In the July/August, 2015 issue of Machinist magazine I saw the plan for a lathe threading devise. I needed some practice for a upcoming major mill project and I could see that this project would fit the bill. This project needed dovetails cut and drilling on bolt circle. I made mine from scrap that I had in shop and the dimensions can be adjusted for your needs. I feel as though this would be a good project for someone just learning the basic skills as it combines mill and lathe work. After finishing the project I found it works as described and does make threading on lathe a lot easier.
