Tailcone Aft Bulkhead is Complete




Spent the day completing the aft bulkhead. My hands are sore, there are a whole lot of rivets that one has to squeeze. Now know why some buy the pneumatic riveter. Also, had to use the Mil-Spec for riveting, there a number of the rivets that appear short per the Avery gauge but are OK PER the mil-spec.

No real problems with the plans, except, Step 6 on Page 10-04 tells you to final drill the eight 3/16" holes. As F-1211A and F-1211B are disassembled at this time, I think the plans should tell one to final drill the 3/16" holes in both F-1211A and F-1211B.

Pay attention to the rivet call-out on Figure 2, Page 10-04. Lot is going on here.

Recalled a post on VAF, after replacing the die on the Avery pneumatic squeezer with the 3/32" head, the CCR-264SS-3-2 sure sounds different when they are pulled!!!

Did not have a problem reaching the rivets with the normal and the 3" yoke. There was one rivet on the tail skid bracket where I had to remove the die, insert the squeezer, re-insert the die, then squeeze it. To remove I removed the yoke from the squeezer by pulling the pins.

Completed the day by enlarging the hole for the SB437-4 bushing with a Uni-Bit to 7/16", then inserted the bushing. Another VAF post plans issue!

Will fit this aft bulkhead to the HS on Thursday, then can store the HS in the spare bedroom.

Time - 6 hours
