Hi Fred, Just a quick note.... We have done quite a bit of talking about the ball/radius turners earlier on in the year. There are quite a few re-designs on Steve Bedairs type too, maybe one would adapt to your lathe without the new parts?
If you use the search function on the tabs at the top of the page and type in "ball turner" and hit enter... loads of references come up, you are bound to find something of interest in there!? (most of the posts are in 'tips and tricks' or 'tools')
Hope this helps, Good luck ;D
Ralph.
