I reached a point where I needed to have the roll bar assembly riveted in before I could continue with the canopy frame, so today I assembled the roll bar.
First I clecoed the roll bar in place, hit it with a rubber mallet to make sure it was seated on the bases and then match drilled the required holes into the bases. Then I removed the assembly and deburred and cleaned up all the drill chips. Then I assembled it again and did the riveting.
The roll bar is pull riveted to the bases because there is no access to the inside. I used my pneumatic pull riveter for these. By the time I finished riveting the bases I had used all the rivets provided in the kit. They cut the count close- no extra opps rivets in this kit.
Here I've attached the bushing and the doublers with pull rivets.
The roll bar brace gets attached with some hefty pull rivets on the top.
The back of the roll bar brace is riveted to the fuselage using solid rivets. A couple of these were a pain to reach behind the bulkhead...
Flush rivets are used to attach the brace to the top skin.
I finished up today by riveting in the skin diagonal longerons.
