Hello Bob, count me in  ;o)

see 

http://www.cablevision.qc.ca/astro/alex-36ins.jpg


36" dia and 5" thick, 120 pounds of fully fused, strain free glass,
f/4 molded faceplate, 5/8" thick, flat 1/2" back (seen in photo)
can be polished/figured without printrough or astigmatism

fusing is the way to go !
