Haven't read ed's link yet, but does it have any "give" to it, is it
compressible at all?

UHMWPE is both compressible and elastic -- A LOT compressible, but not a
lot elastic. FWIW, you can usually let the compression-set between
fixed-spacing parts determine the elastic point for you, since it will
deform under pressure, then stop with some elasticity left to recover
back a few tenths.
