Im messing around with a carboard mail tube trying to get it right, i think ive got it but since ive never used shear pins before, im not sure if the ejection force will pull out this tiny washer. It fits m2 screws. (It wont be this close to the edge, just practicing)
I tried different ways and what ive landed on is;
1-ca both sides of the tube. (Not sure this even helps)
2-drill 1/16th hole
3-sand around the hole on the inside so the washer lies flush
4-tap the hole
5-dab epoxy over the counter sunk hole
6-place washer over it and thread the nylon m2 shear pin, wiping away excess and ensuring the washer is flush
7-let it dry, back out the screw.
8-sand any exess.
Ive seen someone on here do it similar with a larger piece of quarter size thin sheet metal, then thin layer of fiberglass over the metal.
This will be for my L2 dual deploy flight on a 5.5" LOC big nuke. I feel like its got to be a little better than trusting the threaded cardboard to shear the pin... I'm just asking for thoughts on it
