Hi Steve. Great effort. I have 7X12 lathe and mini mill machine. I have tried to hobble worms and it kind of worked. I also have small rotary table so I can do reasonably accurate indexing cuts. But my biggest problem is how to calculate blanks diameter. All what I can find on Web requires mechanical engineering degree to understand. Unfortunately I’m electronics guy and last time I worked on real lathe was about 45 years ago. So how do you calculate diameter? I’m casting my blanks from scrap aluminium.
