Did some more work on the forward bottom skins tonight. (still trying to work on that weeknight work ethic…) I match-drilled all relevant holes between the skins and the gear crossmembers and intercostal ribs. Next I removed the skins and final-drilled all #30 holes, along with opening up a few holes for structural screw around the landing gear weldments. Finally, I deburred all the holes I’d just final drilled, and formed the edge of the main bottom skin where it will overlap the mid bottom skins.
Next up, I get to do some countersinking and dimpling, plus I still need to finish the edges of a couple skins. Then it’ll be time for some riveting!
