Hi BillP
Didn't know if you are aware of this but this is one common technique that is
used to cast pipe, mainly large ones i think, They call it centrifugal casting
(imagine that :) ) We learned about it in a Manufacturing process class last
semester, had a pretty straight forward equation for calculating speed, I think
that 300000 rpm would be pretty hard to do, I don't know of anything offhand
that can go that fast. What king of g force are you looking for, most of the
normal centrifugally cast pipes spin at under 700 rpm, and they can get 50 or
more g's at the outer edge, if you are inerested i can lookup that equation for
you, don't have it right off hand anywhere. Also what are you going to do with
a see through aluminum cylinder?
