Next in the line up of bulkheads was the 706. This was a very flimsy piece to start out with. Many little intricate pieces go together here with many specifics so read the plans carefully. Especially when you got to rivet them together. I also deburred, fluted, prepped and primed the other bulkheads for later on. I wash the scuffed metal in a bath of dawn before rinsing the crap out of them drying and wiping with naphtha. The small angle at the top gets countersunk for that front plates dimples.
