3/23/2009 Tank - 3 hours This past weekend I was able to get a few hours in on the tank. The first thing I did was disassemble the tank so that I could cleco on the stiffeners for match drilling. This also allowed me to cleco the z-bracket on from the inside, so that I could mount the entire tank to the wing. It took about an hour to disassemble and reassemble the tank. I match drilled the stiffeners, then bolted the tank to the wing so that I could match drill the tank skin to leading edge joint plate holes.
After that I machine countersunk the line of holes on the tank skin where the rear baffle attaches. This wore my elbow out!
Finally, I disassembled the tank for deburring and started fabricating my tank attach angle. My bandsaw is junk and won't cut 3/16" aluminum angle, so I had to make the rough cuts with my cutoff wheel / die grinder. That took forever. I called it a day.
