does this take geological time?

DanFrederiksen,
Not at all. Figuring is pretty fast and straight forward, once you get the hang of it.

@Betube4 so how long did that one take? how deep a pit?
Berthold,
Great video! I'd like to hear your impressions as you work this significant piece of glass.
I'd also like to see your interferometric results.
I suspect that this will be one really nice telescope when completed.
Best regards,
