Surely there is some sort of auto motive or industrial clutch material you can apply. Something that will let you ‘cut’ it into shape - or bond pieces around the surface to give enough contact for a good grab. Possibly some industrial grade tanned leather would work again if it is stout enough to handle the wear. Interesting challenge...
Clutch on thicknesser
I have an old (35 years) Scheppach thickness and surface planer, (250 mm) which is still working excellently, and has done so for the last 16 years that I've had it. About 8 years ago I needed to replace 2 of the gears in the roller drivetrain, which I obtained from Scheppach in Germany. I noticed that the material on the clutch plate was quite worn, and I decided to replace it with a ring of suede leather, which I carefully cut out and bonded to the plate with contact adhesive.
All went well for a few years, or so I thought! A couple of years ago I noticed that the rollers were still turning when the clutch was disengaged while surface planing. I opened up the drivechain and found the clutch pair were firmly bonded together. I put it all back to for another day, as it wasn't causing an operational problem, and I had more urgent things to concern me.
Well with lock-down, "another day" has arrived! I decided to tackle the clutch, and with great difficulty I managed to separate the components, and found that the leather was all scrunched up, and that some sort of gunk was binding the shaft that the plate moves on. Now it is all cleaned up, and moving beautifully on the shaft. But of course, now I have no means of engaging the clutch.
I realise that I will have to find someone who can professionally bond the right sort of material to the plate, but until things open up here, that's not likely to happen. So I am hoping that someone might be able to suggest a temporary fix for me - or am I "clutching" at straws?

Success at last - (at least I think so)
I did some tests with the Pratley Wondafix, and the results looked good - I applied it to the clutchplate and let it cure 24 hrs. I have now re-installed, and everything is working as it should. The clutch engages with no sign of slipping, and now for the first time in years, also disengages.
So thanks again for all the suggestions - I might need to re-visit some of these if this fix doesn't prove long-term.
