A plastic coffee can lid with a hole in the middle would work. FYI - you all do want to pay attention to these bearings. If they get sloppy a tremendous amount of strain gets transmitted to the lower parts of the assembly instead of the bearing.

I'll figure something out. I have a rubber washer on top of my hydraulic backstay adjuster to protect the top seal. Dennis C.

If the hole gets too big it will be from wear, not UV.

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 C.

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). _______________________________________________ Thanks everyone for supporting this list with your contributions.
