Exact Width Dado Jig
This exact width dado jig is very similar to the one that Marc Spagnola of the Wood Whisper.com built during a recent Guild Build. Marc posted a video on You Tube showing the construction of the jig. This is a similar version of the jig that I’m using as a sample of my plans. The actual plans are even more detailed and usually range from 10 – 20 pages in length.
If you ever use sheet goods for shelves mounted in dados in your case sides you will appreciate the accuracy you can get using this exact width dado jig. This jig is designed to dado boards up to 24” in width. Simply clamp the jig and work-piece to a work surface, set your fixed fence on the line for your dado insert the actual shelf, snug the moveable fence up to your shelf and lock it down. Now using your router with a guide bushing and spiral or straight bit (smaller than your dado) rout along the fixed fence and return on the adjustable fence….. and presto perfect dados.
