I have tried the free hand methods, but they just don't work for me. So I found a machine shop to make me a set of lead screws with 8, 10 & 12 TPI and custom fit nuts with zero back lash. I then mounted the nut on my cross feed unit and I am set... My cutter is a double bevel 60° that fits in my head stock and I run it fast (2000) RPMs. This assembly cuts the best threads in wood that I have ever seen. Plus, set up is a snap. If anyone is interested in this idea, I can send you a few Pics of the assembly. My e-mail is sydsellers@gmail.com.
Happy threading..
