As the shoe member  120  is moved relative to the housing  102 , an angle indicator wheel  128  that can be rotatably coupled to the shoe member  120  (see, e.g.,  FIG. 9 ) can indicate the cutting angle  116  of the jigsaw  100 . 
     Further, a locking mechanism  130  can include a bevel lever  132  that can be adjusted between an unlocked condition, as shown (in phantom) in  FIG. 1  and a locked condition, as shown in  FIG. 1 . In the unlocked condition, the locking mechanism  130  can permit the shoe member  120  to pivot relative to the housing  102 . In the locked condition, the locking mechanism  130  can prevent the shoe member  120  from pivoting relative to the housing  102 . In this regard, the cutting angle  116  ( FIG. 6 ) to which the shoe member  120  can be pivoted relative to the housing  102 , when the locking mechanism  130  is in the unlocked condition, can be indicated by the angle indicator wheel  128 . 
     A dust extraction port  134  can be formed on a rear portion  136  of the housing  102  such that a vacuum source  138  can be connected with various suitable connections to the dust extraction port  134 . A dust extraction airflow  140  can be extracted from a cutting area  142 . From the cutting area  142 , the dust extraction airflow  140  can move into the housing  102  near a rear edge  144  of the cutting blade  114 , through the housing  102  and out through the dust extraction port  134 . 
     The dust extraction airflow  140  can travel through the housing  102  and can be routed through an inner periphery of the angle indicator wheel  128 . In one example, the angle indicator wheel  128  can be similar to an angle indicator wheel  708  having an inner periphery  720 , as shown in  FIG. 10 . In another example, the angle indicator wheel  128  can be similar to an angle indicator wheel  758  having an inner periphery  772 , as shown in  FIG. 11 . 
     In a further example and with reference to  FIGS. 1 and 12 , the dust extraction airflow  140  can exit the cutting area  142  through a scoop member  148  that extends from the housing  102 . The scoop member  148  can be similar to a scoop member  762 , as shown in  FIG. 11 . In the above examples, the shoe member  120  can be pivoted relative to the housing  102  without interrupting the dust extraction airflow  140  through the housing  102  and through the angle indicator wheel  128 . 
     With reference to  FIG. 2 , a jigsaw  200  includes a housing  202  that can be formed of two half shells  204 ,  206 . The housing  202  can contain a motor  208 . When activated by a trigger assembly  210 , the motor  208  can provide a reciprocating and/or pendulum motion via a transmission assembly  209  (shown without detail, conventional) to the reciprocating shaft to drive a cutting blade  214  at one or more of the cutting angles  116  ( FIG. 6 ). A control member  216  on a side of the housing  202  can control the rate of reciprocation and/or the magnitude of the pendulum motion of the cutting blade  214 . 
     A shoe member  218  can be coupled to a bottom  220  of the housing  202  in such a way as to permit the shoe member  218  to pivot relative to the housing  202 . As the shoe member  218  pivots relative to the housing  202 , the cutting blade  214  can be orientated at the various cutting angles  116  ( FIG. 6 ) relative to the shoe member  218 . A bottom surface  222  of the shoe member  218  can abut the workpiece  126  ( FIG. 1 ). 
     As the shoe member  218  is moved relative to the housing  202 , an angle indicator wheel  224  can be rotatably coupled to the shoe member  218  (see, e.g.,  FIG. 9 ), and can indicate the cutting angle  116  ( FIG. 6 ) of the jigsaw  200 . Further, a locking mechanism  226  can include a bevel lever  228  that can be adjusted between an unlocked condition (e.g., in phantom in  FIG. 1 ) and a locked condition. The cutting angle  116  ( FIG. 6 ) to which the shoe member  218  can be pivoted relative to the housing  202 , when the locking mechanism  226  is in the unlocked condition, can be indicated by the angle indicator wheel  224 . 
     A dust extraction port  230  can be formed on a rear portion  232  of the shoe member  218 , in contrast to the dust extraction airflow  140  through the housing  102  ( FIG. 1 ). A vacuum source  234  can be connected to the dust extraction port  230 . A dust extraction airflow  236  can be extracted from a cutting area  238 . From the cutting area  238 , the dust extraction airflow  236  can move through the shoe member  218  and out through the dust extraction port  230  that extends therefrom. A vacuum source adapter  240  can be connected to the dust extraction port  230  formed in the shoe member  218  and can be used to connect to the vacuum source  234 . Inlets  242  can be formed at one or more locations on the shoe member  218  adjacent the cutting area  238 . From the inlets  242 , the dust extraction airflow  236  can be routed through channels in the shoe member  218  to the dust extraction port  230 . 
