TECHNICAL FIELD

The present disclosure generally relates to a multipurpose tool. More particularly, the present disclosure relates to a portable angle drilling table. Specifically, the present disclosure relates to a portable angle drilling table that is useable to enable a user to more accurately use a drill press to drill a hole into a workpiece at compound angles without adjusting a table of the drill press.

BACKGROUND

Drill presses are versatile tools which are used in multiple projects for drilling holes into different types of workpiece, such as wood workpiece. Generally, drill presses are used in woodworking projects for drilling and/or boring substantially vertical holes of different dimensions based on the selected drilling bit used with a selected drill press. While a woodworker may use a drill press to drill various types of holes in workpiece, it is difficult and demanding to drill precise and accurate holes into a workpiece where the holes are to be drilled at more than one angle (i.e., compound angles).

Generally, the woodworker may simply adjust the table of the drill press to combat these angles. While such adjusting is viable, the woodworker may have to periodically adjust the table of the drill press at various angles to complete a single woodworking project. Such continuous adjustment during a single woodworking project requires the expenditure of more time and effort when the woodworker is drilling multiple holes into a workpiece or into numerous types of workpiece. Such continuous adjustment during a single woodworking project may also create inaccurate drilling of holes into a workpiece due to the constant expenditure of manipulating and leveling the table of the drill press during woodworking projects.

To combat these issues, a woodworker may select a device or multiple devices to help drill at at least one suitable angle during a drilling operation. While such assisting devices are provided in the market, the woodworker may have to use a number of different devices to drill different precise holes into a workpiece at more than one angle. For example, the woodworker may have to use a first set of assisting devices with a drill press for drilling a first hole with a first set of dimensions (e.g., a first compound angle) and a second set of assisting devices with the drill press for drilling a second hole with a second set of dimensions (e.g., a second different compound angle). Such use of multiple assisting devices requires the woodworker to have access to these various assisting devices and requires the expenditure of more time and effort when the woodworker is drilling multiple holes into a workpiece.

SUMMARY

The presently disclosed machining jig provides a woodworker with a multifunctional tool which may be used for adjusting and aligning a workpiece with a drill bit of a drill press in order to make at least one hole at at least one desired compound angle in a workpiece. The disclosed machining jig eliminates the step of a woodworker readjusting and/or reorienting a table of a drill press to complete a project and reduces the project's completion time since the need to readjust the table of the drill press is avoided.

The sacrificial insert26enables a woodworker to drill into the machining jig1with the drill press or drilling device while not damaging the work table14. In the illustrated embodiment, the sacrificial insert26is made of wood material which will not further damage or dull a drilling bit operatively engaged with a drill press during drilling operations. During drilling operations, a woodworker may remove and replace the sacrificial insert26with another new sacrificial insert when the previous sacrificial insert26no longer provides structural support to a workpiece. During other drilling operations, a woodworker may remove the sacrificial insert26from the work table14to allow the work table14to hold a rounded or curvilinear-shaped workpiece via the V-shaped groove14M (seeFIG.14B).

As described above, the attachment plates28operably engage with the work table14to hold the sacrificial insert26with the work table14. The attachment plates28also hold the sacrificial insert26flush with outer surface14E of the work table14. Each attachment plate28defines a set of first attachment holes28A that extends entirely through each attachment plate28to allow a set of attachment mechanisms29(e.g., connectors threadably engaging with nuts) to operably engage the attachment plate28with the work table14below the central opening14N (seeFIG.14B). Specifically, each connector29A of the attachment mechanisms29operably engages with a respective attachment plate28and threadably engages with a nut29B inside of the at least one inner channel14H of the work table14.

Referring toFIG.14A, each attachment plate28also defines a set of second attachment holes28B that extends entirely through each attachment plate28to allow a set of fasteners (e.g., screws and other components of the like) (not illustrated) to operably engage the sacrificial insert26with the attachment plates28.

Referring toFIG.3, the machining jig1includes an adjustment assembly30. The adjustment assembly30operably engages with the base table12and the work table14to enable the work table14to be selectively pivotably adjustable to a desired angle from a range of predetermined angles relative to the base table12. The woodworker will decide at what angle to set the work table14to relative to the base table12and will then utilize the adjustment assembly30to set the work table14at the desired selected angle. Additionally, the adjustment assembly30is configured to secure the work table14and the base table12to one another at a predetermined angle determined by the woodworker during a drilling project.

Still referring toFIG.3, the adjustment assembly30includes a protractor plate32. The protractor plate32has a first end or top end32A and a second end or bottom end32B opposite to the top end32A. The protractor plate32defines a set of attachment openings32C proximate to the top end32A of the protractor plate32. Each attachment opening or the set of attachment openings32C extends entirely through the protractor plate32; such use and purpose of the set of attachment openings32C is described in more detail below. The protractor plate32also defines a curvilinear or arcuate slot32D that arcuately extends between the top end32A and the bottom end32B and is defined vertically below the set of attachment openings32C; such use and purpose of the set of attachment openings32C is described in more detail below.

Still referring toFIG.3, the protractor plate32also includes a set of indexing teeth32E that extends away from an outermost end32F of the protractor plate32. As illustrated herein, the set of indexing teeth32E is positioned adjacent to the arcuate slot32D. The protractor plate32also has a set of angle indicia32G that defines a range of angles for enabling the work table14to be set a predetermined angle relative to the base table12, which is described in more detail below. In the illustrated embodiment, set of angle indicia32G defines a range of angles from about zero degree up to about ninety degrees for pivotably adjusting the work table14relative to the base table12. In the illustrated embodiment, each tooth of the set of indexing teeth32E is arranged at one angle increments where each tooth of the set of indexing teeth32E defines an angle from the range of angles set by the set of angle indicia32G. Such use and operation of the protractor plate32is described in more detail below.

Still referring toFIG.3, the adjustment assembly30also includes a selector34. The selector34has a first end or front end34A and a second end or rear end34B opposite to the front end34A. The selector34defines a set of securement openings34C between the front end34A and the rear end34B. Each securement opening of the set of securement openings34C that extends entirely through the selector34; such use and purpose of the set of securement openings34C is described in more detail below. A first securement opening34C1of the set of securement openings34C is defined proximate to the front end34A, and a second securement opening34C2of the set of securement openings34C is defined proximate to the rear end34B opposite to the first securement opening34C1. The selector34also defines a handle34D that extends from the rear end34B towards the front end34A. The handle34D of the selector34enables a woodworker to longitudinally move the selector34along the base table12when operably engaged with said base table12, which is described in more detail below.

