Stainless pivot tubes

filleting the tubes prior to glassing them in place
close up of stainless shear pin tubes. I've used a couple of pieces of synthetic roofing material, some sheet foam and a little peel ply to help mold the epoxy/micro mixture in place. When cured, I'll remove the sheet material, rip off the peel ply and give it a final shaping before glassing the tubes in place.
When complete, cedar dowels will be inserted so that if the rudders should happen to strike something, the dowels will shear, allowing the rudder boxes to kick up instead of bending or breaking the rudder shaft.
