I have an old CDI furler
(circa early 80's) that doesn't have bearings. I've disassembled the whole thing to inspect, clean, and lubricate it.
There's a plastic wheel
fixed to the toggle right under the turnbuckle that allows the drum to rotate. The drum wraps this wheel
. I was going to use a teflon-based spray to lubricate the assembly, but I'm not sure that stuff will last more than a few weeks (although not directly exposed, the wheel can receive some water
and dust). It's not easy to lubricate the part without disassembling the drum.
What do people use to lubricate this type of furler
We do experience a fair amount of friction when unfurling the sail, but now that I know how it works I'm suspecting that the foil may be the culprit for most of the friction.
