Fabbing the right aileron
I have been working on the right aileron for the past several days. I have gotten the gas tank done and have counter-sunk the screw heads. I had to pull the tank back off since I did not like the fit of the tank skin to the top skin. There were several spots that stuck up a little. I have since massaged those areas and will be fitting the tank back onto the wing, hopefully, for the last time. I have also riveted the stiffeners to the aileron skin and have to make a jig before I can drill the skeleton to the skin. I hope to have all this done here in the next day or two and then I can start the process of mounting it to the wing with the hinge brackets. After that I can fit all of the gap seals and brackets and then mount the flap. I can't wait until I am done making all of the control surfaces.

Gas Tank Finished!!!!
I have finally completed all the pro-seal needed to complete the gas tank. I have to mount it back on the wing and counter-sink the upper row of screws. I am sure glad that is all done and now I can get moving again with the build process. I have been working on the right aileron. The stiffeners have all been drilled to the skin and now I need to etch, alodine and prime tomorrow. Then I will rivet the stiffeners to the skin and get going on drilling the skeleton to the skin. I have modified these ailerons by switching the end ribs around. I mounted them flush, so the flanges point toward the inside of the ailerons. I will have to use pop-rivets to rivet the end but that is ok. I want the edges flush for looks and maybe to gain a little more speed.

Tank baffle is installed
I have gotten the tank back baffle plate installed over the last few days. I got all the ribs installed last week. I have to wait a week or so to let the pro-seal set up before I can install the rest of the components in the gas tank like the sending unit, back access covers and drain. I will then put it back on the wing so I can countersink the front line of screws and final fit it to the wing. It fit real nice in the jigging process but things tend to move a bit in aseembly stage, especially with pro-seal. Parts can slide a little when you squeeze the rivets. I have started on the right aileron for now and will get that assembled so I can mount it on the wing and close up the bottom skins.

Sealing tank ribs
I have been working on riveting and sealing in gas tank ribs. It's a long process to get the rib gooped up them stuck in position (without getting sealant everywhere). Then I buck each rivet twice, cleaning off the bar and gun each time. Once all the rivets are bucked I squeeze a little out on each rivet head and swirl it around to seal in the rivet from the inside. Hopefully this way I will have double sealing. After all the heads are sealed, I then seal along the rib and skin making a nice fillet with my finger. Each rib takes about two hours from start to clean up. Can't wait until this sealing is done.
