I finished drilling the holes for the rack stack tray support.
I then proceeded to drill holes to mount three adel clamps on the three ribs of the upper fuselage assembly.
I painted all the parts and after the paint dried, installed the tray and the adel clamps.
It appears that my flywheel on the compressor is out of balance. Not only did the steel key pin get pulverized, so did part of the spindle. I'm now without a compressor for the moment.