     With reference to  FIG. 3 , a jigsaw  300  can be similar to the exemplary jigsaw  200  ( FIG. 2 ) and can also include a keel assembly  302  and/or a laser module  304  that can be connected to a housing  306  having two housing half shells  308 ,  310  implemented in a similar fashion to the jigsaw  200 . The jigsaw  300  can further include a dust extraction airflow  312  through a shoe member  314 . The dust extraction airflow  312  can exit from a dust extraction port  316  that can extend therefrom. The laser module  304  can project a laser light  318  and can produce a laser light pattern  320 . The laser light pattern  320  can produce, for example, a sequence of dashes and/or dots beyond a front side  322  of the cutting blade  114  and can highlight a path of the cutting blade  114  through the workpiece  126 . 
     The keel assembly  302  can provide additional straight-line accuracy when cutting a straight line in the workpiece  126  (e.g., it can help avoid wandering of the jigsaw cutting line). The keel assembly  302  can be pivoted with the housing  306  when the shoe member  314  is moved at an angle (i.e., one or more cutting angles  116  ( FIG. 6 )) relative to the housing  306 . In this regard, the shoe member  314  can be pivoted relative to the housing  306  but the keel assembly  302  can remain generally in line with the housing  306  so as to provide, for example, a straight bevel cut through the workpiece  126 . 
     With reference to  FIG. 4 , a jigsaw  400  includes a housing  402  that can be formed of two half shells  404 ,  406 . The housing  402  can contain a motor  408 . When activated by a trigger assembly  410 , the motor  408  can provide a reciprocating and/or pendulum motion via a transmission assembly  409  (shown without detail, conventional) to the reciprocating shaft to drive the cutting blade  114  at one of the cutting angles  116  ( FIG. 6 ), as is well known in the art. 
     A shoe member  412  can be coupled to a bottom  414  of the housing  402  in such a way as to permit the shoe member  412  to pivot relative to the housing  402 . As the shoe member  412  pivots relative to the housing  402 , the cutting blade  114 , can be orientated at various angles (i.e., one or more of the cutting angles  116  ( FIG. 6 )) relative to the shoe member  412 . As is known in the art, a bottom surface  416  of the shoe member  412  can abut the workpiece  126  ( FIG. 1 ). 
     A locking mechanism  418  can be adjusted between an unlocked condition that can permit the shoe member  412  to pivot relative to the housing  402  and a locked condition that can prevent the shoe member  412  from pivoting relative to the housing  402 . In one example, the locking mechanism  418  can include one or more fasteners (not shown) that can secure the shoe member  412  to the bottom  414  of the housing  402 . The fasteners can be partially removed to permit the shoe member  412  to pivot relative to the housing  402 . 
     A dust extraction port  420  can be formed on a rear portion  422  of the housing  402  such that a vacuum source  424  can be connected to the dust extraction port  420 . A dust extraction airflow  426  can be extracted from a cutting area  428 . From the cutting area  428 , the dust extraction airflow  426  can move into the housing  402  near a rear side  430  of a cutting blade  114 , through the housing  402  and out through the dust extraction port  420 . 
     With reference to  FIG. 5 , a jigsaw  500  generally includes a housing  502  that can be formed of two half shells  504 ,  506 . The housing  502  can contain a motor  508 . When activated by a trigger assembly  510 , the motor  508  can provide a reciprocating and/or pendulum motion via a transmission assembly  509  (shown without detail, conventional) to the reciprocating shaft to drive a cutting blade  114  at one or more of the cutting angles  116  ( FIG. 6 ), as is well known in the art. 
