Router Dado Jig

With this shop-made jig, you'll be routing dadoes and grooves that fit perfectly. Plus, it features a handy, built-in clamp that makes setup a snap.

Sets up in seconds... No honestly, this isn’t some catalog hype, you can really start routing with this jig in seconds. All you have to do is clamp the jig in place and set the dado width — that’s it. There are a few features to this jig that make it so easy to use. The best is the self-clamping mechanism that allows the jig to clamp directly to the workpiece without having to use a bunch of other clamps. With just one step, you can secure the jig to your workpiece and automatically square it to the edge as well. Another plus to this jig is that you can align it right on the dado layout lines.

There’s no messing around with router base offsets here. The reason is that the jig is customfit to your router and bit when you build it. This lets you quickly set the jig in place and always know where the dado is going to be. There’s just one final feature that I want to mention about this jig. It’s fully adjustable for any size dado from 1/2" to 1 1/2" wide. This means that you won’t have to guess at trial-and-error settings to custom-fit a dado to undersized plywood. All you need is the piece that will fit in the dado (or a cutoff) to set up for gap-free dadoes every time.
