BTW, 15 dollar 12.5 inch Pyrex blanks are the rough equivalent of
finding an almost new, mint FT-1000 MV Field, loaded, for 100 dollars,
so there is your luck!

Excellent Mike ...I made a 4 inch reflector yrs ago ....this fellow had
slabs of glass he got for free ...we made up a cutting saw out of brass and
with patience ...a drill press and some slag ....we were able to cut out
blanks. Grinding and polishing were fun ...but I gave the scope away years
ago. About 4 yrs ago I bought a 6 inch reflector which I have a ball with
...... when I have the time ... We are worried about BPL qrm ...funny that
the same hold true re light pollution for the astronomy set.