     A shoe member  514  can be coupled to a bottom  516  of the housing  502  in such a way as to permit the shoe member  514  to pivot relative to the housing  502  in a fashion that is similar to the jigsaw  400  ( FIG. 4 ). A bottom surface  518  of the shoe member  514  can abut the workpiece  126  ( FIG. 1 ). In addition, a locking mechanism  520  can be adjusted between an unlocked condition that can permit the shoe member  514  to pivot relative to the housing  502  and a locked condition that can prevent the shoe member  514  from pivoting relative to the housing  502 . The locking mechanism  520  can include one or more fasteners (not shown) that can secure the shoe member  514  to the bottom  516  of the housing  502 . The fasteners can be partially removed (i.e., the unlocked condition) to permit the shoe member  514  to pivot relative to the housing  502 . 
     A storage container  530  can be formed on a rear portion  532  of the housing  502  such that blades, tools, etc. can be stored within the storage container  530 . A storage container cover  534 , illustrated in an open condition, can be closed (shown in phantom line) to contain whatever may be placed within the storage container  530 . 
     With reference to  FIG. 6 , the cutting angle  116  of the cutting blade  114  of the jigsaw  300  is shown relative to the shoe member  314  of the jigsaw  300 . The keel assembly  302  is also attached to the housing  306 . The cutting angle  116  (illustrated in solid line) is positioned at the zero degree cutting angle, i.e., a perpendicular cutting angle relative to the shoe member  314 . The cutting angle  116  can also be positioned at one or more cutting angles such as a cutting angle  352  (shown in phantom line) that can be positioned at about positive fifteen degrees, while a cutting angle  354  (shown in phantom line) can be positioned at about negative thirty degrees. A cutting angle  356  (shown in phantom line) can be positioned at about positive forty five degrees. It will be appreciated in light of the disclosure that various cutting angles can be implemented with any of the jigsaws  100 ,  200 ,  300 ,  400 ,  500  ( FIGS. 1-5 ). 
     With reference to  FIGS. 1-5 , it will be appreciated in light of the disclosure that any of the jigsaws  100 ,  200 ,  300 ,  400 ,  500  can be adjusted to provide one or more of the cutting angles  116  with or without the keel assembly  302  attached thereto. Moreover, the shoe member  120 ,  218 ,  314 ,  416 ,  516  can be positively locked to the housing  102 ,  202 ,  306 ,  402 ,  502 , in addition to positioning the locking mechanism  130 ,  226 ,  422 ,  522  in the locked condition when the shoe member  120 ,  218 ,  314 ,  416 ,  516  is in the zero degree angular position or at other predetermined angular positions. In this regard, the shoe member  120 ,  218 ,  314 ,  416 ,  516  can be moved axially relative to a cutting direction of the jigsaw  100 ,  200 ,  300 ,  400 ,  500 , to further lock the shoe member  120 ,  218 ,  314 ,  416 ,  516  to the housing. With reference to  FIGS. 19 and 20 , a shoe member  900  can be moved in a direction  914  that is axially backward relative to a cutting direction of the jigsaw. With reference to  FIG. 21 , a shoe member  950  can be moved in a direction  960  that is axially forward or in line with a cutting direction of the jigsaw, as is discussed below. 
     With reference to  FIG. 7 , a window  600  can be formed in a housing  602  through which a portion of an angle indicator wheel  604  can be displayed. Numbers  606  can be affixed to the angle indicator wheel  604  such that certain numbers  606  can be displayed in the window  600  to indicate a specific angular position of the shoe member  120 ,  218 ,  314  ( FIGS. 1-3 ) relative to the workpiece  126  ( FIG. 1 ). It will be appreciated in light of the disclosure that the numbers  606  are but one example of the information that can be displayed through the window  600 . Other icons, graphics, symbols, specific indicia and/or one or more combinations thereof can be used and, as such, can be descriptive of angular increments between zero degrees and forty five degrees. For example, a line  608  ( FIG. 8 ) can be aligned with the numbers  606 . 
     The window  600  in the housing  602  can further contain arrows  610  and/or one or more other suitable additional indicators that can provide for a relatively more precise alignment of the angle indicator wheel  604  in the window  600  and thus at a desired cutting angle. In this regard, the user can more readily identify the exact position of the shoe member  120 ,  218 ,  314  based on the position of the numbers  606  and/or other graphics, icons, etc. in the window  600  relative to the arrows  610  formed around the window  600 . It will be appreciated in light of the disclosure that the window  600 , as described above, can be implemented on any of the jigsaws  100 , the jigsaw  200  and/or the jigsaw  300 . 
