  • 3c collet closer dimensions

    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.

      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 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.
