Joe,
Yes, Corsair had a stainless collar above the Delrin as well. That is
one of the reasons that I never changed it. There was one set screw
that I couldn't get to very easily and, of course, it wouldn't come out
with an allen wrench so I left it until we broke the boat. It still had
dried and crazed quite a bit. A quick shot of McLube now and then kept
it happy.

The stainless collar I have on the shaft above my bearing keeps sun
off the area right next to the shaft. If the hole gets too big it will
be from wear, not UV.

Neil,
Yeah, I knew Delrin wasn't the best. Considered UHMW, but the Delrin
was convenient.
Regardless of the disc, I see having a sleeve bearing set in the disc
that I can easily change as an advantage. Would be easier to swap the
bearing than to refabricate the disc with the 6 bolt holes and the
center hole each time.
As I said at the end of my document, maybe a non-metal sleeve bearing.
Just a "play" project for now.

Dennis,
I think your problem is accelerated by UV degradation. Delrin
isn't all that good in UV exposure. I would suggest using bearing
grade PEEK but that is a lot of overkill. You may gain some
advantage by making a sunbrella cover for it (or just replace it
every 7 years).
