Some of these photos are of the Centerboard, some of the Rudder. All the concepts are the same.With the oversized holes drilled and filled with thickened epoxy, I used a scraper to level the epoxy with the surface of the foil.I then used my drill press to drill out the center hole.This produces a lot of cool looking shavings. You are striving for a perfectly centered hole…I’m close. The center hole will take a bushing, the top hole will accept a 3/16″ line for the rudder downhaul.
I pushed in two centerboard bushings to determine length. I then used a metal file to roughly determine where to cut the bushing. Due to the thickness of the foils, it takes two bushing to create the length needed. The centerboard bushing being cut with a hacksaw. The bronze cuts quite easily. I scored the bushings for better epoxy adhesion.Bushing installed in the centerboard.I added some thickened epoxy around the bushing to seal the outermost area.Bushing filed flat. I’ll re-coat this centerboard one last time with graphite epoxy. This side of the centerboard is now ready for it’s final two coats of graphite epoxy.
Fun stuff here…now ready to bright finish the rudder.
