Hello all,
Since things are going well with the polishing this time around,I figure it is time to start getting more information, so i was wondering if anyone had any insite to parobolizing a 10" F-6 mirror, I have read some on it, but am confused, according to one instance,for a 6" F-8, i beleive it was, you do something like 72 strokes in a specific way to go from spiere to parobolic..... but, for example... do you still turn the mirror and lap as in the polishing stroke....seem to me you would, but by reading about it, it gives the impression you do not.....got alot to learn about this i guess......still have many hours of polishing to do... just want to make sure i have everything down before i get done polishing, your help would be appreciated, Thanks
