The prop biz was not silly to those of us that had the shakes so bad as to almost
make the aircraft unflyable. To date I have not heard a good explanation as
to the cause of the shakes. So far we only know that going to a 3 blade fixed
it in every case.
I'm jealous of those who have a 2 blade and no shakes.

Getting Silly?
I actually think this is an excellent discussion.
Great feedback from those that have been there.
No one so far has said that they had the shakes and changed isolator
mounts. I am hoping to provide some data here once I work it out with
Hartzell and Lord or Barry.
Many thanks for all the posts on AND off list. Keep em coming.
Best,
Mike

Hi Mike,
I understand from talking with John Harmon that the Lord mounts work better
than the Barry mounts. I hope you can work out a good solution with Barry.
The 2 blade propeller has a 2nd order harmonic that isn't present with a 3
blade propeller. That is the vibration you are trying to isolate.
A 3 blade propeller has a 3rd order harmonic that isn't present with a 4
blade propeller.
I'm planning to use the MT 4 blade Rocket propeller on my Harmon Rocket 2.
I also have the Lord mounts.
Regards,
Jim Ayers

I agree. Improving these airplanes isn't silly. If nobody bothered to come
up with new ideas or improved these airplanes there wouldn't be HR2's or
F1's or Super-8's. Or even RV's for the matter.
Regards,
Bob

One out of 11 still sounds high to me, I don't want mine to shake. So
now I am starting to wonder and need to ask this question: For those of
you who are experiencing the shake, is/was your prop a new Hartzell, or
is it from a prop shop?

Yeah, and I didn't know about all these problems. It was an education, silly
or not. Thanks, guys.
