Rich, I know what friction fit is, and I do have a problem with the lower section. It was very loose. What I did was built up the coupler/EBAY with epoxy. I think I will have to add one more layer. As for testing that friction fit, just how do you do that. I know that the lower part of the rocket that fits in with the EBAY/upper body slides out very easy. The nose cone/upper body joint is fairly stiff. Kind of makes a popping sound when I separate them. It's actually fairly difficult to pull them apart with my arthritic hands.
Not sure what masking tape is meant in your reply. Do you mean to put small tabs of masking tape on the outside at the coupling joints?
From what you are saying, shear pins are really for larger rockets, in particular, the fiberglass/composite types.
