Dado Jig for Trim Router

MY take on the exact-width Dado Jig I first saw at the Wood Whisperer (video here). I simplified it a little bit. As I mentioned in my review of the Ridgid Trim Router (here) the square base makes a nice “bushing” for the jig. Just set the base along the guide and move along. I use a simple 1/2” straight bit.

One thing I did do is indicate on the jig which direction the router should face, as I think mine may not be 100% centered, so that can cause some problems. The last picture shows a little depth gauge I use to make sure that it is the right depth.

It’s all made of plywood and uses jig parts that can be had at any hardware store (mine came from the local Ace). I used it to make the bottom shelf dado for the Bathroom Vanity I just finished and it produced nice, tight dadoes.

I should mention that it is about 30” long.

I guess I should get busy making one of these, or buying one of the plywood sized bits because I have something I have to make for my wife really soon that will need slightly less than 1/4” dados and I have a 1/8” bit to do it. Thanks for posting this.

Nice project. Very useful. Thanks for sharing. Also thanks for the Ridgid Trim router review. I have been considering either that model or the Bosche Colt.

One thing about the Colt is that it does not come with a clear baseplate. The Ridgid also comes with both a square and a round one and they’re very easy to change out.
