Drilled brackets to the square tubes on the firewall and bottom skin. Unclecoed the firewall and bottom skin to allow easy access to drill the forward spar box to the side angles from the aft side using the 12" drill bit. Drilled these, then disassembled the rest of the forward fuselage. Started deburring. Got through about half of the parts. Need to finish that, then work out what dimpling/countersinking still must be done for the spar box, then reassemble.
