My first jig: Handheld Router Dado Jig

I started on my router table and realized that I really needed a jig to do the Dado cuts with my router. This is a modification from a Jig book. Took me an afternoon to make, I went very slow to make sure that it was square.
It is made of hardboard, MDF and a piece of oak.

I would LOVE to get specs on this. Just finished my third piece of $65 maghony trying to get straight dados or a back rest insert on a kids hope chest. Wish I had this before i ruined the first two.

Nice Jig! I just finished something similar. I’ll get some photos taken so you can see it as well. The jig I made apparently originally appeared in woodsmith magazine. Nice work!

Taunton’s Complete Illustrated Guide to Jigs & Fixtures (Complete Illustrated Guides)
That is the book that I got the design from.
Here are the specs
The 1/4 inhardboard is 4in wide (make as long as you want)
The 1/2 in MDF 2 inches wide (as long as the hardboard)
The crosspieces are 12 inches long, and are made out of 1×3 oak
I added the T-bar from the plan and shortened the length from the plan.

So to customize for your individual router, when the jig is closed all the way you should be able to just fit your router between the 1/2” MDF right? That way you could set the width of the opening to the width of the dado if it was wider than your bit and just run the router against the 1/2” mdf stops.

Hmmmm may have to pop over to the woodsmith shop for some t-track and a couple of knobs…looks like a great jig, thanks for sharing.

I made one of these a couple years ago. I thought it would satisfy all my dado needs. It wasn’t the case, I would get a single groove of slightly varied width often resulting in a sloppy fit. The problem was my router base plate was not over hanging evenly around the base causing the bit to drift in and out following the alignment of the plate. I used the same router you have in the pic. I used the jig a few times and that was all. I have seen a variation of this jig that used a flush-cutting top bearing bit where the router sits atop 2 strips of 3/4” stock.

Good point about accuracy. I did some research and the solution is to make a custom square or rectangular baseplate. The project I am working on now does not require dead on accuracy, but I will be making the new plate soon.

This may help, because the bushing is more accurate. The outside diameter of the base plate is not perfect. just a thought.
