I am restoring an antique spinning wheel. Tension adjustment on the drive band is via wooden screws. The pitch is 1 inch x3 or 4 tpi – about half as many threads as on the Bealle –type threading tools. Anybody have a trick with any combination of hand and power tools (lathe, router, etc) for turning such threads, or making the tools to do so. FW 33 and Oct 91 show methods for making twists on rounds, but these articles don’t seem to contemplate using similar methods for cutting wooden screws. Any thoughts appreciated.

Richard Heckman has a PhD in Physics and made a study of wooden
screws and how to make them without using special tools. Here is a web site to see a video of one of his presentations.
