Non-Standard 3C Collet
Other than making one is there any way to get a 3C collet in 5/8? I
know I could have one custom made, but that's silly. It wuld be handy for a repetive job I am working on to do the heavy operations on the big lathe and some lighter operations on the smaller lathe. The problem is I have it setup with 3C collets and a closer and I absolutely hate bolting on and unbolting a chuck on the small lathe or the mini lathe. Its just a big pain. Anyway, Is there any chance 5/8 is one of those out of spec sizes that just happens to exist anyway. Like 7/16 for ER16 or 5/16 for ERll. They are outside the spec, but they are commonly enough made that you can hunt around and buy them for about the same size as spec size collets. There is a enough meat on a 3C for it. It wouldn't go all the way through, but my 1/2 inch 3C collets don't go all the way through either. |

I've bought a number of 5C emergency collets and all had oversize pins, IIRC 3.5mm in 1/8" holes. Maybe they couldn't source the correct size where they were made so they substituted something close. |
