Finished countersinking the #8 holes on the main spar. Drilled and countersinked holes for inspection plate platenuts. Riveted platnuts, but did not contersink screw hole, waiting for proper dimple die to dimple plates for close fit.
Started tie down bracket fabrication, but had to stop when I broke the tap due to not drilling out the hole to the correct tap size first.
Laid out rear spar components for assembly in the morning.
