    While the flaps seemed fairly straight forward, there were a few new and interesting tidbits in the plans that haven't come up in previous parts. First was the use of duck-bill pliers to eliminate "pucker" in the ribs. I didn't actually own any duck-bill pliers by that name, but had a small pair of flat (non-grooved) surface pliers that I put some tape over to not damage the aluminum and straightened out the bend as best I could. It was pretty subtle to start with, but it came out slightly more flush so I suppose mission accomplished.

    And "pucker removed"!

    Next were the inboard leading edges that required doublers and a large nutplate. Pics still need to be deburred, but everything went together nicely.
