Hi All,

I'll soon be parabolizing for the first time.  For my first project, I
picked 8" binos. Twin f/6.3 Newts

Any tips on how not to change the focal length too much?  I suppose doing
it right the first time is one suggestion.  Other suggestions would be
helpful too.

Should one ever cold press on one mirror and work the other?

My 2 laps are 0.8 D, and the slightly oversized one I used for getting spherical.

I'll try to add some more pics to http://j-engineering.com/ATM as the
project continues.
