Bought a 3/4″ MDF panel at Home Depot. Leveled it out on the bench and shimmed the dead spaces with sheets of paper to create a flat surface.
Prepped the skins, spar, and trailing edge with isopropyl. Mixed up a small batch of fuel tank sealant and put a thin layer on each side of the trim tab ribs and set them in place. I used the 3M VHB tape on both sides of the trailing edge. Used clecos to align it with the bottom skin and set it in place. Then I clecoed the top skin in place along the spar and trailing edge. I peeled the paper from the VHB tape between the top of the trailing edge and the top skin removing clecos as I went to avoid tearing the paper. I replace the clecos to clamp the whole sandwich together while the tape sets up.
The sealant is ridiculously sticky and smells like ass.
I riveted the top skin and hinge to the spar.
All done!
Weighted down the skin with a board and some 2×4’s to ensure contact between the skins and the ribs until the sealant sets up. The spec sheet says there is a 6 hour cure time for the B 1/2 sealant I used.
