Keel repairs
Posted: Fri Jan 13, 2012 10:30 am
Following my earlier post, I finally solved my keel problem by reaming out the old bush and buying a length of stainless threaded rod to go through it and a bronze nut to fit.
I then cut the nut on two opposite sides so that it would fit under the old bush.
Next I ground one end of the rod to take the winch fitting and the other end to take a stop washer which I had welded on.
Finally I put the nut on the rod and threaded the rod up through the old bush and through the keel case and fitted the winch mechanism.
The length of the rod is critical but it can be done and it works.
The beauty of the system is that if you touch ground the keel lifts and the friction is taken up by the old bush which being bronze shouldn't damage the rod.
I am now wondering whether I could put the rod and nut in a housing on top of the keel box with the nut wired to the keel. In that way I could keep the mechanism greased.
