The post that Sir John made last December about his Swing Up Treading Tool stuck in my mind. So when it became time to thread the neck of the ER collet chuck I built this week, I made a temporary version of it. Along with the ability to instant reverse my little lathe, and it's variable speed capability (the Treadmill motor) the tool worked great.
So yesterday I rebuilt the tool and thought I would share some photos of it with you.
I used a threading tool bit holder that I've had for some time. Cut it off and drilled a hole for the guide pin and one for the pivot pin.
I used one of my tool holders for the mount, Added a little light duty spring to assure the cutter would drop into place.
Tool uses carbide tips that I have several of. Now I'm not afraid of treading any more. I only wish I didn't have to change them damn gears to do it.