     In one example and with reference to  FIG. 8 , a window  620  can include a perimeter illumination mechanism  622  that can illuminate numbers  624  on an angle indicator wheel  626  to more readily view the numbers  624 . The perimeter illumination mechanism  622  that can emanate light  628  from the entire inner periphery  630  of the window  620  or portions thereof. The perimeter illumination mechanism  622  can include one or more light emitting diodes of one or various colors, one or more small incandescent bulbs and/or one or more combinations thereof to provide suitable illumination to the angle indicator wheel  626 . 
     With reference to  FIG. 9 , an angle indicator wheel  640  can contain within the angle indicator wheel  640  (or adjacent thereto), an illumination source  642  that can shine through the angle indicator wheel  640  and illuminate numbers  644  thereon. By illuminating the angle indicator wheel  640 , portions of the angle indicator wheel  640  can glow (i.e., emit light  646 ) as viewed through a window  648 . The glowing angle indicator wheel  640  can be shown to more readily highlight the numbers  644  on the angle indicator wheel  640 . It will be appreciated in light of the present disclosure that the window  600 , the window  620  or the window  648  can be implemented on the jigsaw  100 , the jigsaw  200  and the jigsaw  300 . 
     With reference to  FIG. 10 , a dust extraction airflow  700  can be directed through an airflow pathway  702  that can be established by an exemplary housing  704  of a jigsaw  706 . In one example, a portion of the airflow pathway  702  can be through an angle indicator wheel  708 , which can be similar to the angle indicator wheel  128  ( FIG. 1 ). The dust extraction airflow  700  can begin at a rear edge  710  of the cutting blade  114 . The dust extraction airflow  700  can continue up into the airflow pathway  702  that can be provided by multiple ribs  712  formed in the housing  704 . 
     The dust extraction airflow  700  can continue through the airflow pathway  702  that can continue through the housing  704 , above a shoe block member  714  toward a rear portion  716  of the housing  704 . The dust extraction airflow  700  can turn downward through the airflow pathway  702  toward a shoe member  718  and can be directed through an inner periphery  720  of the angle indicator wheel  708  so as to define a portion of the airflow pathway  702  therethrough. The dust extraction airflow  700  can move through the angle indicator wheel  708  and out through a dust extraction port  722  formed in the rear portion  716  of the housing  704 . 
     A vacuum source  724  can attach to the dust extraction port  722  formed in the housing  704  to establish the dust extraction airflow  700  through the airflow pathway  702  from the rear edge  710  of the cutting blade  114  out through the dust extraction port  722 . Similar to what is shown in  FIG. 6 , the shoe member  718  can be moved relative to the housing  704  and can establish and maintain the dust extraction airflow  700  through the airflow pathway  702  in any of the cutting angles  116  ( FIG. 6 ). 
     In one example, an adapter member  726  can connect the dust extraction port  722  to the vacuum source  724 . The adapter member  726  can be configured as a component that can releaseably couple to the dust extraction port  722  and/or the vacuum source  724  or can be integral or fixedly coupled to the dust extraction port  722  and/or the vacuum source  724 . 
     With reference to  FIG. 11 , a dust extraction airflow  750  can be directed through an airflow pathway  752  formed in an exemplary housing  754  of a jigsaw  756 . It will be appreciated in light of the disclosure that the dust extraction airflow  750  through the airflow pathway  752  can be implemented on the jigsaw  100  ( FIG. 1 ). In this regard, a portion (or all) of the dust extraction airflow  750  can be directed through an angle indicator wheel  758 , which can be similar to the angle indicator wheel  128  ( FIG. 1 ). 
     In one example, the dust extraction airflow  750  can begin at a rear edge  760  of the cutting blade  114 . The dust extraction airflow  750  can continue up through an air scoop member  762  and into multiple ribs  764  formed in the housing  754  that can establish the airflow pathway  752 . The airflow pathway  752  can continue through the housing  754 , above a shoe block member  766  toward a rear portion  768  of the housing  754 . The dust extraction airflow  750  in the airflow pathway  752  can turn downward toward a shoe member  770  and can be directed through an inner periphery  772  of the angle indicator wheel  758 . The airflow pathway  752  can move through the angle indicator wheel  758  and out through a dust extraction port  774  formed in the rear portion  768  of the housing  754 . 