Still referring toFIG.3, the selector34also includes a set of selecting teeth34E. The set of selecting teeth34E extends radially away from the front end34A of the selector34. As illustrated herein, the set of selecting teeth34E is complementary to the set of indexing teeth32E of the protractor plate32. As described in more detail below, the complementary arrangement between the set of indexing teeth32E and the set of selecting teeth34E allows the set of selecting teeth34E of the selector34to operably meshes with the set of indexing teeth32E of the protractor plate32to maintain the work table14at a predetermined angle relative to the base table12(seeFIG.10C). In other words, the set of selecting teeth34E enables a woodworker to index the protractor plate32at a predetermined angle to maintain the work table14at said predetermined angle relative to the base table12.

Still referring toFIG.3, the adjustment assembly30also includes an indicator36. The indicator36includes a first end or front end36A and a second end or rear end36B opposite to the front end36A.

The indicator36also includes a pointer36D that is positioned proximate to the front end36A of the indicator36. The pointer36D enables a woodworker to align the pointer36D with a desired angle from the set of angle indicia32G so that the protractor plate32and the selector34mesh at the desired angle to maintain the work table14at said desired angle relative to the base table12. Additionally, the indicator36is made from a transparent material and/or a material to enable a woodworker to see through the indicator36when selecting a desired angle and indexing the set of selecting teeth34E of the selector34with the set of indexing teeth32E of the protractor plate32.

Still referring toFIG.3, the adjustment assembly30also includes connecting mechanisms38to operably engage the protractor plate32with the work table14. Each connecting mechanism38includes a threaded connector38A that operably engages with a nut38B to operably engage the protractor plate32with the work table14. Specifically, the threaded connector38A of each connecting mechanism38threadably engages with the nut38B of each connecting mechanism38inside of the first side channel14J of the work table14to operably engage the protractor plate32with the work table14. Additionally, each connecting mechanism38may include a washer38C that operably engages with the threaded connector38A and is positioned between the protractor plate32and the work table14. This structural configuration enables a woodworker to selectively adjust the work table14at a particular angle via the set of angle indicia32G provided on the protractor plate32.

Still referring toFIG.3, the adjustment assembly30also includes adjustable lever mechanisms40to operably engage the protractor plate32, the selector34, and the indicator36to the base table12when the adjustable lever mechanisms40are provided in tightened positions. The adjustable lever mechanisms40also allow the protractor plate32and the selector34to be moveable relative to the base table12when the adjustable lever mechanisms40are provided in loosened positions (i.e., disengaged from the protractor plate32and the selector34while still be operably engaged with the base table12and the work table14).

Still referring toFIG.3, each adjustable lever mechanism40includes a threaded handle40A that threadably engages with a nut40B inside of the first side channel12J of the base table12to operably engage the protractor plate32and the selector34with the work table14. Each adjustable lever mechanism40also includes a bushing40C that operably engages with the threaded handle40A and is positioned between the threaded handle40A and one of the protractor plate32and the selector34. Each adjustable lever mechanism40also includes a washer40D that operably engages with the threaded handle40A and is positioned between the base table12and one of the protractor plate32and the selector34. As illustrated inFIG.1A, a first adjustable lever mechanism40operably engages with the protractor plate32via the curvilinear slot32D, and a second adjustable lever mechanism40operably engages with the selector34via the first securement opening34C1of the set of securement openings34C and the indicator via the first mounting opening36C1of the set of mounting openings36C1. In the loosened position, the work table14and the protractor plate32are enabled to collectively pivot, via the at least one hinge22, upwardly away from the first adjustable lever mechanism40(seeFIG.10A). In the loosened position, the selector34is able to longitudinally move along the base table12so the selector34is disengaged from the protractor plate32at a distance away from said protractor plate32(seeFIG.10A). In the tightened position, the work table14and the protractor plate32are collectively maintained at a desired angle relative to the base table12(seeFIG.10C). In the tightened position, the selector34is maintain and is unable to longitudinally move along the base table12so the selector34remains engaged with the protractor plate32to maintain the work table14and the protractor plate32at the desired angle relative to the base table12(seeFIG.10C).

Still referring toFIG.3, the adjustment assembly30includes a locking mechanism44that operably engages the selector34and the indicator36to the base table12.

The locking mechanism44may include a washer44E that operably engages with the bolt44A and is positioned between the selector34and the base table12.

Referring toFIG.8, the machining jig1also includes a locking plate assembly46operably engaged with the base table12and the work table14at a position opposite to the adjustment assembly30relative to the transverse axis of the machining jig1. Similar to the adjustment assembly30, the locking plate assembly46is configured to maintain the work table14at a desired angle relative to the base table12. The locking plate assembly46also enables a woodworker to adjust the work table14at any desired angle from a range of angles offered by the locking plate assembly46; the range of angles provided by the locking plate assembly46is substantially similar to the range of angles provided by the adjustment assembly30. During woodworking projects, a woodworker may be enabled to use one or both of the adjustment assembly30and the locking plate assembly46. In one instance, one of the adjustment assembly30and the locking plate assembly46may be used to maintain the work table14at a desired angle relative to the base table12. In another instance, the adjustment assembly30and the locking plate assembly46may be collectively used to maintain the work table14at a desired angle relative to the base table12. Such use and operation of the locking plate assembly46is described in more detail below.

Referring toFIG.8, the locking plate assembly46includes a locking plate48substantially similar to the protractor plate32of the adjustment assembly30. The locking plate48has a first end or top end48A and a second end or bottom end48B opposite to the top end48A. The locking plate48defines a set of attachment openings48C proximate to the top end48A of the locking plate48.

In the loosened position, the work table14and the locking plate48are collectively moveable where the work table14and the locking plate48may be pivoted upwardly via the at least one hinge22. In this position, the adjustable lever mechanism49B is disengaged from the locking plate48while still being engaged with the base table12. In the tightened position, the work table14and the locking plate48are collectively moveable where the work table14and the locking plate48are maintained at a desired angle relative to the base table12. In this position, the adjustable lever mechanism49B is engaged with the locking plate48to prevent movement of the locking plate48and the work table14relative to the base table12.

The machining jig1may include a fence assembly60that operably engages with the work table14. The fence assembly60is configured to provide additional support for the woodworker when a workpiece is introduced to the work table14. In one instance, the fence assembly60may directly abut a straight edge of a workpiece to prevent said workpiece from shifting or rotating when a drill press drills a hole into said workpiece. In another instance, the fence assembly60may be used with additional woodworking tools and/or components for maintaining a workpiece on the work table14of the machining jig1during woodworking projects; such use of additional woodworking tools and/or components with the fence assembly60is described in more detail below.

