Hey all, I am building a combustion potato cannon for a school project, a 1.5 inch ABS pipe based cannon (yes I know, pretty risky seeing how people see dmw ABS with its pros and cons here, also because I made the mistake of not researching beforehand), posting about it to get feedback and criticism...

Nice job!!!

Well, this is a bit awkward, tried to post this a really long time ago but regardless its on here, much appreciation and thanks PCGUY! :D Regardless, the current cannons design, New stuff: gas metering and injection, the thing is a fairly small but it works well regardless at 20-40 psi worth of buta...

C'est pour ça je suis ravie de participer en continu pour continuer à faire vivre ce monde... De plus en France je doit être l'un des rares à aboutir mes projets avec de réelles envies de continuer des développements ! Les fusil hybride peuvent prouver de belles choses avec du travail et de l'applic...

Good job !

On Suckering In a New Generation of Spudders Yes... I realize it's a completely hilarious/original way to phrase it. Rather than an introduction establishing that I don't think new spudders need to be suckered in, along with other wordy creations, it would be much better to just dive in, givin the ...

Very nice project! Since we're talking about rifling, have you seen how people are using "electrochemical machining" to rifle barrels from steel tubing?

Pretty good for a nailgun! :p I have a few recommendations for the next one, though. That chamber is pretty massive for a 1/2" barrel. If you were to use a smaller pipe size for the chamber (say 40-50mm) you could probably find some better pipe which is either rated for pressure or will hold up bett...

Hello guys. I just wanted to share with you my first prototype for my spud gun and also share my ideas. I made a prototype for my first spud gun but the ammunition is a nail dart instead of a potato. The barrel is about 3ft (approx.) and the diameter is 1/2 inch and it is a blue pvc. The combustion ...

absolutely beautiful gun right there, like how the extended chamber doesn't mess with the overall look that much to it too, nice job modifying it

Excelente trabajo!!!

Noice. I particularly like the refit of the original valve body.
