The grinding rest in MWE 109 calls for a 1" platic ball. Does anyone know where I can get one?
Thanks

I would think that turning one up from bar stock may be the easiest option. Unless anyone else knows a source for these...

I think the surprisingly precise balls in roll on deoderants can be found in
1 inch size, if the thought doesn't put you off!Scrim
Stewart They're usually readily available at the various ME shows - I think Proops had them at the recent Bristol show. Send me a snail mail address off list and I'll send you one. --

This thread got me wondering how steel bearing balls are made. I can't imagine how spheres are routinely ground by the million to fine tolerances on radius and surface finish.
