Hellraiser.... The Abbreviated Build Thread.
Airframes, PT Deux: lower/fin can connection, av-bay mounting and switch holes.

I have a 2000 Subaru. component size is dictated by trunk space. Therefore, to permanently attach the lower airframe to the fin can, creating a 60" tube is simply not feasible.

During mock-up, holes are drilled in the upper airframe into the coupler. Threaded inserts are epoxied into the coupler. 8 #10 screws in a staggered pattern bolt the lower airframe to the fin can.

The top two centering rings are mounted in the coupler, with the coupler insert installed. The threaded inserts are visible up near the fore CR.

Marking switch location for the av-bay on the upper AF. This particular tube was going to be used on something else, which is why the spirals are already filled. It added a little bit of weight, so that's why it's serving as the uppermost airframe section.

And the holes drilled. The one looks a little rough, I admit. I'll get her cleaned up by flight time. The av-bay is attached to the upper AF by 4 #10 screws and threaded inserts, similar to the lower AF/fin can. This will let me transport the rocket in Subaru-sized chunks, and assemble at the field without too much trouble.

Next: layup.
