ATM figuring/fine grinding.

[Bob Hazel <machead@qadas.com>]

Well, after about 20 figuring sessions I am out of finger nails from
biting them off. I never really did start with a good sphere, it had a
central hill after polishing. Never could get it to polish out from the
center until I started parabolizing. Trying to get zone one to read what
it should has recked havec on the rest of the zones. Right now I am
minus .017 zone 2
minus .019 zone three
minus .001 zone four
plus  .024 zone five (did something really dumb to turn the edge.)

  So right now I am considering (well actually almost for sure) going
back to fine grinding in the morning unless someone on this list talks
me out of it. But if you all agree this is what I should do, what grit
should I go back to?

  thanks,
