Milling Cutter Holders for Unimat

[Melkal]

Paul, thanks for the pictures and discussion. I am a newbie and inherited a used Unimat with limited accessories. It came with a faceplate and dog, a 3 jaw chuck, Jacobs type chuck, tommy bars, a few dull cutters, a "grinding hub", lathe tool holder. It's all been torn down and rebuilt and repainted. I've added a milling table, Unimat vise, vertical post for milling. I have been cutting, turning and learning how to square it up. Goal is to build a mini steam engine.

In learning to mill, I either use the Jacobs chuck or the 3 jaw chuck. The 3 jaw is the original, but out of round and I have not found a way to resolve that with filing or grinding, the jaws were buggered up. So, I'd like to fix that also. But, I just read this post about the collets which I did not know about, but that looks like a much better way to hold mills (etc) rather than the 3 jaw.

Thanks again
