Hi Les,
Can you explain more what you're after in the way of 'tooling and accessories' – that's a very broad question?
I'm not aware of anything made specifically for the ML4 in the way of spare parts or replacement Myford accessories. But it's a typical small lathe that will work with modern tooling provided it physically fits. (Small HSS or Indexed tools just have to be shimmed to centre height; bigger ones will be too high.) Fitting new chucks is more complicated.
I wouldn't worry about the quality of Far Eastern tools relative to the ML4 unless there's a specific reason.
What are you trying to do with the lathe?
Dave