As illustrated inFIG.4, the fence assembly60includes a fence62. The fence62includes a first or front end62A, a second or rear end62B that is opposite to the front end62A, and a longitudinal axis defined therebetween. The fence62includes a plate62C that extends from the front end62A to the rear end62B along the longitudinal axis. The plate62C defines an attachment opening62D at a location between the front and rear ends62A,62B proximate to the front end62A. The attachment opening62D also extends entirely through the plate62C. The plate62C also defines an attachment slot62E at a location between the front and rear end62A,6B proximate to the rear end62B. The attachment slot62E also extends entirely through the plate62C. Such uses and purposes of the attachment opening62D and the attachment slot62E are described in more detail below.

Still referring toFIG.4, the fence62also includes a first rail62F that extends upwardly from the plate62C and is positioned between the front end62A and the rear end62B of the fence62. During woodworking projects, the first rail62F and the plate62C may operably engage a first outermost end of a workpiece when said workpiece is introduced to the machining jig1(seeFIG.12A). The fence62also includes a second rail62G that extends upwardly from the plate62C and is positioned between the front end62A and the rear end62B of the fence62(seeFIG.12A). The second rail62G is positioned adjacent to the first rail62F relative to a transverse axis of the fence62. The first rail62F and the second rail62G collectively define a T-shaped channel62H that extends along the entire length of the fence62from the front end62A to the rear end62B. Such uses and purposes of the first rail62F and the second rail62G are described in more detail below.

Still referring toFIG.4, the fence assembly60also includes at least one flip stop64that operably engages with the fence62. Specifically, the at least one flip stop64operably engages with the first rail62F and the second rail62G on the fence62where the at least one flip stop64is moveable along the first rail62F and the second rail62G, which is described in more detail below. The at least one flip stop64is configured to operably engage a second outermost end of the workpiece that is orthogonal to the first outermost end of the workpiece operably engaged with the plate62C and the second rail62G (seeFIG.12A). In the illustrated embodiment, a single flip stop64is provided in the fence assembly60. The flip stop64may also be omitted from the fence assembly60if desired by a woodworker based on the woodworking project (e.g., the size, shape, or configuration of a workpiece, the types of woodworking tools and/or components used with the fence, and other suitable workpiece characteristics of the like).

Still referring toFIG.4, the flip stop64includes a housing64A. The housing64A defines a through-hole64B that extends entirely through the housing64A along a vertical axis of the housing64A. The flip stop64also includes a stop arm64C that operably engages with the housing64A via a connector64D. The stop arm64C is rotatable about the longitudinal axis of the connector64D between an up position and a down position. In the up position, the stop arm64C is rotated upwardly away from the fence62where the stop arm64C is free from contacting or engaging a workpiece. In the down position, the stop arm64is rotated downwardly towards the fence62where the stop arm64C contacts and engages the second outermost end of the workpiece (seeFIG.12A).

Still referring toFIG.4, the fence assembly60includes a connecting mechanism66that operably engages the flip stop64with the fence62. Specifically, the connecting mechanism66operably engages the housing64A of the flip stop64with the first and second rails62F,62G of the fence62. The connecting mechanism66includes a bolt66A that threadably engaged with a thumb nut66B to operably engage the flip stop64to the fence62. Once assembled, the head of the bolt66A operably engages with the first rail62F and the second rail62G inside of the T-shaped channel62H. The shaft of the bolt66A passes through the T-shaped channel62H and the flip stop64(via the through-hole64B) which then operably engages with the thumb nut66B. During woodworking projects, a woodworker may loosen the thumb nut66B from the bolt66A to enable the woodworker to move the flip stop64to a desired position on the first and second rails62F,62G while the flip stop64is still operably engaged with the first and second rails62F,62G. The woodworker may then tighten the thumb nut66B to the bolt66A until the flip stop64is secured to the first and second rails62F,62G.

Still referring toFIG.4, the fence assembly60includes adjustable lever mechanisms68that are substantially similar to the adjustable lever mechanism described and illustrated herein (e.g., adjustable lever mechanisms40,49B). Each adjustable lever mechanism68includes a threaded handle68A that threadably engages with a nut68C inside of one of the outer channels14G of the work table14to operably engage the fence62with the work table14. Each adjustable lever mechanism68also includes a nut68C that operably engages with the threaded handle68A and is positioned between the threaded handle68A and the fence62. The adjustable lever mechanisms68operably engages the fence62with the work table14via the attachment opening62D and the attachment slot62E of the fence62and at least one outer channel14G of the work table14.

During woodworking projects, a woodworker may engage the adjustable lever mechanism68with at least one outer channel14G where the fence62may be arranged in various orientations on the work table14based on various considerations, including the size, shape, and configuration of the workpiece, the angle of drilling a hole into a workpiece, and other various considerations of the like. In one instance, the adjustable lever mechanisms68may be operably engaged in a single outer channel14G of the work table14(such as the first outer channel14G1) where the fence62is aligned parallel with the single outer channel14G and the longitudinal axis of the machining jig1(seeFIGS.1A and11). In another instance, a first adjustable lever mechanism68may be operably engaged with work table14inside of the first outer channel14G1and a second adjustable lever mechanism68may be operably engaged with the work table14inside of the second outer channel14G2. In this instance, the fence62may be oriented orthogonal to the first and second outer channels14G1,14G2or may be oriented to a desired angle on the work table14via the angle scale18. Such operation of the fence assembly60with the work table14is described in more detail below.

Referring toFIG.1B, the machining jig1may also include a clamping system80. The clamping system80may include at least one or more components and/or devices for clamping and securing a workpiece to the machining jig1for drilling purposes. Specifically, at least one or more components and/or devices of the clamping system80may be used for clamping and securing a workpiece to the work table14of the machining jig1. As described in more detail below, any suitable number of components and devices of the clamping system80may be used with together for clamping and securing a workpiece to the work table14of the machining jig1.

Still referring toFIG.1B, the clamping system80includes a fixed wedge82. As described in more detail below, the fixed wedge82operably engages with the work table14at a desired fixed position. The fixed wedge82includes a first or front end82A and a second or rear end82B that is opposite to the front end82A. The fixed wedge82also has a tapered wall82C that extends between the front end82A and the rear end82B. The tapered wall82C tapers inwardly as the tapered wall82C extends from the front end82A to the rear end82B. Such use and purpose of the tapered wall82C is described in more detail below.

Still referring toFIG.1B, the fixed wedge82also defines a set of first attachment openings82D that extend entirely through the fixed wedge82. The set of first attachment openings82D are defined proximate to the front end82A of the fixed wedge82; such use and purpose of the set of first attachment openings82D is described in more detail below. The fixed wedge82also defines a set of second attachment openings82E that extend entirely through the fixed wedge82. The set of second attachment openings82E are defined diagonally along the fixed wedge between the front end82A and the second end82B of the fixed wedge82; such use and purpose of the set of second attachment openings82E is described in more detail below.

