Re: Making adjustable strut tops...

LOL, thanks for the link  saves me finding it..
i basically used a turst bearing below and above the plate (2x 5mm random aluminium sheet). the spring top is squished between the shock rod and the strut top and the top nut.
basically, it does work.
it is not ideal as if the nut is too tight, it can actualyl stiffen the steering up.
the ally plates are starting to bend.. after 4 or 5 years of service (or is it 6??)
i also had to grind off some of the shock rod to allow the spring seat to mount further down, since the total thickness of the bearings was greater than stock.
i think a good design would be...
spring top hat free to move up and down shock rod.
thrust bearing above this (some AM ppl do this) to take the weight. thin poly bush (5-10mm?) above this to reduce harshness.
then shock rod that tightens onto the spherical bearing.
only needs to be spherical to allow for offaxis movement. self aligning ballbearing could also be used. the teflon lined cushions things a bit, as metal to metal would wear faster.
i saw an awesome bearing a while back. basically a thrust bearing, with a self aligning base (like hemispherical base). rated to something like 200 tonnes  was a big sucker 
anyway, the point is. even a shit setup will work. anything you do to better my design has to be a good thing
oh, i'd also not really bother with making those slots to adjust the position.
a carefully shaped top plate with a few different sets of holes will suffice.. if the bearing plate mounts uder the top plate, then so easy to just swap out the top plate for major alignment changes....
