2 hrs. finishing the fabrication and installation of the transponder/ADS-B blade antenna backing plate.

Riveted in place and holes drilled.  The center hole for the BNC connector is not yet final size (9/16") since I don't have a drill bit that big (I think).  Ended up not using the lower layer of the backing plate since it moved on me.  I'll just use some washers to bridge that space.  I may also end up enlarging the mounting holes slightly so that I can adjust the angle of the blade if I find that it's not perfectly lined up (once it's on the gear I'll measure the hole positions relative to the rivets on the outside).
