More work on bulkheads

Modified the bottom of the 1408 bulkhead.

Deburred and dimpled all the 1407 and 1408 bulkhead parts.

Separated, deburred, and dimpled the bell crank ribs.

I realized when I went to drill the battery angles that I somehow modified the wrong one. I could swear that I marked these parts carefully before I separated them but it appears I switched the A and B markings. I don’t think this will be a problem though. I just needed to modify the correct one. The modification to the wrong one is not consequential.

Once I fixed that, I drilled and countersunk all the nut plate holes and match drilled the angles to the bell crank ribs. I deburred and dimpled the 1406 bulkhead as well.

I think next weekend I’m going to have two solid days of scuffing and priming all these parts.
