Prepared to rivet the F-712 bulkhead to the F-779 skin. First dimpled the 712 for the keeper rivets and then countersunk the WD 409 for the dimples. I misread the plans and drilled these holes to #30, so I'm stepping the keepers up to -4 rivets.
Began with the squeezer on teh aft 712 rivets and set those with no problem. Alternated with the gun and bucking bar to set rivets on the forward side of the bulkhead as well.
