Banquo, to handle the tt I remove the platter and turn it upside down on a large flat bowl that is covered with a dish towel. The washers are about 5/8" in diameter and 3/32" thick. They will raise your platter a tad by raising the entire motor. That gives you more leeway as to how tight that bearing thrust plate screw must be. Not tightening it too much is rather critical for clearance as well as proper alignment of the motor components.
Lewm, the 1/16" neoprene bonded to 1/32" steel do not make for a spongy mount especially if they are torqued down. Your point is quite valid but my ears tell me this is better. Psychoacoustics no doubt but c'est la vie. Anyway the washers that JVC used, being two metals and thin are a pain in the ass. As Banquo found out (and I did too) they tend to get lost in the machine.
