I found a motor that is 3/4 hp and another that is 1.2hp. They come with speed controller. So I don’t think I would need a wiring diagram. But I sure appreciate you offering your help! Do you think 1.2 hp would be too much for a watchmaker’s lathe? -
At the moment I have neither EDTA solution nor Evaporust, so I tried with a citric acid solution. This gave satisfying results for most of the parts, except for the ones that are really heavily corroded. I will see whether I can acquire one EDTA or Evaporust and try that next. -
This guy (Minimachining) has a playlist of him setting up and using various attachments on his Sherline lathe. I know nothing about CNC machines but had a question about making screws. Watchguy.uk has a section on his website where it allows you to enter parameters for screws and wheels and then 'generate code'. Is it as simple as that sounds, can you 'tell' the CNC machine to cut you a screw (or stem) by giving it the code for a particular screw or stem and it happily makes one for you? -