Still referring toFIG.1B, the clamping system80also includes at least one fly nut mechanism84. The at least one fly nut mechanism84operably engages the fixed wedge82with the work table14at a desired fixed position via one of the set of first attachment openings82D and the set of second attachment openings82E. In the illustrated embodiment, the clamping system80includes two fly nut mechanisms84for operably engaging the fixed wedge82with the work table14at the desired fixed position.

The at least one fly nut mechanism84has a fly nut84A that threadably engages with a bolt84B. As illustrated inFIG.12B, the bolt84B of the at least one fly nut mechanism84operably engages the fixed wedge82with the work table14. Specifically, the bolt84B operably engages the fixed wedge82inside an attachment opening of the set of first attachment openings82D or the set of second attachment openings82E, and the head of the bolt84B is configured to operably engaged with the work table14inside of the at least one outer channel14G (specifically with the upper wall14G′ of the at least one outer channel14G). The fly nut84A of the at least one fly nut mechanism84threadably engages with bolt84B to secure the bolt84B to a desired fixed position with the work table14(seeFIG.12B). Such use and operation of the at least one fly nut mechanism84is discussed in more detail below.

The clamping system80also includes a moveable wedge86. As described in more detail below, the moveable wedge86operably engages with the fixed wedge82at the desired fixed position by wedging and/or jamming the moveable wedge86between the fixed wedge82and a workpiece (seeFIG.12B). Such interaction between the fixed wedge82and the moveable wedge86secures the workpiece on the work table14in combination with a fence assembly (e.g., fence assembly60), which is also described in more detail below.

Still referring toFIG.1B, the moveable wedge86includes a first or front end86A and a second or rear end86B that is opposite to the front end86A. The moveable wedge86also has a tapered wall86C that extends between the front end86A and the rear end86B. The tapered wall86C tapers inwardly as the tapered wall86C extends from the rear end86B to the front end86A. The tapered wall86C of the moveable wedge86is configured to operably engage with the tapered wall82C of the fixed wedge82for enabling a woodworker to secure a workpiece between the fence62of the fence assembly60and the movable wedge86of the clamping system80via a wedging and/or jamming force (seeFIG.12B). The moveable wedge86also has a planar or straight wall86D that is positioned opposite to the tapered wall86C. The planar wall86D extends between the front end86A and the rear end86B. The planar wall86D is configured to operably engage with an outermost end of a workpiece that is also substantially planar and/or straight.

The structural configuration between the fixed wedge82and the moveable wedge86on a work table14is considered advantageous at least because this configuration enables a woodworker to hammer and/or strike the moveable wedge86between the workpiece and the fixed wedge82until the tapered walls82C,86C restrict the movement of the moveable wedge86along the fixed wedge82. The configuration of the fixed wedge82and the moveable wedge86also is considered advantageous at least because this configuration enables a woodworker to secure various types of workpiece to the work table14without rearranging and/or reconfiguring the machining jig1between woodworking project; as such, the moveable wedge86may be the only tool and/or component that is be readjusted between each woodworking projects.

The clamping system80may also include at least one pivot clamp87. The at least one pivot clamp87is configured to operably engaged with the work table14to clamp and secure various types of workpiece to said work table14. Specifically, the at least one pivot clamp87is configured to operably engage with a surface of a workpiece for clamping and securing said workpiece to the work table14. The at least one pivot clamp87is also configured to be pivotably moveable on the work table14once operably engaged with the work table14; such pivot movement of the at least one pivot clamp87is described in more detail below.

Referring toFIG.1B, the at least one pivot clamp87includes a pivot plate88that has a first end88A, a second end88B opposite to the first end88A, and a longitudinal axis defined therebetween. The pivot plate88also includes a first clamp portion88C that extends from the first end88A towards the second end88B with a first length “L1”. The pivot plate88also includes a second clamp portion88D that extends from the first clamp portion88C to the second end88B with a second length “L2”; the first length “L1” of the first clamp portion88C is greater than the second length “L2” of the second clamp portion88D. As illustrated inFIG.1B, the pivot plate88defines a bend88E that differentiates the first clamp portion88C and the second clamp portion88D from one another. As such, the bend88E orients the first clamp portion88C at an angle relative to the second clamp portion88D. Such angle created by the bend88E allows the pivot plate88to provide downwardly clamping force onto a surface of a workpiece during woodworking projects; such clamping force of the pivot plate88is described in more detail below.

Still referring toFIG.1B, the pivot plate88also defines a cavity88F at the bend88E and between the first clamp portion88C and the second clamp portion88D; such use of cavity88F is described in more detail below. The cavity88F is also defined along an axis that is orthogonal to the longitudinal axis of the pivot plate88. The pivot plate88also defines a slit88G at the bend88E and between the first clamp portion88C and the second clamp portion88D; such use of the slit88G is also described in more detail below. The slit88G is defined along an axis that is parallel with the longitudinal axis of the pivot plate88and orthogonal to the cavity88F. The cavity88F and the slit88G intersect one another and are in fluid communication with one another.

Still referring toFIG.1B, the pivot plate88also includes a first cover88H1that operably engages with the first clamp portion88C at the first end88A. The pivot plate88also includes a second cover88H2that operably engages with the second clamp portion88D at the second end88B. The first and second covers88H1,88H2may provide additional grip for the pivot plate88when clamping and securing a workpiece to the work table14. The first and second covers88H1,88H2may also prevent marring or damage to the workpiece and/or the work table14when the pivot plate88clamps and secures said workpiece to the work table14.

The clamping system80also includes at least one locking knob assembly90that operably engages with the pivot plate88. In the illustrated embodiment, a single locking knob assembly90operably engages with a single pivot plate88. The locking knob assembly90is configured to operably engage the pivot plate88with the work table14for clamping and securing a workpiece to the work table14. Upon assembly, the locking knob assembly90is configured to be provided between a loosened position and a tightened position for enabling and restricting movement of the pivot plate88on the work table14. As such, the locking knob assembly90allows the pivot plate88to pivot and/or rotate about the locking knob assembly90(in the loosened position) for clamping and securing a workpiece at a desired position.

Referring toFIG.1B, the locking knob assembly90includes a nut90A. The nut90A operably engages with the pivot plate88inside of the cavity88F. The nut90A is configured to threadably engage with a bolt90B of the locking knob assembly90. The head of the bolt90B is configured to operably engage with the upper wall14G′ one of the outer channels14G of the work table14. The bolt90B is also configured to move through the slit88G defined by the pivot plate88. During operation, the bolt90B enables the pivot plate88to rotate about the longitudinal axis of the bolt90B and to pivot on the bolt90B via the slit88G. The bolt90B is also configured to threadably engaged with an adjustment knob90C. The adjustment knob90C is rotatably moveable along the bolt90B (via rotational forces) to enable a woodworker to tighten the pivot plate88to the work table14or to loosen the pivot plate88from the work table14.

