Compliance bush measurements?
mine are seized solid, and i'm a tight arse who happens to be an engineer 
does anyone locally (stoke on trent) have a bush i can have a measure of, or can anyone take their bush an engineering place and get them to have a measure? Won't cost anything to do, just ask a worker on the shop floor
want to have a bash at making my own poly complience bushes! Diy ftw!
I'll need accurate (to 0.01 mm) measurements of:
the outside diameter (the bit that actually is pressed into the arm)
it's length
length of the inner bush thingy (that the eccentric sleeve sits in)
and the inside diameter of the inner bush thingy
thank you please

Powerflex were, at my visit time, working on a solution for using poly in the compliance bushes.
Spoon don't (what I put in) and obviously OEM don't. This may be a bit of a bigger task than you have planned
Your terminology sounds shockingly similar to mine when on the phone to Powerflex feeding them measurements from a borrowed vernier calliper!
Thingies, whatsitmahcalled, jobbys and roundy bits.

i was planning to use 80ish durometer poly, frozen to make it machinable.
Regarding compliance - i think it might bumpsteer more with these in, because s2k's run a LOT of caster but i used to have a crx on a full set of polys with alot of caster and that was fine. I might need to change the suspension geometry from honda specs.
At least to me with my ham-fisted driving i shouldn't notice much difference!

Interesting project, keep us in on it.
Not saying you cant or shouldn't you obviuosly know your engineering...
Have you seen the oem part up close yet?
Its slotted and has to be the correct way around for 'give' obviously.

the oem ones are actually, although not at all glitzy, quite a piece of engineering imo.
They have steel linings within and the flexibility comes from the holes that only give in a set direction - i found myself looking at them with a fair bit of respect when i attempted to prise them from the wishbones i had.
I hope powerflex do devise a solution, aesthetically they would then match all the other bushes in my powder-coated wishbones, which would be corking from a bling pov.

Yeah i've seen the oem part, whilst swearing and hanging off a breaker bar to no avail 
lots of rubber bushes are like that, honda have been doing it for years - the rear trailing arm bush on most of their civics and probably alot of other models (upto and including ep3 afaik and probably most other models, read somewhere it was part of testing for the nsx (in the CRX) they must have just liked it) - the bush allows fore and aft movement which because it's a funky trailing arm-cum-double-wishbone allows changes in toe with braking forces! People swap them out all the time for solid poly too!
I can't wait to give you a progress update.. I just need some damn measurements! lol
