[SEL] FM Mdl Z Style C 3HP

[Reg Ingold]

If you show 1/16th variation, that will give you a 1/8th runout. And I bet
it looks awful !! It should pull back ok.

> I took a tape to the flywheels and measured between them in different
positions.  At most places it measured 17-1/4", but there was a place that
it was 1/16th more.  Is that enough to assume a bent shaft?  And to let you
know, it is only the one flywheel that wobbles.  The other seems to run
true.