The clamping system80also includes at least one button stop92. The at least one button stop92is configured to operably engaged with the work table14. Specifically, the at least one button stop92is configured to operably engaged with the work table14via one of the outer channels14G. The at least one button stop92is also configured to operably engage with an outermost end of a workpiece for securing the workpiece to the work table14. In one instance, the at least one button stop92is configured to operably engage with an outermost end of a rounded or curvilinear-shaped workpiece for securing the workpiece to the work table14(seeFIG.15B).

Referring toFIG.1B, the at least one button stop92includes a bench dog92A. The bench dog92A defines a first or top end92A1, a second or bottom end92A2opposite to the top end92A1, and a circumferential wall92A3that extends between the top end92A1and the bottom end92A2. The bench dog92A defines a V-shaped groove92B that extends into the bench dog92A from the top end92A1towards the bottom end92A2. The V-shaped groove92B is configured to enable the bench dog92A to hold and secure a rounded or curvilinear-shaped workpiece (e.g., a dowel, rod, etc.) when a drill press is drilling a hole into the curvilinear-shaped workpiece. The bench dog92A also defines a through-hole92C that extends from V-shaped groove92B to the bottom end92A2of the bench dog92A. The through-hole92C is sized and configured to receive a connector92D of the at least one button stop92. The connector92D is configured to threadably engage a nut92E of the at least one button stop92to operably engage the bench dog92A with the work table14. Upon assembly, the nut92E operably engages with the upper wall14G′ of at least one outer channel14G and threadably engages with the connector92D to secure the bench dog92A with the work table14(seeFIGS.15A-15B). Such operation of the at least one button stop92is described in more detail below.

Any combination of components or devices of the clamping system80may be used simultaneously when clamping and securing a workpiece to the work table14. For example, at least one pivot clamp (e.g, the at least one pivot clamp87) and at least one button stop (e.g., the at least one button stop92) of a clamping system may be operably engaged with a work table of a machining jig simultaneously for clamping and securing a rounded or curvilinear-shaped workpiece to the machining jig. Additionally, any combination of components or devices of the clamping system80may be simultaneously used with the fence assembly60when clamping and securing a workpiece to the work table14

Having now described the components and devices of the machining jig1, methods of using the machining jig1with the fence assembly60and/or the clamping system80is described in more detail below.

Prior to adjusting the work table14relative to the base table12, a woodworker may operably engage the pair of tables12,14with the riser10in at least one orientation based on the desired drilling angle. As illustrated inFIGS.1A and2, the pair of tables12,14are operably engaged with the riser10in a first orientation where the first ends14A of the pair of tables12,14are facing towards the front end1A of the machining jig1and are vertically above the first foot10E. Once provided in the first orientation, the base table12may be operably engaged with the riser10via connecting mechanisms20. Specifically, each connecting mechanism20operably engage the base table12with the riser10via the attachment apertures10N defined by the platform10G and the first and second inner channels14H1,14H2of the base table12(seeFIG.6).

While not illustrated herein, a woodworker may operably engage the pair of tables12,14with the riser10in any suitable orientation based on the woodworking project. In one instance, a woodworker may operably engage the pair of tables12,14with the riser10in a second orientation where the first ends14A of the pair of tables12,14is facing towards the first side1C of the machining jig1and positioned between the first and second feet10E,10I. In another instance, a woodworker may also operably engage the pair of tables12,14with the riser10in a third orientation where the first ends14A of the pair of tables12,14is facing towards the second end1B of the machining jig1and positioned proximate to the second foot10I. In another instance, a woodworker may also operably engage the pair of tables12,14with the riser10in a fourth orientation where the first ends14A of the pair of tables12,14is facing towards the second side1D of the machining jig1and positioned between the first and second feet10E,10I.

Once assembled, the woodworker may then pivot the work table14to a desired angle relative to the base table12. In order to pivot the work table14away from the base table12, the woodworker disengages the selector34from the protractor plate32(seeFIG.10A) by loosening the adjustable lever mechanism40from the selector34. Specifically, the woodworker applies a rotational force on the threaded handle40A of the adjustable lever mechanism40to loosen the handle40A from the selector34. The rotational force applied on the handle40A of the adjustable lever40is denoted by an arrow labeled “R1” inFIG.10A. Once loosened, the woodworker may apply a linear pulling force on the selector34, via the handle34D, until the selector34disengages from the protector plate32(i.e., the set of selecting teeth34E are disengaged from the set of indexing teeth32E). The linear pulling force applied on the handle34D of the selector34is denoted by an arrow labeled “LM1” inFIG.10A. Prior to or subsequent to the disengagement of the protractor plate32and the selector34, the woodworker loosens the threaded handle40A of the adjustable lever mechanism40from the protractor plate32via a rotational force on said threaded handle40A of said adjustable lever mechanism40. The rotational force applied on the handle40A of the adjustable lever40is denoted by an arrow labeled “R2” inFIG.10A.

Upon disengagement of the protractor plate32and the selector34, the woodworker may then pivot the work table14away from base table12to a desired selected angle “A” (seeFIG.10B) by applying a pivoting force on the work table14. The pivoting force of the work table14away from the base table12is denoted by an arrow labeled “P” inFIG.10B. During movement of the work table14, the pointer36D of the indicator36enables the woodworker to precisely adjust the work table14to the desired angle “A” relative to the base table12. As discussed above, the woodworker may pick any suitable angle in the set of angle indicia32G defined by the protractor plate32at increments of one degree. As illustrated inFIG.10B, the desired angle “A” at which the work table14is positioned relative to the base table12is twenty degrees. While not illustrated herein, the woodworker may also select any angle in the set of angle indicia32G defined by the protractor plate32that is not indexed in the set of angle indicia32G while still being in the range of the set of angle indicia32G (e.g., adjusting the work table14to twenty and one-half degrees relative to the base table12).

Once the desired angle “A” has been selected, the woodworker then secures the work table14at the desired angle “A” by tightening the handle40A of the adjustable lever mechanism40with the protractor plate32. Specifically, the woodworker applies a rotational force on the handle40A of the adjustable lever mechanism40to secure the work table14and the protractor plate32with one another via the adjustable lever mechanism40. The rotational force on the handle40A of the adjustable to secure work table14and the protractor plate32with one another is denoted by an arrow labeled “R3” inFIG.10C.

Prior to or subsequent to securing the work table14and the protractor plate32with one another, the woodworker may mesh the set of selecting teeth34E of the selector34with the set of indexing teeth32E of the protractor plate32. Specifically, the woodworker applies a linear pushing force against the selector34, via the handle34D, until the set of selecting teeth34E of the selector34meshes with the set of indexing teeth32E of the protractor plate32. The linear pushing force applied on the handle34D of the selector34is denoted by an arrow labeled “LM2” inFIG.10C. Once the first and second sets of teeth32E,34E are meshed, the woodworker then tightens the handle40A of the adjustable lever mechanism40against the selector34by applying a rotational force on said handle40A. By tightening the handle40A against the selector34, the selector34is secured to base table12via the adjustable level mechanism40. The rotational force applied on the handle40A of the adjustable lever mechanism40to secure the selector34with the base table12is denoted by an arrow labeled “R4” inFIG.10C.

