I have this Enco mill and a couple questions about it. The quill feed handle will simply pull right off of the shaft. The handle and hub that it rides on are on the shaft and held in position with a keyway and key. The handle is held onto the hub with a C clip that I have removed for the pictures. But I can't for the life of me figure out how they held the hub onto the shaft. I think I need someone with either the same or a similar mill to help me out here. That's just a start, I have a couple other questions about this mill but I start another thread.
