Chuck, We need to adapt Patricks 8" lens to fit the Clark's 9" ring. Guy Quoting Chuck Hards <chuckhards@yahoo.com>:
A piece that thick won't be cheap (maybe if it's radioactive...).
Is this for a cell or endpiece? If most of the interior is to be machined away, perhaps a casting made from a pattern would be cheaper, and take less time on the lathe to finish...just a thought.

BTW, speaking of telescope parts, SPOC needs a piece of aluminum about 10.5" to 11" in diameter and 2" to 2.5" thick. Anyone happen to have such a piece laying around or know where it could be purchased cheap?
