Modify top swivel on CDI spinnaker furler

[flightlead404]

I have an older CDI spinnaker furler.

Well, it's less of a furler than an automatic backwrapping device. I curse it every time I use it. It could have been better designed by a boss eyed middle schooler.

I need to tear it apart to be sure, but I believe the big problem is the "designer" is relying on the slippery qualities of a Delrin or similar bushing to allow the torque transmitted by the torque cable to spin at the top. However with even a little tension on it the friction is high and it does not swivel correctly.

I plan to replace this Delrin bushing with a proper taper roller bearing and appropriately machined seat. I have access to a milling machine and small lathe at the local EAA chapter.

Has anyone done this or have any relevant advice on the topic?
