For my next project I’m going to make some raised dog dishes, and that requires me to make some decent sized holes to mount the dishes in. I thought I would be able to just run down to my local woodworking store and pick up a jig, but oh no. I must have the worst luck on the planet; every time I think something should be easy, it ends up becoming a big ordeal. But I digress.
The jigs available locally fall into 2 categories: template & arm style. The template style jigs are usually for circles 4″ in diameter or smaller, and the arm style are for circles 7″ to 8″ and larger. I need to make circles that are roughly 6″ in diameter. Thus, instead of ordering a jig and waiting a week for it to be delivered, I made one last night.
I made it from some scrap 1/4″ thick Lexan, I had leftover from my router table build. The only unpleasant task involved in its construction, was having to turn off the drill press after every hole, and clean the melted material out of the bits flutes. As it is now, I can make holes from 4 to 14 inches in diameter in quarter inch intervals.
