Hello, I'm in the process of designing an L1 rocket using 98mm*48in Blue Tube. I've designed a mechanical motor retention system for its ejection charge, but I'm also adhering my fins to both the motor mount tube and the body tube on the outside if possible. (is it somewhat reasonably possible to cut slits for fins into blue tube?)
Assuming yes, could I use either 4 or 8 bolts radially through the blue tube into the mount to hold the motor retainer for flight? This is somewhat structural, so I don't want to tear the bolts and motor out of the tubing at ejection. Basically, would the blue tube tear at the bolts or is it capable of withstanding a bit of force in this case.
I know this can be mathematically worked out for well-understood materials, but I doubt I could find data for blue tube like I could for aluminum or steel, so I'm going for knowledge by experience here.
Thanks
