Steve:

The coefficient of friction is much more related to material than to
surface finish. Consider a rubber eraser -- very smooth, but very high
friction. IIRC the friction material in Swee****er's Lofrans windlass
was a phenolic/Bakelite/Tufnol type of stuff, much less friction than
a brake or clutch lining.

1) Is the new friction ring the same material as the old one? Are you
sure?

No. the brake material is much courser than the original but it was all they
had available in that thickness.

2) Is the metal surface against which the friction ring rides smooth?
Really smooth, even after your incident?

The drum surface is chome plated and is very smooth with not even a scratch.

I'm considering taking it back to the clutch brake shop and ask them to sand
it smooth. I'm sure they must have some form of surface sander for that type
of business.

Thank.
