This jig is a little different than most router dado jigs. It is made from a 2’ x 2’ plywood square. There are no slots to cut. Instead, the adjustable rail is clamped down with a couple blocks. It accommodates stock from 1/2” to about 2”.

For those who are interested, a build video and a free parts diagram can be found here:

Even though I already have undersized bits for plywood, this is so much nicer since it still tends to vary.

I picked up a 2×2 today at Lowes as well.

Great stuff Jay!

I could have used this a week ago when I built mine. I followed the wood whisperer plans which are also good but not nearly as good as your set up. His jig cant be used directly on top of a bench or work surface, it must be used hanging off the work surface while it appears yours can be used anywhere. I like it! I might have to scrap the other jig and try yours instead.

wow. the speed you move when glue’ing and nailing… redbull? :)
this also will be on my todo list!
and I see you prefer to use the fixed base instead of plunge base. might have to give my fixed base a try (have actually never used it for my bosch 1617)
