Hello All:
Cliff said in part:

        I have not built a rotary yet but have studied their design.  They
are EXTREMELY DANGEROUS devices, especially if you spin them up over 5000
RPM which some folks do.  The centrifigal forces make them a lethal weapon.
Perhaps one of the experienced rotary folks can step in here and discuss
design a bit.  A couple of folks on list are experienced machinists who have
built real masterpieces and understand the need for safety.  (Ed, Dave,
Richard, Bill, Greg, D.C., others step forward at this time.)
