Was given a very nice looking ballscrew the other day. No markings on it. Measures 5 tpi with a diameter of .450 inches on the money. Looks rolled, but Its the purtiest rolled screw I have seen yet. Its possible its ground. I don't know brand or background. Any guesses on getting a ballnut that will fit it? Its about 15 inches long. Will make a beautiful screw for a lathe conversion me thinks.
Any input would be appreciated. I think its SS hence the pretty factor. BTW its single start.
