Have you considered useing aircraft turn bukle bolts?
I'm only loosely following the list these days due to a lot of work, so
maybe this has been discussed before. But I've been thinking: wouldn't
it be possible to do away with the pivot altogether and replace it with
a spring leaf? I make springs professionally and I think it would be
possible to replace the upper and lower bearings with either two thick
leaves, or a single wide but thinner leaf that would have an angular
range in the order or +-15 degrees on either side, perhaps more. What's
more, it would also strengthen the self-centering effect, as the
spring(s) would fight any turning effort as a linear function of the
turning angle. Unaided, the springs alone couldn't fight torsional
efforts very well when turning, so perhaps a pair of small guiding
bearings or bushings could be added, but at least the springs would bear
the entire load of the rider, which the bearings wouldn't have to withstand.
Anyway, I've been thinking about this for a while. Maybe it wouldn't
provide a small-enough turning radius, and perhaps an additional static
turning effort wouldn't be desirable, I don't know, I've never ridden a
Python. Perhaps one of you specialists could give me an opinion?
