Well. Write-up, FWIW. In case it’s useful.
Took the clutch apart, using the opportunity to re-pack the bearings with grease.
I scraped off the outer surface of the friction material, taking care, it’s probably fragile. I also cleaned the cast iron outer cone, and the inside surface if the friction material, scraping gluey residue off, and the light alloy inner cone, dressing it lightly and evenly with a flat file.
It seemed a good idea to put the chemical metal on the alloy inner cone, so I did that, as it was easier than putting it on the friction material, wiping on a thin layer with a plastic spreader, then using a coarse hacksaw blade as a notched spreader to make it an even depth all ’round.
After that, I put the assembly into a press and applied light pressure until the chemical metal began to squeeze out.
Tomorrow I’ll get it out and fit it It will be interesting to see what happens if I can get the thing started. This is the machine with points, which is in rather better condition than the other one.
The thought occurred that it may have been better to use “Gun Gum”, use a couple of bits of flat bar with holes for a bolt through the middle, and a couple of spacer blocks to allow the cast iron and alloy to be pulled up, then when all’s ready, stick it in the oven on “low” for an hour or so before turning it up to 200C for another hour.
We shall see.
Quiet in here…
