Now to find what to polish a lens with and where to get it. Any ideas people?

Willman-Bell has stuff for making astronomical optics, especially mirrors, that might be applicable to refractive lenses as well. However, I don't know where to find that part of their catalog online. Find them online and ask for a copy of their catalog, which lists those supplies.

I'm sure there are other suppliers, but I don't know them off the top of my head.
