I've got an antique Ames lathe - very well used - and the dovetails are well worn in the middle and unworn at the ends. I've done a little scraping at the most obvious high points which helps. Is there a standard way to proceed from here? Obviously I don't want to change the angles or destroy the parallelism. I could lap the surface, but what sort of tool would hold the angle properly?
Any clues appreciated! The machine is at least 50 years old but when everything (and I mean EVERYTHING) is tightened down very very well, I can turn almost anything with a good result.
