I had some spare epoxy left over from coating the centerboard. So I gave the rudder blade it's first coat. I have yet to drill out the pivot hole to final size and coat in epoxy. I'll likely use a 3/8" through bolt. Not for strength, but for larger surface area to pivot around and easier to epoxy coat inside hole. The pull up and drop down lines won't be under much stress so a small rope will be used. I'll also use a wing nut to tighten the blade up. (I had this on a previous boat and liked it) The end of the bolt will have a lock nut just to ensure that the wing nut never gets lost.
Too good to be painted in my opinion.
