Tanks: deburr & dimple

Hours: 5.4 | Posted in Fuel Tanks

Not much to show visually today, but spent several hours on tank prep.  Installed the nutplates on the spar for the inboard tank attach bolts (after spot-priming the countersinks).  Starting with the right tank, disassembled the pieces and deburred all holes & edges.  Dimpled the skin with the DRDT and the ribs with the squeezer.  Moving on to the left tank, got about 1/3 of the way through the skin deburring before the battery in the deburring screwdriver went flat, and the temperature began dropping more rapidly…time to call it a night.

Proseal, landing lights, and a grab bag of hardware (rivets, bushings, etc) ordered from Van’s last night.
