I didn’t see one on the main spar, just the rear spar. Assuming these were marked at the factory when they assembled the wing to keep things straight. Still nice and clear, easy to read.

The garage warmed up enough to work in the fuel attachment points and install the drain grommets and dollies.

I stuck my snake camera into the tank and it’s surprisingly clean inside. Still , I will wash it out.

Cleaning the exterior of the port fuel tank. This small project took all weekend from the first photo to the last. I did do a few other things in between.

Bottom side.

It took about an hour to lay down the tape and install all the screws and washers on the top of the wing.

Chalk lines to keep your fabric and tapes straight and the laser was for checking the leading edge for bumps and dents. Other than the Rivet and screw heads, the leading edge looked good.

Getting ready to install the wing tank and finish up the tapes and the inspection covers. No fabric goes over the wing tank, just around the edges.

Lot of man hours in a little aileron. This took all weekend and I’m not finished.
