Tonight I clecoed the forward and aft roll bar assemblies together using the two straps. The straps are lengths of flat aluminum, which require some bending to help them align with the curves of the roll bar. I wasn’t able to get them to bend very well, but I managed to get enough bend to make assembly easy.
I started the final drilling process, but need to take it all apart, debur, then reassemble and continue. I’m doing it that way to prevent too much build up of shavings that might cause a misalignment issue.
