Hi all
I was among the group that got a 4.25" blank from Rob O'Toole`s order.
Thanks again Rob.
Well, here`s the plan, please pass along any thoughts.
I`m going to grind this to an F5 and finish it spherical. After coating 
the back will have a fine threaded machine screw epoxied to it...in the 
center. The mirror mount will be a ring of ?felt ?carpet to support the 
outer 1/2, and the screw will go through a circular piece of plywood, 
with a nice big wing nut on the other side. The parabola will be tuned 
in at each use, kinda like a star test but the figure will be tunable.
Well, that`s my latest mad scheme, all comments appreciated. Idea came 
from an old S&T or Astronomy, long before the astronomy bug bit me for 
real.
Thanks
Rodg
