Matt,

Another step that you could add to really lock the hinges in is to drill a hole through the surface perpendicular to your hinge line. about 3/4 of the depth of your hinge, then fill with aeropoxy from that hole. until the aeropoxy oozes out around the hinge at the hinge line. After it dries you will have to rip a chunk out of the wing or surface for it to pull out, as it forms a Tee with the shaft of the Tee being the hinge. I have also started using the BVM CF hinges for all of my hidden hinge lines they work very well and a very strong.

Good tutorial!
