I wanted to drill a pattern of 3/4” holes in my work surface to use for clamps and stops. 4” x 4” seemed like a good pattern size. I’ve seen others use an expensive indexing guide but I didn’t need that kind of precision or want to invest the money.
I decided to use some pegboard as a guide. Once I lined it up, I drilled 1/4” holes through a couple of the 1/4” diameter peg holes. This gave me two points to insert 1/4” dowels as indexing pins so I could repeat the pattern or move the pegboard and extend the pattern.
I marked the selected 4×4 pattern holes and used a self-centering drill bit to drill pilot holes. Then I made a jig to hold the 3/4” bit fairly straight and quickly bored the desired holes.
