"Excessive" vibration will not be solved by dynamic balancing.  Both engines??  Check engine compression and propeller blade angles.  Good luck.  jb

Good Morning Lloyd,

  

 I may be getting in on this late, but have you recently had work done on  both engines?

  

 Vibrations such as you describe are often caused by a very conscientious  mechanic who tightly secures every wire, hose, cable, and shaft that he can  find. That stiffens the engine's connection to the fuselage and occasionally  transmits vibrations at resonant RPM ranges. 

  

 The reason we have flexible engine mounts, hoses, and wires instead of  solid mounts and hard lines is to provide enough flexibility to allow the engine  to wiggle when it wants to wiggle without wiggling the airframe. 

  

 Just snipping a few Ty-Wraps may do the job. <G>

  

 Happy Skies,

  

 Old Bob

Could it be a misfire? Injector or magneto?

I got my prop back from the prop shop and the vibration was bad enough to do damage to the spinner and back plate. We were 50 miles off show when we discovered it. I managed to get it home and took it back to the prop shop and found the blade they had replace was too long and out of pitch. Mine did not vibrate enough to notice but it sure did some damage.
