'I battle gravity'
Okay, I'm clear on the principle of building a motor mount with fins on the bench outside the body tube. I even understand the reason for doing so and how to install the completed structure inside the body tube.
A rocket kit I'm working on has three centering rings. I see no problem in applying the epoxy/glue inside the body tube for the uppermost centering ring and of course the gluing the rearmost centering ring in place is a simple matter as well.
Question: How do I get the epoxy/glue in place for the middle centering ring? Should I wait until the motor mount is installed and then add the fins (with no internal fillets on the motor tube) as I have done before? Sometimes I drilled holes in the body tube and injected epoxy fillets...my Mad Cow Frenzy comes to mind.
The kit is an 3" upscale Cherokee-H by T. VanderBurn and the scaled up Cherokee fins are rather large as you can imagine.
Seems weird building a rocket kit from a kid/guy I remember from when he was about 8 years old...I used to fly AMA Free Flight airplanes with his dad.
