I am building my 2nd ARCAS (the first one was over 15 years ago), and when ordering stuff I decided to throw in a bag of 2-56 nylon screw shear pins to experiment with. However, I did not use shear pins of any kind on my first ARCAS, and I'm not sure exactly how to make use of them! So a few questions from a mid-power almost-newbie... If I use 2 pins to retain my nosecone (rocket is being converted to dual-deployment) until the proper time, how does one go about removing the sheared-off portion of the screws after deployment??? Since the main body tubes are a paper fiber, what do people use to reinforce the holes in the body so they don't elongate with use? Thin CA adhesive? That's all for the moment... I'm sure I'll come up with more later! Thanks!
