Expect so or one its relations
Was hoping someone had hands on experience
I think Stephan has a very expensive tool grinder maybe
Robin did a lot of work on his to get it performing adequately, they're probably good enough out of the box for mere mortals though. There's a big difference between a single lip grinder and a proper T&C grinder too, the latter being far more versatile (And expensive).I believe these grinders are clones of the Deckel single lip grinder, originally meant for (pantograph) engraving tools. Everybody and their mother sells one. Have a look at some US sites (maybe Grizzly, Travers Tools, KBC) as I am sure there is a more comprehensive set of instructions there than anywhere else than I have seen.
On YT, Stefan Gotteswinter and Rob Renz have some videos on their use.
