This might not be the world’s cheapest template, but it’s got to be pretty nearly the cheapest.
For my Stickley Inspired Entertainment Center I needed to drill about a hundred shelf support holes to hold up the three shelves. I bought a yardstick, cut it to length and had my son drill holes every one inch.
We then used it on the drill press as a template to drill the shelf support holes. It worked out great and we have a nice template for next time we need a bunch of evenly spaced holes.
