Hi Rich,

I just go back to 1/4 to1/3 strokes TOT MOT TOT MOT center over center until
a Foucault/Ronchi test says it is a sphere again.

Would someone with experience describe the strokes I need to bring an 8" f8
mirror back to sphere after having  been figured too deeply?

MOT? TOT? center over center or W? Light pressure? Hard pressure?  Long or
short stroke?
