I concur.  I've done about 20 hours just trying to get a 1/4 wave sphere
out of that little 4.25" mirror I've been working on.  I think I've
migrated thru just about every surface defect in the book: turned down
edge, to zonal rings, to hill with crater in middle and turned down edge,
now to turned up edge.  I keep repeating to myself that this hobby both
requires and teaches patience.  I'm close though; any day now...

>>>>>Ah, Yes.  Easy to test is right.  I labored through
probably 20 hrs of
figuring to get a good sphere 8" f/15.  I wanted the best reference sphere
