Abstract

According to one embodiment, a system for locating a drill press or router table fence comprises a center-post insert having a protrusion located in a central portion of the center-post insert, a center-point template having a plurality of openings sized to closely receive the center-post insert, wherein the openings are located at a range of predetermined distances, and a fence having a securing mechanism, the fence located at a distance set by the center-point template, wherein the center-point template is placed on the center-post insert at a chosen opening, and the fence is secured against the center-point template at a distance determined by the chosen opening.

Claims (29)

1 . A system for locating a drill press or router table fence, comprising:

a center-post insert for installation in an inset recess of a table, the center post insert having a protrusion located in a central portion of said center-post insert;

a center-point template having a plurality of openings sized to closely receive said center-post insert, wherein said openings are located at a range of predetermined distances; and

a fence having a securing mechanism, said fence being positionable at a distance set by said center-point template;

wherein said center-point template is configured to be placed on said center-post insert at a chosen opening, and said fence is secured against said center-point template at a distance determined by said chosen opening.

2 . The system of claim 1 , further comprising the table having the inset recess.

3 . The system of claim 1 , further comprising first and second dowel rod stops for assembly with the table to secure the fence at the set distance.

4 . The system of claim 3 , wherein each of said dowel rod stops has a T-bolt installed at a flat end of said dowel rod stop and a clamping knob installed at an opposite end of said dowel rod stop, said clamping knob used to secure said dowel rod stop to said table.

5 . The system of claim 1 , further comprising a blank insert having an outer perimeter that matches an outer perimeter of the center-post insert.

6 . The system of claim 1 , wherein said securing mechanism comprises a clamping fastener.

7 . The system of claim 1 , wherein said plurality of openings are organized on said center-point template in two sets of opposite angled parallelograms.

8 . The system of claim 1 , wherein the center-point template comprises at least forty openings.

9 . The system of claim 1 , wherein the center-post insert comprises a panel, a cylindrical protrusion, a secondary support piece, and two screws.

10 . The system of claim 1 , wherein the fence includes a T-square guide bar, a first T-slot for stops, and a second T-slot for an extension bar.

11 . The system of claim 10 , wherein the fence accepts a plurality of fasteners along said first T-slot to secure stops at different distances where a workpiece can be secured against.

12 . The system of claim 11 wherein the stop assembly has a set screw to lock against the bottom of the T-slot.

13 . The system of claim 12 wherein the thumb nut can be loosened to remove the stop without dislodging the set screw.

14 . A method for operating a system for locating a drill press or router table fence, comprising:

placing a center-post insert into an inset recess on a workshop table;

placing a center-point template on top of said center-post insert using one of a plurality of openings sized to closely receive said center-post insert;

positioning a fence along an edge of said center-point template at a position determined by the selected opening;

securing said fence against said center-point template using a securing mechanism;

removing said center-point template from said center post insert;

removing said center-post insert from said inset recess;

placing a blank insert into said inset recess; and

positioning a workpiece against said fence.

15 . The method of claim 14 , further comprising providing two dowel rod stops assembled with the workshop table, said dowel rod stops being operable to slide along said workshop table and secure flush against said fence, allowing said fence to be removed and reset after said blank insert is placed into said inset recess.

16 . The method of claim 14 , wherein said fence includes a T-square guide bar, a first T-slot for stops, and a second T-slot for an extension bar.

17 . The method of claim 14 , further comprising providing a single dowel rod stop on said workshop table, said stop able to slide along said workshop table and secure flush against said fence, allowing said fence to be removed and reset after said blank insert is placed into said recess.
