I convinced my wife to come help me install the antenna mounts. In image one she is drilling the doubler to the floor. Collectively we drilled, deburred and dimpled the doubler and bottom skin, then riveted and installed the antenna.
We also riveted the two comm antenna doublers in place, but I have to wait until the wings are on to install the antennas. They will conflict with installing the wing bolts. Julie also installed a bolt on the engine for the baffles. This bolt is behind the oil filler tube and I could not get my hands in there to get the bolt started.
We also came up with a plan for sizing, cutting and installing the baffling material. Julie is taking that on so I can work on other things.
