Re: Bristol 32 rudder pivots
Well here is the deal with the lower rudder pivot on a Bristol 32.
At least on a 1975 vintage, hull 165, there is NO bronze shoe. There is a bushing set in the fiberglass that looks like it is a shoe, that supports the bottom of the rudder. The bushing was fine. There is a hole in the bottom of that fiberglass and if you can either look up into the hole or use a mirror, you will see the end of the lower shaft. That shaft is held in place by a transverse bronze bolt with a flat head that is found by grinding away some of the fiberglass. That trasnverse bolts has a nut on the other side also found by grinding away some fiberglass. To remove the pin, support the rudder, remove the trasnsverse bolt and the shaft will slide out down through the hole in the bottom of the fiberglass "shoe". It can't be very long as my "shoe" wasn't that far off the ground. Perhaps a bit more than a foot, but not much.
My pin was flaking away according to the yard. I didn't see it. A new shaft was made with the appropriate hole for the transverse bolt and simply slid into place. Oddly the vertical shaft was tapped 1/4 20 thread on the end to accept a bolt perhaps. I don't know why the threads are there but those threads were made in the new shaft by the machine shop in the event I ever find out. The cost for the pin was less than $100.00.
It was about a $1000.00 job in total give or take. No wobble now and presumably good for another 35 years.
