[Rhodes22-list] Furling foil

[Mike Riter]

I had the same piece break on my furler and thought it would be easy to get
a new one machined at a shop. Because of its odd shape along with the
groove, it proved to be very difficult for the machinist to replicate.
Ultimately he had to come by my shop and take  a bunch of
detailed measurements on the inside of the tube to get the piece to fit
correctly. It was a pain and took a couple weeks to complete. I had asked
him to make it out of more rigid material and he said that wasn't a good
idea as the part needed to flex a bit. He did make it 1" longer on both
ends than the original. It's been a year now with no problems.

Getting the cable routed back through it was pretty straightforward. I
unscrewed the two part block at the top and was able to fit the cable end
through the hole in the center of the new part.

I'm guessing that as hard as it was to machine, that the maker of the
original furler tube had the part injection molded.
