Cork with copper for clutch plate inserts
« on: February 27, 2016, 12:39:57 PM »
Hi,
A friend of me is searching for a 6 mm cork plate which includes some 'copper' for making inserts for his clutch plates. This material is difficult to find here in belgium and somebody told him this can be supplied in the uk. Has anyone an idea of a supplier for this cork? Thank you very much for helping us to find it.
Kind regards
Guido

 I think you mean "asbestos" clutch plates.
Northern France, 100 miles from London, as the crow (or the swallow, or any bird) flies.

I think both of you are referring to what we in the UK would  call "composite" plates, used both in modern clutch plates and brake linings.
Certainly no longer contain asbestos, and I may be wrong, but I think the flecks of metal that are in them , is brass.
Both in clutches and brakes they are now nearly always bonded too plates rather than "inserts" or riveted.

you need an old clutch plate from a wagon or other large vehicle that you can cut up to fit but this type of material is designed to run completely dry????
the type of material is called "sintered" and is used in clutch plates and brake linings (dry)

Hi,
I did some research on the web and found the correct wording for the material I
am looking for: organic friction material , but to find a good supplier of max 6 mm is however difficult. Hopfully someone knows an adress.

Thanks Thomas. I need the material to make those inserts. We have some old plates from a Gillet motorbike from the fifties where the inserts are in bad share. Those plates can't be found anymore.
Kind regards

As Ian noted, Guido, you need to find an old truck clutch centre disc as these will often have one good side with friction pads left that are over 6 mm thick. They are big enough to drill out the rivets and leave sections between the holes that will do your job. Brake pads would also work but I think they are too hard to cut - I've tried it.

Find a haulage workshop or commercial dealer and ask for the mechanic who rides a motorcycle - he'll help you out.
