Since I can't make an engineering decision a priori, I'd put the burden of proof for a safe design on the team via <R94>...

Hi Mike,

Is your concern that the end of the cylinder may break loose upon impact and become a projectile or otherwise create an unsafe condition?

If the kicker design includes a mechanical stop that prevents the piston from slamming into the end of the cylinder would that address your concern? In other words, in general would that meet the "the burden of proof for a safe design"?

I ask this because many many teams have built, or are busy building, kicker designs with pre-loaded cylinders.
