Trim tab assembly is complete. The Prosealed ribs need to cure for a few days before proceeding. Tomorrow I will cut the hinge and mount it to the elevator in preparation for the trim tab attachment. I figured out, only after I riveted the horn on bottom of the trim tab, that the rivet nearest the horn on the trim tab spar should be done before attaching the horn. There is no way to cleanly buck the rivet otherwise. The second trim tab went much smoother (as is the nature of the second time through any task) I was able to open the skin up far enough to back rivet all of the bottom spar. Faster and nicer sets.
Hinge attachment went smoothly with no drama. Now that I see the fit/finish of the trim tab to the elevator, It looks untidy. I will need to find a way to clean that area up, perhaps doing a little glass work. I have seen other mention the bending over of the tab close outs is not very attractive, and I have to agree.
I have the next week of work, so mutch might get done if I don't get distracted by other things.