While the tables12,14were adjusted after being operably engaged with the riser10, any suitable method and/or techniques may be used by a woodworker for orienting and adjusting a machining jig1for a woodworking project. While not illustrated herein, the woodworker may adjust the work table14at a desired angle prior to operably engaging the tables12,14with the riser10.

While not illustrated herein, the woodworker may also use the locking plate assembly46to provide additional support and securement to secure the work table14at the desired angle “A” relative to the base table12. While not illustrated herein, the woodworker may omit the use of the adjustment assembly30and solely relay on the locking plate assembly46to secure the work table14at the desired angle “A” relative to the base table12. Such use of only the locking plate assembly46may be viable when a desired angle is not indexable by the adjustment assembly30(e.g., adjusting a work table to about twenty and one-half degrees relative to a base plate).

As illustrated inFIGS.11-14, the woodworker may desire to use the fence assembly60along with certain components and devices of the clamping system80for a woodworking project. Prior to introducing a workpiece to the machining jig1, the woodworker may operably engage the fence62of the fence assembly60with the work table14via one or both of the first and second outer channels14G1,14G2, which is described in more detail below. Prior to introducing a workpiece to the machining jig1, the woodworker may also operably engage certain components of the clamping system80with the work table14via one of both of the first and second outer channels14G1,14G2, which is also described in more detail below.

As illustrated inFIG.11, the fence62of the fence assembly60operably engages with the first outer channel14G1of the work table14via the adjustable lever mechanisms68. During assembly, the nuts68C of the adjustable lever mechanisms68are inserted into the first outer channel14G1at one of the first end14A and second end14B of the work table14. Once inside, the woodworker may then tighten each threaded handle68A of the adjustable lever mechanisms68with the associated nut68C to secure the fence62with the work table14. As such, the threaded handle68A and the bushing68B of each adjustable lever mechanism68engage with the fence62, and the nut68C of each adjustable lever mechanism engages with the upper wall14G′ inside of the first outer channel14G1. Additionally, the woodworker may operably engage at least one flip stop64with the fence62via the connector64D. As illustrated inFIG.11, a single flip stop64is operably engaged with the fence62. In other exemplary embodiments, any suitable number of flip stops of a fence assembly may be operably engaged with a fence of the fence assembly.

Once the fence assembly60is engaged with the work table14, the woodworker may introduce a workpiece “WP” to the machining jig1. As illustrated inFIG.12A, a first outermost end “OE1” of the workpiece “WP” directly abuts the first rail62F of the fence62. Still referring toFIG.12A, a second outermost end “OE2” of the workpiece “WP” directly abuts the stop arm64C of the flip stop64where the second outermost end “OE2” is orthogonal to the first outermost end “OE1”.

Once the workpiece “WP” is held by the fence assembly60, the woodworker may operably engage the fixed wedge82with the work table14via the fly nut mechanisms84. As illustrated inFIG.12B, the fixed wedge82is operably engaged with the work table14via the second outer channel14G2where the fixed wedge82opposes the fence62on the work table14. Specifically, the head of the bolt84B of each fly nut mechanism84operably engages with the upper wall14G′ inside of the second outer channel14G2of the work table14when the fly nut84A secures with the bolt84B. Additionally, the fly nut84A of each fly nut mechanism84is tightened against the fixed wedge82at an attachment opening of one of the first and second sets of attachment openings82D,82E. As illustrated inFIG.12B, a first fly nut mechanism84is provided with the fixed wedge82at an attachment opening of the first set of attachment openings82D for operably engaging the fixed wedge82with the work table14. Additionally, a second fly nut mechanism84is provided with the fixed wedge82at an attachment opening of the second set of attachment openings82E for operably engaging the fixed wedge82with the work table14.

Once the fixed wedge82is operably engaged with the work table14, the woodworker may then introduce the moveable wedge86. As illustrated inFIG.12B, the moveable wedge86is positioned between fixed wedge82and the workpiece “WP”. Once positioned, the tapered wall86C of the moveable wedge86operably engages with the tapered wall82C of the fixed wedge82, and the planer wall86D of the moveable wedge86operably engages with a third outermost end “OE3” of the workpiece “WP”. In order to secure the workpiece “WP” with the fence assembly60and the fixed and moveable wedges82,86of the clamping system80, the woodworker applies a pushing linear force on the moveable wedge86towards the first ends14A of the tables12,14. The pushing linear force asserted on the moveable wedge86by the woodworker may be applied by hand or by use of another woodworking tool operated by the woodworker (i.e., a mallet, a hammer, or other tools of the like). The pushing linear force asserted on the moveable wedge86by the woodworker is denoted by an arrow labeled “PF” inFIG.12B. The woodworker may continue this force on the moveable wedge86until the tapered walls82C,86C prevent movement of the moveable wedge86or the workpiece “WP” is adequately secured and fixed between the moveable wedge86and the fence62.

As illustrated inFIG.12C, the workpiece “WP” is secured at the desired angle “A” via the displacement of the work table14relative to the base table12. As such, a drill bit “DB” of a drill press is enabled to drill and/or bore a hole into the workpiece “WP” at a drilling angle “B” where the drilling angle “B” is congruent with the desired angle “A”. Once the drilling operation is complete for the woodworking project, the woodworker may simply remove the moveable wedge86from the machining jig1to release the workpiece “WP” from the machining jig1. This process may be repeated for various types of workpiece that may be wedged and/or secured between the fence assembly60and the clamping system80as illustrated inFIGS.12A-12B.

As illustrated inFIGS.13A-13B, the woodworker may also operably engage the fence62of the fencing assembly60at a desired angle relative to the work table14via the angle scale18. During a woodworking project, the woodworker may desire a compound drilling angle where the work table14is adjusted at a first angle relative to the base table12(i.e., selected angle “A” as shown inFIG.10B), and the fence62is adjusted at a second angle “C” (FIG.13A) relative to the work table14. Second angle “C” may be different to the first angle, i.e., selected angle “A”.

