| Ok this question is impossible to answer without more info. Is it pneumatic or combustion. What is your primary ammo. What range and power do you want. |

@clemsonguy, this is in combustion cannon discussion, therefore it is a combustion cannon also he called it a potato gun, which means it will shoot potatoes.
@toon, a 1.5" sch 40 pvc barrel should fit most potatoes and if you use bigger potatoes then a 2" will work. Most common is 1.5" though. Oops in centimeters... hmm I don't feel like doing the math, lol. |

Im guessing that you are from the UK
Best chamber would be 110mm / 11cm pipe, It is harder to find pressure rated PVC in the UK so if your going with un pressure rated then go with ABS much safer.
Barrel I would go with would be probably 40 - 50mm barrel.
Bigger is always better. There is no replacement for displacement
If your serious about building a good cannon, and not a cheap one with bits you can find, I can put you onto a good few PVC suppliers in the UK
Just private message me because it is late here and I can't be bothered to go searching at this time (12:00 PM/)

My bad I missed that, and most people with spud guns dont shot spuds, Ive had the best luck with 1.5 inch so 4 cm barrels(estimate conversion) and 36 inch 3 inch so 7.5 cm chambers |

boost helps...
Bigger is only better when the fuel burns before the spud leaves the barrel. I recommend playing around with HGDT to find where performance drops off with larger chambers. |
