It is used on a capstan unit, or lathe, for turning features on the end of the work; basically a roller box, without the rollers. What is the diameter of the mounting shank?
it came with a Seneca Falls star lathe that i am getting rid of but it has c Taylor stamped on it so it must be off one of their capstan lathes so not much use to me so it's off to eBay for auction as i do not have a clue what it is worth. thanks for all your help.
