Removed the F807, F808, F809 bulkheads and the F869 gussets. Removed F882 canopy rail receptacle, and the F807D harness fairleads. Deburred everything. Scuffed up the bulkheads, gussets, canopy receptacle,fairleads and shoulder anchors. Then used the pneumatic squeezer to dimple all of the #41 and the #30 holes. Had to bend the bottom flange on the canopy receptacle in order to dimple the holes. After this part is riveted, will bend it back. Countersunk the F808 bulkhead for NAS rivets to attach a couple of nutplates. Machine countersunk the shoulder anchors—had to freehand c/s the two end holes where I had filed a step down to fit under the tabs of the bulkhead. Deburred all of the holes in the aft top skin-there’s a bunch of them!
