That is eerily similar to my first, but better constructed :D The only issue I see is fueling. It might be hard to get the right mixture in that size of chamber if it is spray and pray. You'll probably find something that works, though. Nice first build! For the future, think about a chamber with a reduction to the barrel.

It would have been a bit better to tap a hole where there's more than one wall of PVC, bt still not bad. What's the diameter, 3 inches?

Looks good.
The less fittings there are, the less fittings can fail. Simple and safe.

How far do you shove down the ammo?
In other words: Whats the C:B ratio?
The cool thing about this gun is, that as long as you dont build in a "spud stopper" (a bolt to prevent the ammo of going into the chamber), the C:B value is variable and you could find the optimum for different types of projectiles.

like my "one tube" design, yet to be made. you only need to make a "stop" to define the barrel and combustion chamber.

drill a hole where you want the barrel to end, insert a bolt and nut as a "stop".

it is a simple design, and it should work well, just figure out you C:B ratio.

KUDOS on your KISS design.
(i'm unemployed at the moment, food comes before fun, i will do a few videos tomorrow, try out my "pea shooter" barrel, 2.33:1 C:B ratio, should kick major a$$.)

mateee nice build. im not usually in to combustion, but yours caught my eye.. i havent seen a cannon with no chamber reduction before :wink:
i saw that all the parts are like the stuff i can get here in australia, and the other guys from America and everywhere else have like, different looking DWV fittings, if you know what i mean. i was wondering of your from Oz too?

Welcome to Spudfiles,

well.. how powerful is it?
if it's weak, then just use a bigger chamber.

welcome,

we seem rather similar, im metric too and im pretty new

i like your simplicity and if you said it shoots over 100meters then its very good, especially if you are not using some kind of special ammo but just cans and toilet paper rolls, what kind of prpellent are you using?
