Primed parts and started assembly

Primed all of the parts.

Dimpled the bulkhead and side channels.

Riveted the doubles to the bulkhead.

Riveted the side channels and doublers to the bulkhead. Unfortunately I didn’t see the note in the instructions indicating that the manufactured heads should be on the aft side until after I had driven all the rivets. So I got to drill them all out and do them again. Yay.

All’s well that ends well.
