Re: REFLECTOR:Nose wheel shimmyAnother way to do it is to pull the tire, and
the axle and support the axel/tire assembly on the edge of 2 single edge
razor blades- there will be almost no rolling friction on the almost perfect
edge- and add the weights until the tire no longer wants to find any
particular favorite place to rest.

Subject: Re: REFLECTOR:Nose wheel shimmy
My nose tire was way out of balance as it came. I was able to balance it
by jacking up the front of the plane and spinning up the tire with an air
powered die grinder. I used one of those 1" drum sander attachments without
the sandpaper drum installed. You can really get that tire spinning! Then
using stick-on lead weights and trial and error, I was able to get it to run
smoothly. I used double stick tape on the weights until they were where I
wanted them and then used the self adhesive tape on the weights. So far the
weights seem to be staying put.

When I had shimmy I also had an out of balance front wheel. I removed it
and reinserted the axle in the bearings. I then bought two aluminum angle
irons about 3 feet long and set them up on my workbench, and levelled them
in every direction. I placed the wheel between the aluminum L's supported by
the axle and watched. The wheel turned. I got some aluminum weights from Big
"O" tires and applied them on the light side of the wheel, on the inner side
of the wheel. After installing about 3 weights I had a balanced wheel and
tire.
The weights are held on by adhesive that is on the weights when I got
them. None have dropped off, due I suppose to the fact that they are held on
by centrificial force when the wheel is spinning.
This in addition to keeping the fork tight seems to have resulted in a
very much smoother front gear.
I suppose this is not as precise as spin balancing, but it worked for
me.
