View Full Version : 3c collet closer dimensions
06-07-2001, 06:18 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 think that i would like to have my colletts in hand & custom fit....IF i remember ...gary reisdorf in hms wrote a GOOD piece on making own colletts, used hardinge book specs .....before 92-93 or so.might have been 3at .think it WAS 3c. if all else fails , i think i can pin it down for u.
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.
