View Full Version : 3c collet closer dimensions

06-07-2001, 07:18 PM
Looking for a drawing and/or information on 3c collet closers. No, I don't want to buy one, I'd like to make it. If you could help me with the details of bearing surface diameter and entry angle I would appreciate it very much.

This page http://www.loganact.com/tips/collet.htm has a little information. Not enough though....

I have a drawing or two in AutoCAD of my collet closer. I have a 9" South Bend. Its not a lever, just a hand wheel type. If you want me to dig them up I will. Email me if you want me to find them.

I just made a 3C closer, and I was referred to www.zagar.com (http://www.zagar.com) for dimensions.
MUCH more info that the Logan site. Suggest you look there in the collet section and I think you will find everything you need.

I made the closer piece from the dims on the site before I got any collets, and it fit perfectly when I was able to try it on a collet.
