It has been too cold to paint, and I haven’t been spending many hours in the hangar. Today I finished cleaning up the tiedown rings, and started drilling the door skins and frames to final size. They were all drilled to #40, but I’m planning to use 1/8″ rivets to hold the skins on the frames, so I started drilling them out to #30. Today I did the right front top and bottom, lower left door, and started on the rear cargo door. The larger holes made it much easier to shake out the little chips of steel that were rattling around in there.
