Today I started off by using the air squeezer to dimple the ribs and rear spar of the left wing bottom & the right wing top. I still have to dimple each wing's opposite sides. I also used the machine countersink to countersink all of the AN-426 small rivet holes on same sides as stated above. I used a test 426 dimpled template to ensure the right depth on the countersunk holes. I then hung the left wing bottom skins with a few clecos just to kinda test fit it...and they look like a nice fit! Afterwards, I blew off all the FOD aluminum shavings from the spar and cleaned the shop up.
Next session I will flip the wing skeletons and dimple and countersink the opposite sides of the. I will also "scarf" the left wing bottom skins a little better.
