Fellow RV drivers:

does anyone have any first hand experience with the DynaVibe dynamic prop balancing test set?� 



http://www.rpxtech.com/rpxweb/Dynavibe.asp

 

They are $1500 I'm kicking around the idea of throwing in with some other experimental owners and getting one.� I've had some trouble getting my prop balanced locally and for $1500 it wouldn't take to many interested parties in my EAA Chapter to justify it.� I just need to know that it does the job.

 

Thanks

Bill

You may want to go to e-bay and check out an EVA�2 electronic vibration anilizer C got mine for 450.00 C new thay run 1600.00 they are used in the auto ind.

How do you use the EVA2 to determine where to place weights on the 

spinner to balance the prop?  Trial and error or is there something that 

I don't understand about this analyzer (probably) that would tell you this?

This link has a pretty good explanation of the principles involved in  dynamic prop balancing.

Zero experience with the device but my local prop shop charges $200 and says he should probably charge more. Should not take long to pay for it.

Mike,

  

   I am interested in the vibration analyzer you had mentioned  about. I am trying to think it through and was wondering how you locate the  rotational location to place or remove the weight needed to balance the object  you are working on? I have not found any that have a strobe light included. Does  your kit have one or is there a different way obtaining this  information?

  

 Thank you!

  

 Chuck

Our EAA chapter has an electronic prop balance, EAA 105.  Not sure if it's a Dynavibe.  Email Randy Lervold



randy(at)romeolima.com



He will be able to provide details.

Thanks, but that is really not the information I need.  I already know 

the principles and how one does it in practice.  I just don't know 

enough about the EVA2 to know if it can be used like the description.



Possibly it has an output for a strobe and can be used exactly as the 

description you referenced.  If not, it could be used in a trial and 

error approach.  Check the balance.   Add a little weight somewhere and 

see if the balance improves or degrades.  Adjust weights appropriately.  

Fairly easy, but much easier with a synchronized strobe.

A typical dynamic balancer will place an accelerometer on the engine and a

small reflective timing tape on the prop along with a cheap light detector.

The outputs are sent to the balancer which using equations of vibration will

figure out where and how much weight to place on the spinner backplate.  No

strobe involved, and certainly no trial and error: it's all deterministic.

Once the weight is placed, it's measured once again to check the improvement

and job done.



Our RV club a year ago had a great presentation by a fellow who measures the

acceleration (vibration) both fore and aft, not just in the front.

Apparently this does a better job.



The principles of dynamic balancing are not quantum chromodynamics and the

equipment should be inexpensive, so no reason why these things should cost

huge amounts.
