[ATM] 15.5 One more hour, one more picture

First off I want to thank everyone for writing and commenting, pro and
con.  It is great to see some argument and discussion going on.

I added another small picture to the line up of three at

The one on the far right is after thelast hour of grinding.  Looking
pretty good.  That last spot on the right is very slow.  I was concerned
that it may be too deep, or maybe a turned edge from the slump.  I got out
the caliper and did some cross checking around the mirror.  If it is a
turned zone it is a very small one.  I can measure to 1/64th with the
caliper and I could nat see a difference regardless of how I measured
across that zone.  That said, the edge thickness is still right at
12/64ths or 3/16ths.  So even with the amount of grind I have done I have
moved very little glass.  I think that form was a little truer than I
thought.

My sister found me a glass edger with a new diamond wheel on it at a
garage sale.  So now I can edge and bevel in style.
