Cut 2x4 on side to get 10degree cut that fit inside and over trim tab skin. Bent tabs down starting with block of wood and hitting with hammer, Top tab, one with pre drilled holes, had to be started, then bend with wide skin bending pliers. Needed to hold under tab flush with wood block to continue bend. Finished with rivet gun and mushroom head to get a smooth even bend with good corners. DONT dill end holes until spar and ribs are in place, or else it could be too tight or loose.
