Making wood plugs
Save time making wood plugs by using a piece of tape to remove them from their holes. Use a plug cutter on the drill press to bore a row of plugs to the depth you require. Cover the row with a strip of masking tape, then rip the plugs to length on the band saw and simply peel off the tape to remove the row of plugs.
Boring the holes
Set the jig on the drill press table. Mark the location of the first two holes and seat the workpiece against the fence of the jig, aligning the first drilling mark under the bit. Butt a guide block against the back of the jig and clamp it to the table. Bore the first hole, slide the jig along the guide block, and bore a hole through the dowel holder. Fit a dowel through the hole in the holder and into the hole in the workpiece. Slide the jig until the second drilling mark is aligned under the bit. Clamp the jig to the table and bore the second hole. To drill each remaining hole, retract the dowel and slide the workpiece along the jig fence. Push the dowel down into the last hole you made.
