First mistake

I made my second part a trim tab that goes on the every back of the plane.  Well I measured once before I made a 90* bend opps!!! I straightened the part out and bent it again in the correct location. I did it mostly for practice because I scraped this piece and made a new one.  It's hard to see in the photo but there is a wave in the top of the trim tab. Plus when you bend a piece of metal multiple time it becomes weaker.

Here's the trim tab redo with the piano hinge clecoed on.  A cleco is a temporary fastener which will be replaced by a rivet. I remade that damn piano hinge three times. It was a pain getting the holes to lineup all in a row.
