an old handbook

[Ken S]

As much as I appreciate vintage Tormeks, in a working shop I would opt for a newer model, although a low price would at least tempt me.......

Certainly, if it were local, at a low price, I would be over it for a couple of reasons:
1.  Wanted to do a manual water wheel for years and it takes up less space then the yard art ones I see.
2.  My understanding is the stone changed at some point between that one, and the 2000 model.  I would love to try the stone.

Based on the old handbook, the original Tormek grinding wheels were natural and had a finer grit. The change was to man made stones. For a while, both were available.

The manmade stones have a coarser grit. They cut faster. They may have more cocsistent grit size and are probably less expensive. The stone grader using the fine ide converted the man made stones to the natural stone grit. Clever.
