You had made mention of the prop being set at a high pitch angle, and that you were going to reduce the pitch thinking that was part of the prop oscillation problem.  Did you reset the pitch angle?  If you did then apparently that was not the problem. 
 
Hi Bob,
 
Yep, I changed the pitch from 15 degrees at the tip, to 10 degrees, and it made no difference.  
 
FWIW You might give some thought to adding mass to the engine.  This might be a situation where you could be adding weight to the wrong end of the vibration problem.  
 
Adding mass would be like adding a heavy flywheel, or the missing rotor, but I'm not sure I follow how it could be adding weight to the "wrong end of the vibration problem."  
 
I like the weather station,  for some reason I thought it would be warmer in Florida :>) 
 
Despite what many people believe, not all of Florida is in Miami.  It's a big state, and we hide the best part in the panhandle.  Shhhh, don't tell anyone  :-)
