I found this sweet simple little jig entirely by accident but it’s simplicity is also its genius. Use it for shelf dadoes, lattice dadoes, lap joints, fluting… maybe even a miniature version with a brass keel.
This is an excellent jig. I have been building fine furniture for years, and you need to use the tool for which it was designed. I took this out of the box, and cut a circle from hard maple. It took 4 passes, but the top came out beautiful.
