Re: [ATM] my 20" mirror edge condition

If you have some way to spin it, like laying the mirror on its back on a
potters wheel, or a lazy susan, you can tape some silicon carbide sand
paper or emory cloth to a belt and hold it against the side while you turn
the glass against it.  Should only take three or four hours to smooth it
out.
