Try this. Take a 5/8" square length of spruce, Fit a piece of piano hinge to it . Predrill the piano hinge and spruce every second piano hinge loop.Rough sand the under side of the piano hinge and then wash it in acetone and hang up to dry.Use long 3/4 " aluminum pop rivets. Place them in acetone and then dry them. Mix up some epoxy and cover the wood including the holes. Cover the loops of the piano hinge with vinyl or masking tape to keep the hinge clear of epoxy. Dip each rivet in epoxy and insert them in the holes. Pull each rivet in turn. Lay two layers of fibreglass over the top of the riveted area .This will be for the connection to the fibreglass couling.Let it cure for 24 hours. You will destroy the hinge in trying to tear it apart. The othe side of the hinge can go onto the stainless steel fire wall or onto the wooden structure using the same epoxy/pop rivet treatment followed by glass cloth over the riveted area onto the wood of the fuselage. I used 2" hinge on the top and two vertical sides to hold on the top couling.The bottom half is similarly fastened to the top by two hinges, fore and aft on each side. In all cases the pops are fibreglassed in as part of the "meat" in the sandwich. All comments both + and - are greatfully received. Harold Woods Orillia,ON.Can. haroldwo...@rogers.com