     A vacuum source  776  can attach to the dust extraction port  774  formed in the housing  754  to establish the dust extraction airflow  750  from the rear edge  760  of the cutting blade  114  out through the dust extraction port  774 . Similar to what is shown in  FIG. 6 , the shoe member  770  can be moved relative to the housing  754  that can establish the airflow pathway  752  in any of the cutting angles  116  ( FIG. 6 ). 
     It will be appreciated in light of the disclosure that the vacuum source  138 ,  234 ,  428 ,  528 ,  724 ,  776  can be one or more of a canister vacuum, central vacuum system, dust collection system or the like. In one example, an adapter member  778  can connect the dust extraction port  774  to the vacuum source  776 . The adapter member  778  can be configured as a component that can releaseably couple to the dust extraction port  774  and/or the vacuum source  776  or can be integral or fixedly coupled to the dust extraction port  774  and/or the vacuum source  776 . 
     With reference to  FIG. 12 , the scoop member  148  can be positioned behind an upper carrier assembly  150  that is configured to support the cutting blade  114 . Behind the scoop member  148 , the shoe member  120  can be secured to the bottom  122  of the housing  102 . The scoop member  148  can establish a front lip  152  that can extend toward the cutting area  142 . From the front lip  152 , two arcuate side wall members  154  can extend upward toward the housing  102 . 
     In one example, the arcuate side wall members  154  and the front lip  152  can be configured as a component that can releaseably couple to the housing  102  or can be integral or fixedly coupled to the housing  102 . The dust extraction airflow  140  can enter through the scoop member  148  and travel from the scoop member  148  through the housing  102  (e.g., through the airflow pathway  752  in  FIG. 11 ) to be exhausted from the dust extraction port  134  ( FIG. 1 ). 
     With reference to  FIGS. 13, 14 and 15 , a shoe subassembly  800  includes a shoe member  802 , a shoe block member  804  and a bevel lever  806 . The bevel lever  806  can be attached to the shoe block member  804  with a fastener  808  that can include a spring  810  to provide tension to the bevel lever  806 , especially in the locked condition. In one example, the spring  810  can be omitted. 
     A clamp member  812  can be connected to a bottom surface  814  of the shoe member  802  with a fastener  816 . In another example, the clamp member  812  can be configured as a component that can releaseably couple to the shoe member  802  or can be integral or fixedly coupled to the shoe member  802 . A head  818  of the fastener  808  can be received in an aperture  820  formed in the clamp member  812 . A threaded end  822  of the fastener  808  can be received by a threaded member  824  that can be fixed to the bevel lever  806 . 
     Posts  826  that each can extend from the shoe block member  804  can extend through grooves  828  formed on the shoe member  802  and grooves  830  on the clamp member  812 . The fastener  808  can also pass through a groove  832  formed on the shoe member  802 . The groove  828 , the groove  830  and/or the groove  832  can be used to align the shoe member  802 , the shoe block member  804  and the clamp member  812 . The threaded member  824  can be configured to be fixed coupled to or integral with the bevel lever  806 . 
     Similar to the bevel lever  132  in  FIG. 1 , the bevel lever  806  can be moved between the locked condition and the unlocked condition. When moving from the unlocked condition to the locked condition, the bevel lever  806  moves the threaded member  824  to draw the fastener  808  upward (i.e., toward the top of the page in  FIG. 15 ). By drawing the fastener  808  upward, a clamping force between the clamp member  812  and the shoe block member  804  on the shoe member  802  can be increased. In the locked condition, the clamping force between the clamp member  812  and the shoe block member  804  is sufficient to prevent the pivoting of the shoe member  802 . As the bevel lever  806  is moved from the unlocked condition to the locked condition, the movement of the threaded member  824  with the bevel lever  806  can push the fastener  808  downward. By pushing the fastener  808  downward, the clamping force can be sufficiently reduced to a value such that the shoe member  802  can pivot relative to the shoe block member  804  and ultimately a housing of a jigsaw to which the shoe block member  804  can be attached, e.g., the jigsaw  100  ( FIG. 1 ). 
     With reference to  FIG. 14 , an interaction member  850  can secure to and can extend from the shoe block member  804 . The interaction member  850  can contact a first row of partial gear teeth  852  formed on a shoe insert  854  that can be coupled to the shoe member  802 . The first row of partial gear teeth  852  can be adjacent a second row of partial gear teeth  856 . The shoe insert  854  can be formed of a flexible material so as to permit the bending of the shoe insert  854  into a curved channel  858  ( FIG. 13 ) formed in the shoe member  802 . 
