Brian,
Condolences. I feel like I've been kicked in
the groin just reading your story.
Over the nearly 1000 hours of my flying and
maintaining a 360 Lancair I've had some problems with minor shimmy.
As the strut accumulated time and wear, it became
much harder to keep from shimmy. Everything had to be just right to the
point that even certain tires were troublesome. I broke down and sent the
strut to Vern for overhaul and not long after, bought a new strut. The new
improved strut cured the problems completely.
I'm sure this is just another case of where I was
just lucky.
One thing that has a large effect in controlling
shimmy is the tension on the wheel bearings. ( I doubt you neglected this
as you were very thorough.)
Also, when installed, new bearings have a rapid
"break in" where after a few landings they loosen up and need
adjustment.
I'm really glad you were not hurt.
