The title is a little miss leading. The leadscrew is actually a cylinder with threads on it. It rides on the spindle input side. Right in front of the collet release lever. The chaser is mounted on a arm that comes down and contacts the leadscrew. I just won this auction. It has blank leadscrews so I can make my leadscrew. But I do need the brass chaser.
