There is that nervous pressure that the upcoming launch could not go well. The specific issue is a first time user (me) using shear pins twice for a dual deployment flight. A new Wildman Jr is about to go up on a mild load to test systems and it is not clear how much Oomph is required to separate the 2.6 inch x 18 inch booster section and payload bay with (currently) one 2/56 shear pin.
The question is, how much black powder will it take to assure the shear pin will break free?
Please feel free to point toward existing information and formulas for this - I just couldn't find them.
