I'm going to have to look closer but, all I could really see was the fiberglass tube with an aluminum flange at the top and the rudder basically hangs by a pin from there. 2 1/2" thick teflon looking "washers" keep the pin off the aluminum and pretty much ride on each other to reduce friction. I was thinking of just adding an SS washer to try and distribute the point loads from the pin. I'm thinking a should just replace those 2 teflon looking washers as long as I have it apart. But, honestly, I think they would work just fine. I think the idea is just to keep thinks nice and slippery up at the top. Although, a nice tight fit would keep it from moving about. Maybe I should take some good measurements with a caliper and have something machined for the top and the bottom? It's obvious this rudder has been removed a number of times. I'm wondering whether or not it would get dropped every few years to add anti fouling between the hull and the rudder. So, maybe I get 1'-0" length of 3-5/8" delrin rod and have all those pieces fabricated at a machine shop? Then,slap it all back together? I keep thinking I should improve upon what is there just because I have it all apart.

Any decent machinist should be able to do it. The next one I have made will be from 1 inch or 2 pieces of 1/2 inch to increase the bearing surface. Dennis C.

I think Dennis C. and/or Joe D.B. scored some made from PEEK or some such...you can make them yourself from sheet stock or have a machine shop mill them out.
