Preparing the Trim Tab Access doubler and brace - all etched, primed, dimpled and ready to rivet.
Riveting in the nutplates was a little fiddly but got it done with no issues...
There's something about getting the rivets flush and consistent.
Riveting the Trim Tab Pushrod is a little different in this case as both outside pieces (E-1401A-L & -R) are countersink and riveted together - I should've practised this on some scrap parts first. As it turned out, this version of the Trim Tab Pushrod became scrap anyway.
The first countersunk hole was too large...the second, much better. The below photo shows I've (for some reason) countersunk the incorrect sides of E-1401A-L & -R. I still riveted them together to see which rivet size would suit better as the one listed in the plans (AN426AD3-3.5) seemed too small so I went up to an AD3-4.5 which looked much better.
The flush side of the rivets looked really nice and was hard to tell it was rivet if you ran your finger across the top - it was very smooth.
I ended up using this as a test-piece mainly to find the right length of rivet to fill the shop-head side up as much as possible. As you can see below, the one left was the recommended size but didn't come close to filling up the space. I upped the rivet length from 3.5 to 4 which was the one on the right.
and another shot of the nice flush AN426AD3-4 rivets...
Rocket dropped past to grab a beer so I set him going on dimpling the Elevator Trim Tab parts instead...
He seems happy with his work...
Wasn't happy with this rivet so....
I drilled it out and reset it...
Unfortunately I didn't notice one of the holes wasn't dimpled until I was a couple of holes away riveting. I had to drill about 4 rivets out to give me enough give in the skin to get the dimpler in there to fix it up.
