Tank - 3 hours
Last night dad and I finally got back at the tank. We got the last rib installed. This is the inboard rib, so we squeezed the rivets instead of bucking them. We also installed the tank attach angle and reinforcement plate. Next time we will install all the plumbing fittings, flop tube, anti-hang-up bracket, a few other small parts, then the baffle. After that it will be time to leak test. Then the rest of the wing goes together quickly. Then it's on to control surfaces. Then I'm out of money and will be waiting until I can afford the fuselage... =D

Back at it - 4 hours
Hopefully the lull is over and I can start working on a regular basis again. I apparently missed an entry where I got a few small things done, and started countersinking the holes on the main spar:
Well, last night I finished countersinking the holes along the bottom side of the main spar, and deburred and primed all the holes on the bottom sides of the main ribs.
The initial plan for last night was to complete the tank, but I was out of popsicle sticks! These are a necessary tool when working with proseal, so I put off closing the tank for one more session. Instead, dad and I worked on prepping the leading edge for assembly. I deburred all the rivet holes in the ribs, then dimpled the holes and primed the ribs. I also installed the rivets on, deburred, dimpled, and primed the joint plate.
Then we deburred, dimpled and primed the leading edge skin. I don't remember the edge of the other one being so wavy after dimpling, but I am sure this will smooth out after riveting.
Here are some updated shots of the tank. All she needs is to have the rear baffle installed. The second shot shows the inboard bay of the tank, and all the stuff that goes in there (flop tube, anti-hang-up brackets for the flop tube, trap door, etc.)
