glass grinding/polishing

om...
I have a couple hundred glass prisms (right triangular: ~1.5"x2"x6")
that need to be cleaned and polished. The wide side has a mirror
coating that needs to be removed. Most just need polishing but some
need some grinding first. The local glass beveling shops are not
interested so I might have to do it myself. What would be the right
equipment to touch up that large a flat surface? The horizontal
grinders look nice, but I hate to spend over $1k and then still have
to do it myself. Any suggestions would be greatly appreciated.

Thanks in advance,

Brian

Where are you located?

What application will these prisms have once they are polished? Are you
looking for perfect optical flatness? What tolerances?

I know some people in the photographic lens mfg business that have the
equipment to do this...

Did your local shops quote you a price? Unless this is top-quality optical
glass, I'd bet the cost of repolishing all three sides (and ends?) of the
prism will exceed the price of new replacements from Rolyn Optics or Edmund
Scientific.
