A lot of older furlers are obsolete because the companies have changed the design and no longer support the older stuff. There are also a lot of different foil types sizes etc. So to get the right drum the design is critical. Some will only work with a particular foil pattern. CDI
for example went from rigid piece type foil to a plastic flexfoil and the list goes on. I had two CDIs one 49 ft and the other 56 ft They had the same foil pattern but different head
and drum sets. Had the same problem as you. Things were getting brittle and breaking. Had to replace the two furlers. Installed Alado from Brazil
. Drum, Drum housing, head
assembly heavy duty. Cast aluminum
and uses the inside Halyard
(which I wanted). Easy to install.