As illustrated inFIG.13A, the woodworker may operably engage the fence62with the work table14via both the first outer channel14G1and the second outer channel14G2. The woodworker may first operably engage a portion of the fence62with the first outer channel14G1of the work table14via one of the adjustable lever mechanism68. The woodworker may then operably engage another portion of the fence62with the second outer channel14G2of the work table14via another adjustable lever mechanism68. Once the adjustable lever mechanisms68operably engage with the work table14, the fence62may move and/or slide along the first and second outer channels14G1,14G2between the first and second ends14A,14B of the work table14. Such linear movement applied on the fence62, via the woodworker, is denoted by double arrows labeled “LM3” as shown inFIG.13A. As shown, the woodworker positions the fence62at an angle “C” relative to the first end14A of the work table14by rotating the second end62B towards the second end14B of the work table14while maintaining the first end62A proximate to the first end14A. The woodworker may cease movement and/or rotation of the fence62once the woodworker has determined the angle “C” for the fence62via assistance from the angle scale18. As illustrated inFIG.13A, the angle “C” of the fence62is about twenty degrees relative to the zero-degree marker of the angle scale18and/or the first end14A of the work table14. The fence62is then secured to the work table14via tightening of the adjustable lever mechanisms68against the fence62.

Additionally, the flip stop64is longitudinally moveable along the first and second rails62F,62G of the fence62. The longitudinal movement of the flip stop64is denoted by double arrows labeled “LM4” as shown inFIG.13A. Once a suitable positioned has been determined, the flip stop64may be secured to the first and second rails62F,62G by tightening the connecting mechanism66against the first and second rails62F,62G. Once secured, the woodworker may then introduce a workpiece “WP” where a first outermost end “OE1” directly abuts with the first rail62F and a second outermost end “OE2” directly abuts the stop arm64C of the flip stop64; the second outermost end “OE2” is orthogonal to the first outermost end “OE1” (seeFIG.13B).

Prior to or subsequent to the engagement of the fence assembly60with the work table14, at least one pivot clamp87of the clamping system88is operably engaged with the work table14for clamping and securing the workpiece “WP” with the machining jig1. The at least one pivot clamp87may be operably engaged with the work table14via one of the first outer channel14G1and the second outer channel14G2. As illustrated inFIG.13B, the at least one pivot clamp87operably engages with the work table14inside of the second outer channel14G2via the locking knob assembly90. Specifically, the head of the bolt90B operably engages with the upper wall14G′ of the second outer channel14G2for securing the at least one pivot clamp87with the work table14. Once engaged, the at least one pivot clamp87may be longitudinally moveable along the second outer channel14G2when the adjustment knob90C is loosened from the at least one pivot clamp87to enable the woodworker to position the at least one pivot clamp87along a surface of the workpiece “WP”. Additionally, the at least one pivot clamp87may swivel and/or rotate about the bolt90B when the adjustment knob90C is loosened from the at least one pivot clamp87to enable the woodworker to position the at least one pivot clamp87along a surface of a workpiece.

As illustrated inFIG.13B, the at least one pivot clamp87operably engages with a top surface “TS” of the workpiece “WP” to enable a downwardly force on the workpiece “WP” in combination with fence62and the flip stop64for maintaining the position of the workpiece “WP” on the work table14. The downward force is applied by the at least one pivot clamp87when the woodworker tightens the adjustment knob90C against the at least one pivot clamp87. As illustrated herein, the first end88A of the at least one pivot clamp87operably engages with the top surface “TS”, and the second end88B of the at least one pivot clamp87operably engages with the outer surface14E of the work table14. Once secured, the woodworker may introduce a drill bit of a drill press or similar drilling tool to drill and/or bore a hole at a compound angle enabled by the machining jig1.

As illustrated inFIG.13B, a single pivot clamp87of the clamping system88operably engages the top surface “TS” of the workpiece “WP” to secure the workpiece “WP” to the machining jig1. In other exemplary embodiments any suitable number of pivot clamps of a clamping system may be operably engaged with a surface of a workpiece for securing said workpiece to a machining jig. In another exemplary embodiment, a woodworker may omit the use of a fence assembly and use more than one pivot clamp of a clamping system for securing said workpiece to a machining jig.

As illustrated herein, the fence62of the fence assembly60may be oriented in any suitable orientation on the work table14based on various considerations, including the size, shape, and configuration of the workpiece, the angle of drilling or boring a hole into a workpiece, and other various considerations of the like that arise during woodworking projects. InFIGS.12A-12B, the fence62of the fence assembly60is oriented at a first orientation with the work table14where the fence62is parallel with the first and second outer channels14G1,14G2of the work table14. InFIGS.13A-13B, the fence62of the fence assembly60is oriented at a second orientation with the work table14where the fence62is provided at angle relative to the work table14, and the first rail62F faces towards the second end14B of the work table14. InFIG.14, the fence62of the fence assembly60is orientated at a third orientation with the work table14where the fence62is provided at angle relative to the work table14and, the first rail62F faces towards the first end14A of the work table14.

During woodworking projects, the combination of the fence62and the adjustable lever mechanisms68also enables a woodworker to move one end of the fence62from one of the first and second outer channels14G1,14G2of the work table14to the other first and second outer channels14G1,14G2the work table14while the fence62is still operably engaged with the work table14. For example, the combination of the fence62and the adjustable lever mechanisms68enables a woodworker to move the first end62A of the fence62from the first outer channel14G1and into the second outer channel14G2while the second end62B of the fence62is still operably engaged with the work table14(e.g., moving the fence from the first orientation (seen inFIG.12A) to the second orientation or a third orientation (seen inFIGS.13A-13B and14).

FIGS.15A-15Billustrate the use of at least one button stop92and at least one pivot clamp87of the clamping system for securing a round or curvilinear-shaped workpiece “RWP” with the machining jig1. As illustrated herein, first and second button stops92and first and second pivot clamps88are used to secure the round workpiece “RWP” with the machining jig1. In other exemplary embodiments, any suitable number of button stops and pivot clamps may be used for securing a round or curvilinear-shaped workpiece with a machining jig.

As illustrated inFIG.15A, the woodworker operably engages the first and second button stops92with the first and second outer channels14G1,14G2of the work table14. Specifically, the bench dog92A of the first button stop92operably engages with the first outer channel14G1of the work table14where the connector92D threadably engages with the nut92E inside of the first outer channel14G1to secure the bench dog92A with the work table14. Similarly, the bench dog92A of the second button stop92operably engages with the second outer channel14G2of the work table14where the connector92D threadably engages with the nut92E inside of the second outer channel14G2to secure the bench dog92A with the work table14. Once engaged, the bench dogs92A of the first and second button stops92are longitudinally moveable along the first and second outer channels14G1,14G2when the connectors92D are loosened from the bench dogs92A to enable movement. Such longitudinal movement of the button stops92are denoted by double arrows labeled “LM5” shown inFIG.15A. The bench dogs92A of the first and second button stops92may then be secured to the work table14at desired locations determined by the woodworker when the connectors92D are tightened to the bench dogs92A to prevent any longitudinal movement.

