Can anyone (calling DR Doug) tell me the thickness overall of clutch plate for a 1924 Hudson.

Thanks in advance.

    Les, you must not exceed .2100" overall thickness rothe clutch will not disengage. There 312 corks on these beasts, and the protrusion is only 1/32" either side of the plate, so a lot of cork goes to waste!

    Thanks Geoff,
    Gee Hudson mucked around with the thickness on different models makes one wonder why.

    Les, all the multi-plates on Hudson Super Sixes and Essex Four and Sixes had the 1/32" clearance either side, and once they changed over to single plate system they were all 1/16" clearance. Of course as you know, the corks have to be compressed under heat down to that thickness to be long lasting. I had two weeks over your way last month, but was helping Stephen build a room on his house, so it was a working holiday and didn't have time to check you out. Hope things going okay with you. Best wishes,

    Geoff, can you provide more info on how the corks are compressed under heat? Thanks, Barry

    Geoff,

    As you know, we here in Sydney have done for many years used the discs as they use in the automatic transmissions, they have worked 99.9% with only one complaint, I have had one in the '42 for 22 years and still going strong.

    Barry, the corks are trimmed off to 1/16" thicker than the required finish thickness and clamped together between two flat surfaces, and heated to around 100C and the clamp tightened until the thickness is as required - 1/32 for multi and 1/16" for single plate. I use a diss-assembled pressure plate and flywheel for this purpose for the single plates, and have borrowed a clamp made of circular saw blades ( real heavy sawmill type) for the multi plates. I made up a 2"angle-iron top and bottom for the clamp with a threaded rod through the centre.
