I think I can fabricate the missing and broken parts - I hope those of you with roller furler
experience might add some guidance... The manufacturer supplied a user manual, but few other mechanical details.
The drum is cast aluminum
in two halves. At the base, it's clamped to the bottom of the stay turnbuckle. The stationary part is Delrin, about 4 inches diameter and runs inside a groove in the aluminum
drum to form the bearing. Apparently this is unlubricated. I am not a bearing expert by any means, but Delrin / aluminum ? seems like a lot of friction to me ... should I install a grease fitting?
The foils are stacked over the 1/4" forestay and coupled together with delrin inserts of unknown design. The whole shebang rotates around the stay and has an integral steel halyard.
If you've used anything similar, I'm all ears.
