I started the day by drilling the bottom skin to the Lower longerons to #3 size. Still fiddling with the fairlead assemblies. With the vertical channels rivetted in, it will be a little problem. I made a template for the four drill holes on each fairlead part.I found one rivet on the fuselage side which didn't sit flat so I decided to drill it out. The drill bit broke off inside the rivet. How to get it out? I'll sleep on it. That seems to work well.The web and the other piece came from the factory. The holes don't line up. I'll make another piece tomorrow from 3/16 aluminum
