Forward fuselage countersinking, fuel pump shelf and primer

I continued by machine-countersinking the center section bulkhead to accept the skin dimples:

I also took advantage of not yet having the bottom skin on, in order to more easily attach and match-drill angles that make a shelf for the EFII install. I'm roughly following the instructions from the Aircraft Specialty hose kit, and may get the kit from them.

We had done primer on the skins earlier in the month:

This weekend we then did another large batch of primer, to get all the parts that need to go on the skin, before the skin is attached to the forward ribs and firewall bulkhead:

Next will be a lot of dimpling and riveting of those parts.

Time lapse:

Total forward fuselage bulkheads, ribs and bottom skin rivets: 0
Total forward fuselage bulkheads, ribs and bottom skin time: 70.2h
