Hi Guy,

It's sounds not good if you have that kind of experience! Mean I am now 
grinded my new lenses with carbo 220 and seriously have thought to 
trepan them after polishing. My own experiences with a biscuit cutter 
and loose abrasives have been quite positive. Only time consuming. Last 
time I managed to break off one small piece from the center edge of the 
R1 surface. But then I trepaned the lenses after 220 carbo. To use a 
diamond cutter I know nothing.

Rgds,
Aki
