Liam,

Acetal has been used before but has little or no compliance = very hard noisy ride.

nylon?

bit hard, but has some compliance.

silicone?

comes in different densities, i think.

Nylon is hydroscopic (absorbs water) so it would vary its compliance depending upon himidity, not ideal really i suspect it would wear quite rapidly.

I used Delrin
