T-Shirt Cannon

My reasoning is behind... I believe Newton's Third Law: With an action force comes a reaction force. As cannon fires the shirt, the shirt "fires" back with the same force to the cannon. Therefore after several shots out of the cannon, that rod its mounted on will bend significantly.

So yeah, I would strongly advise to mount the cannon onto something sturdier to stop this from happening.

Well the main reason was to allow for a 360 degrees of motion and to allow perpendicular shooting to the wheel base. However at second glance, I can see many ways to raise the second mounted bearing in order to lessen the moment on the steel rod. I have thought about the "recoil on the cannon" as 50 psi on a 3in diameter item is not a small amount of force.
