Elevator Trim Tab

Well, I spent a solid 2.5 hours in the garage today working on the left elevator trim tab.

First step, let’s find all the pieces (like the two halves of the trim tab horn) and get them clecoed to the rest of the structure.

The 1/8″ cleco is making sure the two halves are aligned during matchdrilling.

Then, I decided to forego the folding of the tab halves, instead going with a fabricated riblet. (I made two of them, one for each side of the tab.)

Cleverly, I offset the rear attach holes so I would have less trouble riveting.

Then, I drilled, disassembled, deburred, dimpled, scuffed, and primed the skeleton and interior of the tab skin.

Of course, I got lazy about pictures, so here’s a finished shot of the bottom of the trim tab.

The rivet gun got away from my on two rivets in the middle of the tab. I may choose to replace this all later, but for now, it’s fine.

Because I’m lucky, I was able to finish the top half of the tab with no mistakes.

Finished! 

Here’s another shot of the bottom half.

Doesn’t look to bad here.

Of course, I had to stick the hinge pin in and see how it looked.

It looked DAMN BEAUTIFUL.

Anyway, when I can see the future and know I won’t post tonight’s work for a few days, I sometimes take a picture of my time-keeper. 2.5 hours tonight.

I always use the right side to keep time, I have no idea what the left side was timing.

2.5 hours. 42 rivets.

I'm too lazy to fill this out. If you are actually reading this, send me a message, and I'll spend some effort on it.
