Ever have one of those days where you think you'll have a few hours to spend on the plane? And then all kinds of things crop up, chipping away at the clock all day?
Had a few minutes, and since I'm getting pretty close now, I wanted to up-drill the forward fuselage side skins before disassembly for debur and riveting.
Updrilled all holes from #40 to #30, then to #20. Did not drill the upper line of holes in the pic, as these will be used during fitment of the upper panel skin much later.
