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...

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...

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
