i want to make a pair of combustion spud guns that run on axe or propane that i could dual weald without breaking my arms, can any 1 give me some basic specs on the sizes and materials needed

i dont want them to be more than 18 inches long and no more than 5 pounds each

just how much were you going to sell it for?

my cannon has an 18 inch ling chamber, a 24 inch barrle and one set if sparkers. my question is, how do i shoot multiple paint balls or airsft b.b.s all in one go without having any melt, fall out prematurly or pop inside the gun. i want quite a large spread...enough to light up a 10X10 foot peice o...

nicly done, im glad to see that some people keep to the "keep it simple" rule of spud gunnin. i dont care what people say, no matter what you do tou your cannon, its still a spud gun, there is no need to go all high tech...well done

sweet...ill try to make one and then ill post sum pics

the barrles are the size of a bic pen, it is combustion, and the bottle would be the size of a gatorade bottle.

i was planning to make a multi barled mini with a small plastic bottle and some pens.
how many barrles could i get away with?

p.s. i want it to shoot in shotgun spread pattern

the launcher is made out of a film canister, a pen tube, two thumb tacks and a bbq lighter...and is held together with electricians tape and http://img3.imageshack.us/img3/5043/008bht.jpg http://img9.imageshack.us/img9/2730/007irn.jpg http://img3.imageshack.us/img3/461/006uxy.jpg http://img21.images...

unfortunatly i am using cellular core, is there any way to make it stronger or do i absalutly have to throw it out and start from scratch?

the piping is sch. 40 abs, the chamber is 20 inches lond & 4 inchs in diamiter. the barrle is 4 feet long & 2 inches in diamiter.the connection between the 4-2 inch peices is a single peice.the whole cannon is glued together with primer and abs cement, and has set for 24 hours. i use a bbq ignition ...

i just built my first spud gun, and for a test i dry fired it with green gas (aka propane) and it was extremely loud and had a nice kick on it.

i am now afraid that if i put something in the gun it will explode...should i even try launching something or am i just paranoid, what should i do?!?!?!

thanks...it kinda smelled like propane

i have found that a gas that is used to power airsoft guns works quite well for launching spuds...its simply called green gas and you can find it at a piant ball or airsoft shop for around 15$

i belive it works better than anything else i have found, and i thought i should let every one know about it
