Wing Fuel Tank 18-2-1 to 18-5-2
Continuing on with the fuel tanks, I worked on separating the stiffeners. Due to their length, these were easiest to separate using shears. The tabs were then removed on the disc sander. I also cut and kept two vent clips that had been attached to the ends of the pre-formed stiffener angles. Separating the skin stiffeners using shears Shears tend to bend the cut edge slightly, especially on the first cut. I found it better to first cut on the side with the widely spaced notches (where the stiffener end angles will eventually reside), as the bent edge would be trimmed away. The end angles were then marked for cutting with the band saw. Cuts are made relative to notches in the aluminum angle. I drew lines to help guide a straight cut. Once the 28 stiffeners were cut to size, final deburring of these and 2 vent clips was done using the deburring wheel. I also reamed all the holes with a #40 reamer. Stiffeners and vent clips deburred and ready for test fitting to skin Next I straighte...
