This is going on a boat in salt water. Steel would rust and there would
be a big glavanic corrision problem at the stainless/bronze interface.

Getting back to METALWORKING ...

Is there a *reason* you're not making this out of bronze or steel?
Just because there was a plastic piece there *before* doesn't
necessarily mean you gotta have one now.

It seems that about half of you wear concerns and UV deterioration
problems would go away with a good bronze or steel sleeve bearing.
(Might help solve the vibration issue too.)

My two cents.

I have a KISS wind generator wind generator that develops vibration
at certain wind speeds. The problem is that there's a PVC fitting
that goes over a 2" stainless schedule 40 support pipe that is loose
fitting. I
want
to machine one with a sleeve bearing on a lathe and make it out of
plastic.
However, I really don't have any experience machining plastic, I've
been looking at www.mscdirect.com under Raw Materials/Plastic
Material/Rods for 3" material. To keep costs under control I'm
looking at the following:

Nylon
Acetal
UHMW
LDPE
HDPE

Comments on the machining qualities, UV resistance, and overall
strength
of
these would be greatly appreciated.
