Dado Wiz Zeros in on Perfect Fit for Dados or Grooves

Our staff has an ongoing discussion about  the best way to make dados. Whether using a dado stack or router, the trick is getting the dado or groove the proper thickness to match the material. I prefer using a router; that’s why I was pleased to learn about the
The Dado Wiz (the black plate shown at right) locks to most clamps and guides ( 5/8″ thickness maximum). Temporary pins are put in place on the Wiz and a sample piece is used to adjust the guide to perfectly fit the shelf or divider material.

The included brass template guide and your 1/4″, 3/8″ or 1/2″ router bit is then used to make two passes (one up, one back) to make a perfectly sized groove or dado with a single setup. The Dado Wiz slides on your guide during the cut, controlling the position of the bit.
The Dado Wiz efficiently answers a need when routing dados. It does come at a price that’s a little steep, but if you prefer routed dados, this jig belongs in your shop.
