[ATM] grinding with tool

[horace r davis]

I started grinding my 16 inch mirror. mirror on top which should deepen
center I have between .005 to .008 to go to reach .200
it appears most of the grind is in the outer 2/3 not in the center is
this because I have not reached truly spherical shape. Am using 1/3
stroke over center overhanging mirror by about 3 inches. the outer titles
have made contact first I cased the tool on top of mirror.
