Three Tormach Collet chucks should arrive from Little Machine Shop by Thursday.

I have some good news and some bad news.

The good news is that the Tormach ER20 Collet chucks arrived a day early from Little Machine Shop. Those guys are really great and I really should use them more often.

The bad news is that the Tormach collet chucks are different from the Novakon collet chucks that I have. The Tormach holders have a much shallower undercut than does the Novakon holder, as shown in the second picture.

This means that the R8 holder that I had to grind down in order for the Novakon holders to seat against the spindle face will absolutely not work for the newly arrived Tormach holders. There is a good .050” that has to come off of the R8 holder, maybe even up to .090” or .100”.
