[ATM] Schmit corrector grinding

[tillerman1@videotron.ca]

After a long on again off again (family and work kept getting in the way) attempt at making a schmidt camera, the tools and vacuum pan are ready. The tool has been ground to the correct sagitta at 500 grit.
The sagitta of the tool is less that the sagitta of the corrector on the vacuum pan as per the spreadsheet.
My question is:Do I grind the corrector until the tool is grinding the center of the corrector?
The pan gets lapped this afternoon in preparation for putting the corrector under vacuum this evening.

Clear skies and good health
