I have found an easy way to modify a wooden lever cam clamp to move a table saw fence or router fence in fractional quantities, using easy-to-find hardware: a 1⁄4“-20 T-nut, 1⁄4“-20 carriage bolt and matching wing nut, washer and hex nut.
You can make your own cam clamps or buy them from a woodworking shop.
Drill a 5⁄16“Hole in one end of the cam clamp for the T-nut and glue the nut in place (I used Weldbond adhesive). Thread the bolt through the nut, then cover it with the hex nut, washer, and nut. fins.
Your micro-controller is ready for action.
I use them to adjust the fences on my table saw and router table. Just lock the jig near the fence and turn the wing nut, making the cart bolt head move the fence. I made both the right and left versions so that I can push the fence to either side of the blade or tip.
With half a rotation of the wing nut I can push the fence 1⁄40“(A full rotation is 1⁄20“).
I have found that with this simple jig I can discover the best settings for my fence. Plus, I can still use the cam clamps for my general tightening needs. –Jim Eckblad
