Re: [FlyRotary] Rotating Assy Stuff was Re:
[FlyRotary] dy
Hey Leon
You talk about mandrels, are the
mandrels for balancing the rotors first??
I assume that you balance the rotors
first and then put the on the e-shaft and balance the
assembly.
Ken
Marv,
To answer you question about the flywheel, the assy is first
balanced
without a flywheel or clutch (assuming we are using a lightened
flywheel and
an auto rear counterweight). Obviously on a stock MANUAL
rotating set, the
rear counterweight is incorporated into the flywheel itself.
(Don't have a
pic of this).
Once this rotating mass is all balanced out, then the lightened
flywheel is
bolted to the counterweight and balanced out. Finally, the
pressure plate
is put on and again balanced out. Alternateively, the
lightened flywheel
and the pressure plate can be balanced separately on a different
mandrel.
Doesn't matter, the results are the same. Doing it this
way is quicker &
easier. Saves changing mandrels!!
The machine my Balancier uses is a Shenk. There must be
thousands of them
in engine shops around the Hew Hess Hay countryside. It's a
matter of
finding a shop who is willing to a bit of R&D, and make the
necessary
mandrel(s). "Aint' hard!! Not compared to balancing a
2 plane V8 crank
anyway. That really IS a "Black Art"
Enjoy,
Leon
