thanks for the input guys, i diddn't think the plans were that nice but ok, thanks any way, ok first i have an edit, the 3/4 ball valve is actually 3/8, sorry, ok thanks for the c:b raito idea & link for fuel ratios, as for the electronics i think i'm going to have to make the back half non- removea...

ok here's my idea, keep in mind these are just concpetual, not to be taken as finished product, so they are most likely not completely accurate to scale or design, but a rough draft if you will, feal free to hit me up with questions or suggestions, first up is the basics of the ignition system & fue...

well turns out my plans have to change again, apearently they only make pvc in 1/2'' increments, so im going to have to go with 1 1/2'' barrels, but i've figured out what adjustments i have to make so it's not that big a deal, also i've decided to add a couple more smaller ball valves to the gas sys...

ok, sorry for the @ symbols, my bouble barrel design is going to basically be two cannons put together, so i can fire them independently, my plan is to hook up some toggle switches that have terminals that arent too close to each other so they dont short out the spark, either that or cover them in s...

thanks, not sure about a pneumatic, the only pneumatics i know about are with paintball guns (i used to be a gun tech @ a store i worked @), i may do some more research into it though & see what i can do just for the exp. went with combustion first cause it seemed the simplest to do at the time, as ...

here's a quick pic of what i'm sadly reduced to using untill i can get my SPUDr II up & going but hey it works, i can get spuds about 200ft out, all i did to it was change the back & make new lowers, i'm going to use the originals on the new gun http://i15.photobucket.com/albums/a384/Spiked_Bad_Monk...

yeah, the smoking wasn't a bright idea on his part, i dont smoke so i dont have to worry about it, i'll make sure that doesn't happen next time, that design had a few flaws as i quickly found out, there's not much room for the exahaust gasses to escape so my next design is deffinitly going to have f...

yeah i've been doin alot of research, got most of my inspiration & ideas from youtube, http://www.advancedspuds.com, http://klugeboy.net/, & of course on here, apparntly there's alot more to spud guns than ppl think, i for one had no idea it could get so intricate & complex & yet be so simple & inex...

i'm actually working on a double barrel, propane injection design, that was just my starter gun to get a feal for what to do, what works, & so on, i'm really starting to get into this whole spud gun thing lol

here ya go, i couldn't figure out how to get the vid in the post so here's a link

thnx guys, like i said, i'm not done with it yet, i am going to paint it, & cut some vynil for graffics, maby add a few other asthetcis, & maby build a double eventually, but thats all in the future

hey folks, i'm new to this forum & this recreation/hobby whatever catagory it's placed under, anyway, a friend & i were watching the special features of a movie & they messed around with a spud gun, & we thought,"that looks easy enough to build" so we did, we both have one & i'm hooked, here's my fi...

very nice, slo-mo is freakin awsome

gotcha, guess i diddn't pay attention to the time stamp, i'll get some pics & vids together & start my own, it's a shame, i was hoping to see what the finished product of his was going to look like
thanks guys

here's what i've got so far, i've still got some asthetic details i need to add, (shoulder stock, paint, ect.) but it works pretty well, i'll try to get a vid up this weekend, lmk what ya think
