I decided since I had a second trim tab skin and I messed up the hinge line on the tab, I thought I might as well build another tab. I bent the tabs just fine, but had to make a mistake on the hinge. The hinge was too close inboard and was rubbing when open and closing, so, not acceptable!
So I ordered an AN257-P2X18 hinge, E-717, E-718, and the E-607PP.
