Belleville washer or 2 should solve the problem or a cork facing.

I would think some cork that is spring loaded it worked fine in the old motorcycle clutches.

Add a gland and fill it with PTFE plumbers tape self lubericating last well on my steem loco .

Noitoen:
Make a disk out of copper 1,5 mm thick and use a pair of hard disk magnets just like it was a disk brake caliper as close to the copper as possible. you will bee amazed with the drag it creates. I think some "vent" holes around the disk also changes the amount of drag. This is caused by eddy currents generated with in the copper when it moves in the magnetic field.
