Question: Are there gudgeon and pintle rudders on boats over 40 foot that displace more than 28,000 pounds?
After dissassembling the rudder and lower rudder shaft, there is no rudder bearing. It's just a large black rubber bushing. There is no lower bearing whatseover. The steel
surface of the rudder post was moderately corroded, around 1/64th of an inch or so of scale. Very Minor. Corrosion
control on the steel surface was just a single
layer of enamel, which was entirely worn away. The rust particles were compressed into all of the 8 vee grooves of the rubber bushing which caused the tight rudder.
Anywho. The lower rudder shaft is going into the lathe tonight, to get cut down 1/32 or so, to be sized back up with epoxy
resin to fit back into the bushing. There isn't enough clearance in the shoe to fit bearings. Thus an extra thick coat of epoxy
with West 423 carbon powder, milled back to spefication, for the wearing surface of the lower rudder post, then back into place.
