The jig is designed for a single blade, in my case a 1/8” Freud rip blade. A pin that matches the kerf rides between spacers that are a 1:1 ratio to the size box joints you want. First time I was anxious and didn’t make the spacers consistent so the joints turned out crappy. Second try I used 1/4” plywood for the spacers and the joints came out perfect, snug but enough room for glue. The kerf is 1/8” and the pin is just about .002 smaller.
