Brent, a nit picker??? ;) Quoting Chuck Hards <chuckhards@yahoo.com>:
Actually, everyone forgets to subtract their edge bevel. Most folks are surprised to find that their clear aperture is sometimes almost 1/4" less than the stated size. My own, old, old 17.5" mirror has a clear aperture of ~17.35" when the bevel is subtracted. I'd be willing to bet that Daniels isn't a true 17.5" too. Hope that doesn't ruin his day.

Brent, you are a nice guy but a hell of a nit picker.
I just lost interest in this thread, pretty much completely.
