Hey Siegfried,

Does the loose nut have a name?

Siegfried

I have a bug up my butt to grind a 4.25" schiefspiegler. What do you think? I'd be starting with about 180 grit.

I have a couple of old plate glass pieces. I wanted to see if Vaughn has some cervitt or zerodur or other low expansion glass.
