I was lurking around on the Wood Whisperer’s website and ran into his Exact-Width Dado Jig. I liked it a lot, but it failed when Marc had to reach under the jig to tighten his nuts. Please check Marc’s jig out and also his explanation on his video on how to use the thing, he does a way better job than me!!
I had my own cabinet shop for years and I always struggled with setting up the dado blades in the table saw, a little wider for solid woods and a little less for plywood. I was never able to hit it dead on. But I could not handle Marc’s jig with his nuts under the table.
So I came up with the “never fail” dado jig, with the nuts above the table.
And if it was not for the fact that I was building a dresser for my lovely wife’s closet, and it has a bunch of dado’s in it, I would have never build this jig.
This is one of those jigs, once you build it, you can’t live without it.
The boards are made of 3/4 plywood cut to 2 1/4 width. Add a strip of 1/4×3/4 hard wood to the edge, glue not nail.
On the two long boards cut a small rabbet on the hardwood strip 1/8×3/8. This needs to face up when assembling the frame. See picture above.
The jig takes just a hand full of hardware. One side, the side with the screws is also glued and needs to be VERY square!!! Clamp it first for a while before you actually put the screws in place.
When all hardware is in place it is time to true the jig up to ONE set of guide bushing and router bit. This set will be the set that will be married of to this jig. Put a board in the jig, use clamps as shown below.
With the first run you will shave a little off the sides of the jig. Now it is time for the true test. Set again a board in the jig clamp it tight, tighten the nuts, take the clamps off and run the router up one side and back the other side of the jig. I feel like blah-blah-blah, I am not getting it explained. Best is go to the link up above and watch the video Marc did so well.
Anyway, thanks for reading this post and I hope you have as much fun with this jig as I did.
