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.

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

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.

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.

Subject: | DynaVibe prop Balancer |
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.

Well it's happened to me after just 164 Hrs of flying! The right side step is cracked
almost 2/3 of the way around with just a little bit of metal holding it
together on the outside edge. Looks like I'll have to break it off the rest of
the way or it will fall off during my flight to/from Lakeland tomorrow or back
North on Friday (Daytona to Hartford CT). I don't think it's repairable so
I've ordered a new one from Van's. They seemed to think that others having this
problem have beefed up the steps to keep it from repeating in the future.......

Mine appear to be still good after 920 hrs TTAE. What is the "Bubba

After discovering that mine was cracked two years ago --- 2/3 of the way
around also, I drilled the rivets out, took it down to my local professional
welder. He looked it over and said he'd advise against using any
reinforcements like gussets, etc. He rewelded it. I had it powder coated
again and it's been just fine since. Based on my experience, I'd have it
rewelded. Match drilling all those holes would be a bitch. Maybe you
should think about wrapping a reinforcement around the break like, damn I
hate to say this, duct tape to keep it from moving and getting any worse or
falling off in flight, until you get home???
