I can find out from Bill Bainbridge of B&C at Airventure. The shop he
recommended found a several built in problems with our Kelly rebuilt main
alt. when they balanced it.

So how do you get your alternator balanced? non-aviation shops won't touch
them and aviation shops don't want to open them

Ed Martin's legacy is smooth. Mine has had a lot of annoying vibes as you
describe but virtually all have been removed with lots of cowling

be a wicked source of vibration and it is almost in the same plane as the
prop.
The problems I had originally were in that freq range and visible at the
wingtip also.

Has anyone definitely flown a vibration-free IO-550 Lancair (or TSIO-550)
with *any* propeller? And by vibration-free, I mean it is free of
low-frequency 10-20Hz stuff, not the normal noise of flying. What I'm
wondering is... is it the 550, making such vibration with *any* propeller?