     The first row of partial gear teeth  852  can selectively contact the interaction member  850  that extends from the shoe block member  804 . The second row of partial gear teeth  856  can mesh with partial gear teeth  860  formed on an angle indicator wheel  862  ( FIG. 13 ). In one example, one or more intermediate gears (whole or partial) can be disposed between a shoe member and an indicator wheel so that pivoting the shoe member relative to a jigsaw housing can rotate the one or more intermediate gears and the indicator wheel. 
     The interaction member  850  that extends from the shoe block member  804  can provide a momentary positive lock between the shoe block member  804  and the shoe member  802  via engagement between the interaction member  850  and the first row of partial gear teeth  852 . As the shoe member  802  is pivoted relative to the shoe block member  804 , the interaction member  850  can deflect and jump from each of the pockets  864  formed between gear teeth  866  in the first row of partial gear teeth  852 . 
     In one example, the interaction member  850  can be a leaf spring  868  that can connect to the shoe block member  804 . The deflection of the leaf spring  868 , as a portion of the leaf spring  868  jumps between the pockets  864  formed between the gear teeth  866 , can provide an audible click. The audible click can be an indicator to a user that the shoe member  802  has pivoted to the next angular detent, e.g., a move from the fifteen degree cutting angle  352  ( FIG. 6 ) to a thirty degree cutting angle. In a further example, a spring biased member, such as a ball, post, etc., can similarly interact with the pocket  864  of the gear teeth  866 . The spring biased member can be coupled to the shoe block member  804  and extend toward the shoe insert  854 . 
     The shoe subassembly  800  can be assembled, as illustrated in  FIG. 14 , prior to fully assembling the jigsaw, which, for example, can be the jigsaw  100 ,  200 ,  300  ( FIGS. 1, 2 and 3 ). In addition, a locking mechanism  870  ( FIG. 14 ) can be configured so that the shoe clamping force for the locking mechanism  130 ,  226 ,  870  ( FIGS. 1, 2 and 15 ) can be set and configured prior to assembling the shoe subassembly  800  with the jigsaw housings  102 ,  202 ,  302 . In one example, the shoe clamping force can be set so that a range of shoe clamping force values is selectively available to the user, as the user manipulates the locking mechanism  130 ,  226 ,  870  ( FIGS. 1, 2 and 15 ) between the locked and unlocked conditions. The range of clamping force values can be set, thus predetermined, by selecting a distance  872  from the head  818  of the fastener  808  and the threaded member  824  on the bevel lever  806 . It will be appreciated in light of the disclosure that the shoe subassembly  800  can be assembled, the clamping force can be set and the shoe subassembly  800  can be shipped from a location other than in a location where the jigsaw is assembled. 
     With reference to  FIG. 16 , the shoe insert  854  having the two rows of partial gear teeth  852 ,  856  ( FIG. 14 ) can be assembled into the shoe member  802 , which can be separately manufactured from the shoe insert  854 . The shoe insert  854 , as a separate component, can include the relatively complex structure detailed geometry of the first and second partial rows of gear teeth  852 ,  856 . The fabrication of such relatively complex structures, in certain instances, is not required when fabricating the shoe member  802 . 
     With reference to  FIG. 17 , a shoe insert  874  having the two rows of partial gear teeth  852 ,  856  ( FIG. 14 ) can be produced with a shoe member  876  that can be monolithically manufactured together with the shoe insert  874 . In one example, the shoe insert  874  and the shoe member  876  are all one piece of metal. While in another example, the shoe insert  854  can be manufactured separately but can be cast in place or mechanically or chemically fastened to the shoe member  876 . In the above examples, the shoe insert  874  need not be flexible. 
     With reference to  FIG. 18 , a flowchart method of inserting the shoe insert  854  ( FIG. 16 ) into the shoe member  802  ( FIG. 16 ) generally includes, at  880 , providing a shoe member  802  that defines a curved channel  858  ( FIG. 13 ) and providing a shoe insert  854  configured to be accepted by the curved channel  858 . At  882 , a first end  884  ( FIG. 16 ) of the shoe insert  854  can abut a first end  886  ( FIG. 16 ) of the curved channel  858 . At  888 , at least a portion of the shoe insert  854  can be bent, flexed or otherwise distorted by a user  890  ( FIG. 16 ). At  892 , a second end  894  ( FIG. 16 ) of the shoe insert  854  can be aligned with a second end  896  ( FIG. 16 ) of the curve channel  858 . At  898 , the shoe insert  854  can be released from the bending or flexing at  888 . After  898 , the method can end. 
