Tormach Tts Er Collet Holders?

[RJSakowski]

Thanks for the additional info and links.

To clarify, I wasn't thinking of making ER Chucks. But was thinking of machining out some custom holders. A couple of basic End mill holders, and I saw a neat project where a guy built a touch and edge finding probe for his TTS system. Yes, with the appropriate flange. He hooked it into EMC2 (Linux CNC) which I was leaning towards for my eventual CNC project for my mill.

My dial indicator has a 5/16" shaft so I use a collet and chuck for it. It would be nice to free up the collet chuck so making a custom holder is not a bad idea. Concentricity is not an issue there. Ditto for the edge finder.
