I am still wrestling with my mutilated rudder on my ex-RN FMD of 1953. All I have is the stock shaft-("high tensile copper alloy", which I presume to mean bronze?). . .previous owner sliced off the blade -( Twit). If I make up a replacement in 316 stainless , will the bi metal effect damage the gunmetal gland or any bearing surfaces in there?
I could not access the rudder builder site you recommended already. Thanks. . .Erik
