If you have to ask others instead of doing the research yourself and learning the reasons behind how it is made, you will probably injure yourself or somebody else trying to make and use it. Want to make a cannon? STUDY! when you're done, STUDY some more! This stuff is not secret knowledge and is pretty easy to find. Work for it.How can my friend make a homemade Black Powder Cannon?
if you are looking for a big bang for little cash take a 1 1/2'; piece of black iron pipe that is about one foot long cap one end and drill a 1/8'; hole in the cap and u r good to go. CAUTION I AM NOT SURE ON THE LEGALITY OF THIS CANNON AND I CAN'T GUARANTE YOUR SAFETY HAVE FUN!!!!!!!!!!!!!!!!!!! Report Abuse

The best result i have seen involved using c-900 cast iron pipe caped at one end with reinforcing rings, but again you dont really have enough detail of what you are looking for, such as diameter, target muzzle velocity, shot, length allowance, or even what type of suspension you want.