Prior to or subsequent to the button stops92being operably engaged with the work table14, the woodworker operably engages the first and second pivot clamps88with the work table14via the first and second outer channels14G1,14G2. Specifically, the first pivot clamp87operably engages with the first outer channel14G1of the work table14where the bolt90B threadably engages with the nut90A exterior to the first outer channel14G1to secure the first pivot clamp87with the work table14. Similarly, the second pivot clamp87operably engages with the second outer channel14G2of the work table14where the bolt90B threadably engages with the nut90A exterior to the second outer channel14G2to secure the second pivot clamp87with the work table14. Once engaged, the first and second pivot clamps88are longitudinally moveable along the first and second outer channels14G1,14G2when the adjustment knobs90C are loosened from the pivot clamps88to enable movement. The first and second pivot clamps88may then be secured to the work table14at desired locations determined by the woodworker when the adjustment knobs90C are tightened to the pivot clamps88to prevent any longitudinal movement.

Prior to securing the pivot clamps88with the work table14, the woodworker introduces the round workpiece “RWP” to the pivot clamps88and the button stops92. As illustrated inFIG.15B, the first ends88A of the pivot clamps88initially engage with a top surface “TS” of the round workpiece “RWP” as the woodworker moves the round workpiece “RWP” along the work table14of the machining jig1. The woodworker ceases movement of the round workpiece “RWP” once a circumferential wall “CW” of the round workpiece “RWP” operably engages with the bench dogs92A of the first and second button stops92. The woodworker then tightens the adjustment knobs90C against the pivot clamps88by screwing the adjustment knobs90C along the bolts90B. Once secured by the first and second pivot clamps88and the first and second button stops92, the round workpiece “RWP” is maintained on the machining jig1and the woodworker may begin drilling holes into the round workpiece “RWP”.

Referring toFIG.14C, first and second pivot clamps88of the clamping system88may be used to hold and secure cylindrical workpiece “CWP” (e.g., a dowel or rod) on the work table14inside of the V-shaped groove14M. Such engagement of the first and second pivot clamps88with the work table14via locking knob assemblies90in this illustration is identical to the engagement of the pivot clamps88with the work table14as described above. Once engaged, the first pivot clamp87may operably engage a first end “CWP1” of the cylindrical workpiece “CWP” to hold the cylindrical workpiece “CWP” on the work table14inside of the V-shaped groove14M. Similarly, the second pivot clamp87may operably engage a second end “CWP2” of the cylindrical workpiece “CWP” opposite to the first end “CWP1” to hold the cylindrical workpiece “CWP” on the work table14inside of the V-shaped groove14M. In this configuration, the sacrificial insert26is removed from the work table14to allow the cylindrical workpiece “CWP” to rest inside of the V-shaped groove14M; such removal of the sacrificial insert26is described above and illustrated inFIG.14A.

Referring toFIGS.17A and17B, first and second button stops92of the clamping system may be used to hold and secure the cylindrical workpiece “CWP” (e.g., a dowel or rod) with the work table14inside of the V-shaped grooves92B.

As illustrated herein, adjustable lever mechanism94B operably engages the centering device94with the work table14via the first outer channel14G1of the work table14.

During operation, the centering device94may be pivotable on the work table14by rotating the centering device94about an axis of rotation94C defined by a bolt of the connecting mechanism94A. When the adjustable lever mechanism94B is loosened from the centering device, the centering device is enabled to pivot and/or rotate on the work table14by rotating about the axis of rotation94C. The rotation movement of the centering device94on the work table14is denoted by double arrows labeled “RM” inFIG.18. As such, the woodworker may pivotable adjust and/or move the centering device94for a woodworking project by utilizing the angle scale18provided on the work table14. As illustrated herein, the centering device94is provided at thirty degrees relative to the work table14via the angle scale18. When the adjustable lever mechanism94B is tightened to the centering device94, the centering device94is maintained at the desired angle and/or position on the work table14.

As provided herein, any components and/or devices described and illustrated herein may be used separately and/or in conjunction depending on the woodworking project. In one example, any component or device of the fence assembly60described and illustrated herein may be used separately and/or in a conjunction with any component or device of the clamping system80described and illustrated herein with any woodworking project. In another example, any component or device of the clamping system80described and illustrated herein may be used separately and/or in a conjunction with any component or device of the fence assembly60described and illustrated herein with any woodworking project.

FIG.19illustrates a method100of drilling at least one angled hole in a workpiece. An initial step102of the method100comprises adjusting a work table of a machining jig, via an adjusting assembly, to a desired angle relative to a base table of the machining jig. Another step104comprises maintaining the work table at the desired angle via the adjusting assembly. Another step106comprises engaging the base table and the work table to a riser of the machining jig. Another step108comprises engaging the riser to a drill press. Another step108comprises drilling the at least one angle hole in the workpiece.

In an exemplary embodiment, method100may include additional steps of drilling at least one angled hole in a workpiece. The step of engaging the base table on the drill press table includes optional steps of engaging the base table with a riser of the machining jig; and engaging the riser with the drill press table. Optional steps may further comprise of selecting the selected angle via an indicator of the adjusting assembly; meshing a set of indexing teeth of a protractor plate of the adjusting assembly with a set of selecting teeth of a selector of the adjusting assembly at the selected angle; engaging a first securement mechanism to lock the protractor plate to one of the work table and the base table; and engaging a second securement mechanism to lock the selector to the other of the work table and base table. An optional step may further comprise of engaging a fence of a fence assembly with the work table. Optional steps may further comprise of engaging a fixed wedge of a clamping system with the work table; placing a first outermost end of the workpiece against the fence of the fence assembly; jamming a moveable wedge of the clamping system between the fixed wedge and a second outermost end of the workpiece; and securing the workpiece between the moveable wedge and the fence. Optional steps may further comprise of engaging at least one pivot clamp of a clamp assembly with the work table; and clamping the workpiece to the work table via the at least one pivot clamp. Optional steps may further comprise of engaging a first button stop of a clamp assembly with the work table; engaging a second button stop of the clamp assembly with the work table a distance away from the first button stop; abutting a circumferential wall of the workpiece with the first button stop and the second button stop; and preventing movement of the workpiece on the work table with the first button stop and the second button step.

As used herein in the specification and in the claims, the term “effecting” or a phrase or claim element beginning with the term “effecting” should be understood to mean to cause something to happen or to bring something about. For example, effecting an event to occur may be caused by actions of a first party even though a second party actually performed the event or had the event occur to the second party. Stated otherwise, effecting refers to one party giving another party the tools, objects, or e-sources to cause an event to occur. Thus, in this example a claim element of “effecting an event to occur” would mean that a first party is giving a second party the tools or resources needed for the second party to perform the event, however the affirmative single action is the responsibility of the first party to provide the tools or resources to cause said event to occur.
