lathe design

I think one of the last of the 'Holbrook 8' Might be well worth a look. Separate drives for threading and auto feed, which share a common micro-adjustable dog clutch activated by saddle position. The bed is massive. In theory you can cut threads at high speed but I have never dared try!

There is a picture on the lathes.co.uk site but if you are near Gloucester you can have a look at mine.

If you don't mind too much, I won't - you usually talk practial sense, and I'm usually much better at the theory than the practice anyway.

I'm a physics geek. Which is several orders of magnitude closer to actual reality than a maths geek. However, I have discovered that physics geeks are several orders of magnitude from engineers, who are themselves often a couple of orders of magnitude from machinists in actually knowing how to shape bits of metal. Forget everything you know. It's fun to try to work it back to first-principles once you know it, but learn from those who do know first.

If you remember you know nothing you'll learn a lot.
