Abstract

An infinity jig, infinity plug and a method of forming an infinity joint is presented. The infinity jig has a base with a work surface and an upright with a work surface connected to the base at an approximate perpendicular alignment. The upright includes a plurality of drill guides that are positioned such that a portion of a drill bit inserted into the drill guide extends below the work surface of the base. An infinity hole is formed by using a drill bit having a stop collar to drill partially into a workpiece with a portion of the drill bit exiting a connecting surface of the work piece. To form an infinity joint, two workpieces having infinity holes therein are aligned with one another and an infinity plug is inserted in the aligned infinity holes. The infinity plug pulls the two workpieces together providing a tight and aesthetically pleasing joint.

First claim

What is claimed is:

1. A drilling jig comprising:
a base;
the base having a planar work surface;
an upright;
the upright connected to the base;
the upright having a planar work surface;
wherein the planar work surface of the base is positioned in a generally perpendicular orientation to the planar work surface of the upright;
a first drill guide having a center axis extending through the planar work surface of the upright in a generally perpendicular orientation;
wherein the first drill guide is configured to receive a drill bit therein;
wherein the first drill guide is configured to allow the drill bit to rotate within the first drill guide;
wherein the first drill guide is configured to allow the drill bit to move laterally through the first drill guide as the drill bit rotates so as to facilitate drilling a hole into a workpiece;
wherein the first drill guide is aligned to extend in a generally parallel orientation to the planar work surface of the base;
wherein the first drill guide is positioned such that an exit portion of the first drill guide is below the planar work surface of the base;
wherein the exit portion of the first drill guide intersects the planar work surface the base;
wherein the exit portion of the first drill guide is less than half of the circumference of the first drill guide.

2. The drilling jig of claim 1 wherein the exit portion of the first drill guide corresponds to less than half of the circumference of the drill bit.

3. The drilling jig of claim 1 wherein the first drill guide includes a hardened metallic portion for increased durability and wear resistance.

4. The drilling jig of claim 1 wherein the upright is removably connected to the base.

5. The drilling jig of claim 1 wherein the first drill guide includes a dust collection opening for removal of dust and debris.

6. The drilling jig of claim 1 wherein the first drill guide includes a drill bit cut out area positioned in line or below the planar work surface of the base.

7. The drilling jig of claim 1 wherein the first drill guide includes a drill bit cut out area positioned in line or below the planar work surface of the base that is formed of a hardened metallic material for improved wear resistance.

8. The drilling jig of claim 1 wherein the first drill guide includes a drill bit cut out having a dust collection opening.

9. The drilling jig of claim 1 further comprising at least one adjustable stop for positioning a workpiece.

10. The drilling jig of claim 1 further comprising a plurality of holes that receive an engagement peg for selectively positioning a workpiece.

11. The drilling jig of claim 1 further comprising a vacuum snout connected to the drilling jig for removal of dust and debris during use.

12. The drilling jig of claim 1 further comprising a second drill guide positioned in the upright.

13. A method of forming a joint for joining two workpieces, the method comprising the steps of:
providing a drilling jig having:
a base having a planar work surface;
an upright having a planar work surface;
a drill guide having a bore extending through the upright; and
wherein the bore of the drill guide is aligned to extend parallel to the planar work surface of the base and is positioned such that a portion of the bore of the drill guide is below the planar work surface of the base;

providing a workpiece having a face and a connecting surface, wherein the face and the connecting surface extend in a generally perpendicular orientation to one another;
placing the face of the workpiece onto the planar work surface of the upright;
aligning a cylindrical drill bit having a circumference with the bore of the drill guide;
inserting the drill bit into the bore of the drill guide;
rotating the drill bit within the drill guide;
moving the drill bit laterally along the bore of the drill guide as the drill bit rotates;
drilling a hole into the face of the workpiece wherein a portion of the drill bit exits the connecting surface of the workpiece;
wherein the portion of the drill bit that exits the connecting surface of the workpiece is less than half of the circumference of the drill bit.

14. The method of claim 13 , further comprising wherein the face of the workpiece is placed flush against the planar work surface of the upright during the drilling step while the connecting surface of the first work piece is placed flush against the planar work surface of the base during the drilling step.

15. A drilling jig system comprising:
a first planar work surface;
a second planar work surface;
wherein the plane of the first planar work surface is positioned in approximate perpendicular alignment to the plane of the second planar work surface;
the first planar work surface configured to engage a planar face of a workpiece;
the second planar work surface configured to engage a planer connecting surface of the workpiece;
a first drill guide having a bore and a center axis;
wherein the center axis of the first drill guide extends in an approximate perpendicular orientation through the first planar work surface;
wherein the center axis of the first drill guide extends in an approximate parallel orientation with the second planar work surface;
wherein an exit portion of the bore of the first drill guide intersects the second planar work surface;
wherein the exit portion of the bore of the first drill guide is less than half of the circumference of the first drill guide;
wherein when the face of the workpiece is aligned on the first planar work surface and the connecting surface of the workpiece is aligned on the second planar work surface the first drill guide is aligned such that more half of the bore of the first drill guide overlaps with face of the workpiece and the exit portion of the bore of the first drill guide extends past the connecting surface of the workpiece;
wherein the first drill guide is configured to receive a drill bit therein;
wherein the first drill guide is configured to allow the drill bit to rotate within the first drill guide;
wherein the first drill guide is configured to allow the drill bit to move laterally along the center axis of the drill guide as the drill bit rotates so as to facilitate drilling a hole into the workpiece;
wherein when the drill bit extends through the first drill guide and into the workpiece a hole is formed within the workpiece wherein more than half of the drill bit is received within the face of the workpiece and less than half of the drill bit exits the connecting surface of the workpiece.

16. The system of claim 15 , further comprising:
a second drill guide having a cylindrical bore and a center axis;
wherein the center axis of the second drill guide extends in an approximate perpendicular orientation through the first planar work surface;
wherein the center of the second drill guide extends in an approximate parallel orientation with the second planar work surface;
wherein an exit portion of the second drill guide intersects the second planar work surface.

17. The system of claim 15 , wherein the first drill guide is cylindrical in shape.
