Project: TerryS     -     Entry

Feb 26, 2020 5 L/H elevator Category: Empennage
Match drilled, dimpled/countersunk, primed faying surfaces, folded trim tab closeout etc. Everything came out good.

Ran into a situation on the 4 holes upper & lower in the trim spar that are outbd of the closeout fold. I don't really see how you could match drill them before doing "the big fold" so I didn't, but then there wasn't a way to get either a squeezer or c-frame on them to dimple afterward without unbending the skin.

I thought about it for a while and ended up drilling a #10 hole in the oak wedge that I had made for bending the tabs so that it would hold a female #3 dimple die. I was able to slide it into the skin without unbending anything, put the male side in a cheap 7/32" socket and then smacked it with a BFH to make the dimples. came out really nice.

I'm pretty happy with how the trim closeout flaps came out as well. The secret is to tape the entire hardwood wedge with really sticky double sided carpet tape, then clamp it to the table & tape all of the edges of the whole elevator to the table as well so that nothing can move at all.
