Creating new rubber rings for CDM hubs

johnm · 25th September 2005, 09:37 PM

Hi there!

Has anyone any idea what I could use to create new rubber rings for worn CDM4 hubs? I believe the original black rings are made from nextel (according to some on Naim forum).

The rubber ring was extremely worn on my CDM4/22 on my Naim CDI (bought second hand - looks forth hand!!). I removed what little was left, and created a thin shim of rubber (similar to what Philips used in their CDM2 transports) cut to the correct size and cut-out from a kids party balloon!! It's quite thin and does the job pretty well, but still not as thin as the original nextel ring.

Has anyone any suggestions where I could get some very thin rubber from - must be fairly 'grippy' though to stop CD from slipping. Perhaps a silpad cut to size might work well?

Any ideas?

Cheers!

Hi John

Try a solution of liquid latex painted onto the hub.

This available from most hardware stores

Cheers

Whenever I have worn rubber rings or belting, I always visit the hardware shop that sells "O-rings" . Generally, these are oil resistant and also comes in all shapes and sizes.

Thin natural rubber.... hmmmm let me think...A rubber maybe. Tell us what sounds best, Durex, ribbed, studded... Hehe, this could be the most fun with these other then their intended use!!!!!

hahahaaaaaaaaaaaaaaaa! I was wondering how long it would take for someone to say that!!!! :-)

I did actually (only for a few seconds mark you - honest!!) contemplate it but think the rubber is too smooth!

I see a market oppurtunity here - audiophile rubbers :-o hahaha!

wearing one while listening to your naim will improve the sound as it damps your own vibrations

Similar effect with my Arcam / Naims, honest.

I'll sell you some audiophile ones, regular type but cryogenically treated for extra stiffness and everything in line ....
