Hi all!

Any advice on where to find thread cutters for wooden screws that have a course thread per inch? I bought a cutter for 1 1/2” dowels for use on my son’s first bench (wagon wheel vise), it turned out great but the threads are way too fine. It takes a lot of turning to move the jaw. To keep things simple I didn’t try to incorporate any quick release mechanism… Maybe a mistake in hindsight.

I’d like to use a wooden screw for a leg vise on my bench. I know you can buy pre-made screws from a number of places but would like to do it myself if I can.

The Beall Wood threader makes wooden threads on the screw and includes a tap for making the female threads. For the 1.25 and 1.5” size it is 5 threads per inch. Don’t know if that is too fine for what you want.

If you build your own threading jig, you can buy carbide 60 degree V cutters. Might hold up better, and definitely be quicker that reworking an old file into a cutter. You could probably use the cutter for your current thread cutter as well. I wish there was a Beall type threader for two, two and a half, and three inch screws that could be purchased.
