I have progressed to 120 grit and have most of the pits from the 60grit. 
But the Sagitta is slowly getting deeper.  If I switch to TOT will this
flatten the sagitta out a bit?  I am aiming for .012(on the spherometer)
and I am currently at .0132".  This will give me a ROC of 116" 
instead of the 128" I am looking for.

Some new pictures up on the mirror grinder page below
