[ATM] Schmidt corrector tools

[George Anderson <tillerman1@videotron.ca>]

I am about to finally start on my schmidt corrector for the 6" f/2
camera that I am building.
Tomorrow I'll trepan the blanks for the corrector (water white plate
from a scanner) as well as the blanks for the two tools.
The glass I have for the tools is 1/4" plate, is this too flexible?
Would bonding two pieces together with either pitch or "crazy glue" to
for 1/2" thick pieces make sense?
The sag for the corrector is very small (I'll check it with the
spherometer) so the amount of glass being removed is minimal, I was
thinking of 220 grit for "hogging" (shrimping might be a better term for
this amount) out the tools and then starting off with 400 or 800 on the
corrector plate (the tools would be ground to the same grit before
starting on the corrector plate).
