I just stumbled across this old video and I though it might tickle you guys.
On an archery forum back in 2013 someone asked if spine was important when sourcing material for crossbow bolts.
I said no, as there is no sideways force to flex the bolt.
Some know-it-all bawled me out for giving "dangerous advice" and said a bolt could buckle under the force.
So, I said I reckoned I could make a bolt out of paper that would shoot from my 50# @ ~6"bow pistol.
Was I right, did it work?
I've just put it up on Youtube:-
