Bill,
I've gone the "Dyna Beads" route. They are sold by Innovative balancing
www.innovativebalancing.com They are very inexpensive (I mean $3 bucks
or so for an ounce) and dynamically balance your tires whenever they are
in motion. A friend put them into his tires (tubes) and his shimmy went
away. On the lightning tires you would only use an ounce in the nose whe
el and 1.5 - 2.0 ounces in the mains.
I'm putting them in one tire at a time to see which tire, if any stops shi
mmying. Installation was a breeze even with the 90 valve stem.
Right now the nose tire has them in it, but I haven't flown taxied it yet.
.honey do's more than Murphy. I'll be testtng it out tomorrow and will re
port results. Then the right main; followed by left main
Their web site does a good job explaining the theory and technical aspects
of the ceramic beads. It also lists several good testimonials.
If this works,
Bear

Hey Bear: I wish you better luck than I had. I put the Dyna Beads in my RH
tire because it is the one always bouncing. I put about 1 3/4 ounce in the
tube, and my bouncing got significantly worse. I have now put a 10 ply
Michelin tire on and it is significantly better, but it still tends to bounce
at about 20 mph.

Gentlemen:
I know that this has been discussed many times on our site. Would like to
present the nose wheel shimmy, just in case someone has had additional
experience.
I fly a 2005 Esquil, that is Lightning cowl forward and all three gear
legs.
There is no nose wheel shimmy at take off, but often becomes rather severe
on landing after I allow the weight off of the main gear onto the nose
wheel. By this time she is going rather slow, about 35-40 mph. The shaking
will stop at about 15-20 mph. And does not recur during taxi operations.
What is interesting is that even when the plane is not moving, should I take
the prop and put lateral forces i.e., right and left, there is a clanking
noise as if the tire is rubbing against the wheel pant.
I have checked out the nose wheel installation, changed tire pressures,
balanced all tires, changed tire brands; however, the symptom remains
unchanged.
I am out of ideas. Have learned to live with the shimmy, but this seems
to be a mechanical mystery. Any suggestions would be greatly appreciated.
