I grind occasional mirrors and I know at least one other grinder who might be interested.? But we'd want to see some good results before sacrificing a mirror!? ;)? Not many people grind their own any more and I don't know how often people get their mirrors recoated.? Alan Ward at Moonward Coatings in Sudbury was doing them for many years with some intermittent gaps due to various reasons.? I'm not sure if he is still doing them but there is a website giving 'current' prices.

Hi Everyone,
I've been toying with the idea of coating my own telescope mirrors. By coating, I mean vacuum physical vapor deposition with aluminum and some kind of SiOx overcoat.
I might be able to acquire an old commercial-grade coating system, with an ~18" or so diameter chamber. It's been sitting unused for at least a decade, maybe more.
If I had the thing up and running, would anyone be interested in having their mirrors recoated locally (I live downtown Ottawa)?
I've never done this before, so it's definitely going to be amateur quality (at least initially).
Thanks,
-Adam