     With reference to  FIGS. 19 and 20 , an exemplary shoe member  900  is shown with portions of a housing  902  (and in some examples a shoe block member  904 ) visible through the shoe member  900 . As such, a bottom  906  of the housing  902  can define stop members  908  that can interact with a complementary pocket  910  formed in channels  912  in the shoe member  900 . In an example where the shoe block member  904  is implemented, the shoe block member  904  can connect to the housing  902  and the stop members  908  can extend from the shoe block member  904 . 
     In one example, one or more of the stop members  908  can have a wedge shape and the pockets  910  can have a complementary wedge shape. In a further example, the stop members  908  can have a circular shape and the pockets  910  can have a complementary circular shape. When the shoe member  900  is positioned at a zero degree angular position (i.e., a perpendicular cutting angle), the shoe member  900  can be advanced in a direction  914  that can be axially backward relative to a cutting direction  916  (i.e., toward the right side of the page in  FIG. 19 ) to engage the stop members  908  that extend from the housing  902 . In this regard, the stop members  908  can move into complimentary pockets  910  and can provide a positive engagement at zero degrees. 
     Because of the wedge shape of the stop members  908 , the complementary pockets  910  can be axially advanced onto the wedge shaped stop members  908 . When there is any slack (i.e., gaps) in the contact between the stop members  908  and the complementary pockets  910 , additionally advancing the shoe member  900  so that the complementary pockets  910  receive more and more of the wedge shaped stop members  908 , can further close any gaps relative to a configuration of stop members not having the wedge shape but having parallel sides. In contrast, the stop members  908  having the wedge shape, can define walls  918  ( FIG. 20 ) that converge toward the cutting direction  916  of the jigsaw, i.e., toward the left in  FIG. 1 . 
     By taking up the other tolerances in the shoe subassembly  800  ( FIG. 14 ), other tolerances in the shoe subassembly  800  do not need to be held as tight as would otherwise be without the wedge shaped stop members  908  that extend from the housing  902  or shoe block member  804 . It will be appreciated in light of the disclosure that the shoe member  900  and the above described shoe subassembly  800  can be implemented on any of the jigsaws  100 ,  200 ,  300 ,  400 ,  500 , above. 
     With reference to  FIG. 20 , the shoe member  900  is shown in a position other than zero degrees (e.g., the cutting angle  354  ( FIG. 6 )). In this instance, the wedge shaped stop members  908  cannot be received within the wedge shaped pockets  910  formed in the shoe member  900  but advance along the channels  912  that contain pockets  910  as the shoe member pivots relative the housing  902 . It will be appreciated in light of the disclosure that stop members  908  can extend from the housing  902  (or the shoe block member  904 ) at other angular positions (i.e., not at zero degrees) so that the shoe member  900  can be axially moved relative to housing  902  to provide positive engagement at one or more cutting angles. For example, stop members can be provided for positive engagement of the shoe member  900  at zero degrees and at forty-five degrees. In other examples, stop members can be provided for positive engagement of the shoe member  900  at only forty-five degrees. 
     With reference to  FIG. 21 , another example shoe member  950  is shown with portions of a housing  952  (or a shoe block member  954 ) visible through the shoe member  950 . As such, a bottom of the housing  952  can define stop members  956  that can interact with complimentary pockets  958  formed in channels  962  the shoe member  950 . The shape of the stop members  956  and/or the pockets  958  can be similar to the stop members  908  and complimentary pockets  910  illustrated in  FIGS. 19 and 20 . The shoe member  950 , however, can be positioned at a zero degree angular position and can be advanced in a direction  960  that can be axially forward relative to (i.e., in line with) the cutting direction  916  engage the stop members  956  that extend from the housing  952 . In this regard, the motion of the shoe member  950  can be similar to that of the shoe member  902  and  FIG. 19 , but can be moved in direction  960 , in contrast to direction  914  ( FIG. 19 ).
