Thread milling on a converted wood lathe. All parts are made of wood. The machine works perfectly. The pitch of the thread can vary from 2tpi to 5tpi, get set with wooden gears.
Minimum 1 inch diameter, maximum diameter 6 inches. maximum length of 4 feet.
The whole project is designed and built by myself.

Outstanding. Great piece of engineering. You have got to make a video of this. Where did you get the plans? This would be great to see in action.

That’s six out of ten votes for a video! You have built an incredible device, I along with many others are contemplating spending a few hundred dollars for bench screws and you built THE MACHINE. Bravo PM me if you are going to do custom work.

7/10 Awesome work. Is there a lead screw that the end gears turn? Inquiring minds want to know.
