Hi, Bill. I have one of those lathes. It's worked reasonably well. I'd sell it, but it would end up costing a lot more than I would get out of it, to buy another lathe. The indexing wheel really doesn't work to well. I need to drill all the holes out a couple/few thousandths. By the way, you need 2 of those 38mm wrenches. Don't know if have one or none!
If you want to turn anything really large, take very light cuts. It's fairly easy to stall that thing.
And you are right, not many parts available for it. I used to change the headstock assembly on them rather frequently years ago. The replacements were the mechanical(reeves) drive, not the electronic speed control. Mine however is still original.
Hope it works well for you
I have found that hand tools are the best choice when I want to make mistakes at a slower rate of speed.
I don't suffer from insanity. I enjoy every minute of it.
