Edit: This jig was featured in a Fine Woodworking Magazine article. May/June issue #226.
Note: The bottom clamps were redesigned on the jig in the article.

Figured Maple and Bubinga dado jig

I looked at a lot of dado jigs before designing this one. They all seemed to use c-clamps to hold to the work.
I wanted the clamp contained on the jig, so here’s what I came up with. Notice in picture on #5, the adjustble clamps on the bottom of the jig. the front edge has a spring embedded to spread pieces so they won’t bind when moving the jig. Using T-track underneath, the outfeed side slides to fit any width up to 24” wide. The wooden clamps lock down on T-bolts. The width of the dado is adjustable also. The left side is stationary, while the right side slides back and forth for the dado width. The small clamp at the outfeed end locks the width at that end, with a knob. It is set up to use a template guide on the router. So far I have used a 1/2” sraight bit, but you could use any size bit. With a 1/2” bit, you get a 3/4” dado with two passes. I plan on doing a blog to make all this more clear in case I have totally confused everyone. Thanks

A fantastic jib. And not too shabby also.

Great looking jig with lots of forethought. Jigs that do one thing sometimes can be limited, but it looks like you really have a lot of options with this one.

I could have used that exact system about 6 hours ago. I’ll have to make one in a similar style and fashion :D

Beautiful work but I don’t see how you make adjustments for the width of the dado. from pictures it looks like there’s no adjustment?
