Oops, those custom hinge brackets to mount on the cross-beam turned out to place the hinge pin a couple of inches too far aft. So that’s two very strong but very useless parts for the bin. Took a new approach today tucking the hinge up under the net lashing tube, and building it all in place. The green piece is the G10 hinge tube, held in place by thick, fiberous epoxy putty.

The wood piece is a hardwood backing plate to help carry the motor’s force in to the beam. This new piece is adjoining the existing hardwood block that is the beam-to-hull anti compression pad.
Had to devise our own laminate schedule, so for the permanent record the hinge tube is held to the beam with two layers of 12oz uni glass, two layers of 12oz bidirectional and one layer of 45/45 double bias 17oz. All five layers wrap 48 inches long, reaching well out on the the beam fairing piece both top and bottom. Seems really comprehensive to me, but if any experienced builders reading this think otherwise, please holler. Thanks
