Matching spacer blocks make it easy to locate the shelf-pin holes in the template. Align the template to bore the center hole and clamp a stop against its end. Bore the hole, then put a spacer between the template end and the stop. Drill again, insert another spacer and repeat.

Glue the three fences to the ends and front edge of the template (left). To use the drilling template jig, set it on a cabinet side, fences tight against the edges, and clamp it securely. With a #6 self-centering bit, drill pilots for the hinge plates. Switch to a 1/4" self-centering bit and drill the shelf-pin holes (below). Flop and reclamp the template to drill the back shelf-pin holes.

The hinges must be located precisely 37mm back from the cabinet's front edge — that translates to l²⁹/^'. The shelf-pin holes don't have to be placed on the same line, but doing so makes layout a bit easier. You have to account for the 1/2" taken up by the fence. Set a marking gauge to 1^sVm" and scribe a line on the template. Across this line, mark the mid-point and the centers of the hinge plates. (Because die upper and lower plates are positioned differently, label the top end of the template.)

Drill the hinge plate pilot holes and countersink them on both sides of the template.

Now, bore the shelf-pin holes in the template. If you'll use a self-centering bit for boring shelf-pin holes, it has a 3/8"-diameter collar, so make the template holes 3/8" diameter. Here's an easy way to drill equally spaced shelf-pin registration holes in the jig: Cut a half-dozen l¹ V'-long spacers. Set a fence on the drill press to center the bit on the scribed line, and clamp a long auxiliary top to the table. Line up the template's midpoint directly under the bit, and set and clamp a stop against the template's end. Drill the first hole. Place a spacer between the template and the block. Drill another hole. Add a second spacer and drill again. Repeat until you've drilled seven holes.

To extend the line of holes in the other direction, slide the template back to the mid-point, switch the reference block to the other side of the setup, and step off the holes.

Glue the three fences to the template, and you are ready to start drilling those cabinet sides. J&

Using the Jig

Building the Jig

Drill hinge pilots in the template using a hinge plate as a pattern (left). Align the plate, then drill with a self-centering bit. Countersink both sides of the template holes (above).
