The guy that I made those for sold the boat but I'll see if he can get some photos of them. I used 1/2" conduit for the pivots. I welded "ears" on the conduit before forming the fiberglass to keep them from spinning in the rudder. The rudders were formed from Styrofoam then fiber glassed. I do have the photos around somewhere on a disk, I had looked for them a while back with no luck but I'll keep looking.
