Johnny Thompson:

Will you work with us at Vari Prop in establishing criteria for a vibration test?

WE are prepared to start right away. 

What do we do first

  Milt and all

  I have been involved in vibration testing on airplanes and helicopters for over 35 years.  It is a very simple and safe process that yields excellent results. Testing is done mostly in R&D while smoothing the vibrations caused by props and blades is a normal everyday occurrence that can be done in a couple of hours. I still have  my vibration testing equipment and can perform test on any type of engine and prop. Correct that, can't test the Rocket Velocity.  This prop manufacture probably has his own testing equipment.    Johnny Thompson   14az at mysprocketmail.com

    Milt,

    I thought Sam DaSilva said that he would test it on his V (IO-360 180HP no/Counterweights, and I could on my V (IO-360 200HP w/Counterweights) since we are in side by side hangers.  Sam has more V test time than anyone I know going back to original Danny testing.

    Larry Morgan, owner of Vari Prop, told me he is interested in securing 
    vibration tests with his prop on a Velo.?

    Who in our group has the knowledge to offer expertise in an acceptable 
    method of  testing.

    Who in our group will offer a Velo.

    Larry Morgan will supply the prop.
