Grinding your tool
Folks,
Many years ago I bought an 8 inch mirror grinding kit from Astro Optical in Sydney. It was a very comprehensive kit, and came with two full thickness 8 inch blanks.
I started out and did many hours grinding and now have the first grade abrasive done, and have a mirror with the right depression depth, and a tool with the corresponding peak.
Now, I see this as a bit of a waste.
Is it possible for me to finish grinding from here in with a different tool? One that isn't another 8 inch blank?
Could I then feasably use the 8 inch tool I have as a blank for another mirror?
Cheers,
Jason.
