In this session, I began work on the fuel tanks and started by straightening and fluting the fuel tank ribs. These ribs come supplied with a lot of distortion from the manufacturing process so I had to use the fluting pliers along their flanges to allow them to sit flat. The flanges also have to be bent to ensure they are 90 degrees from their webbing areas. Then I started marking the cuts I would need to make for the various stiffeners, which are all supplied in long pieces of angle stock that only have guide holes punched in them. I did have time to cut out and smooth some of these ribs on the band saw, but there are still a lot more to go. What's next? Finish marking and cutting these stiffeners, then prepare more raw tank parts.
