i had a teacher who helped me make a pneumatic in class. he was really cool

Pneumatics may be safer but i think that the fact that it could blow up in your hand's kind of adds some of the fun to shooting combustion launchers, but i would say pneumatics are all around better guns besides the wait but combustions are much funner to shoot.

the cap was new and wen it blew off and left only the donut thing it only cut my leg a little. the ignitor was staight into the chamber. this is proabbly a stupid question but could i have a metal cap on my gun

im sorry for the trouble but ur not understanding. THe whole end cap didnt fly off just the parts that wornt attached to the threads. the threads were still on the gun but the back end of the sewer cap had blown off.

i have done research i wouldnt ask if i hadnt already. and the threads are still fine it was totally scrued on and the plastic was about 1 cm thik. the and cap was almost the heaviest thing.

OK so i have just recently made my gun. I made the gun and today I did my first test. I took the potato shoved it down the barrel then sprayed hairspray in the other end then scrued the lid and then ignited it. it shot the potato fine it was really cool. So i did it again except this time instead of ...

lol. i live in the middle east as some of you no. my nieghbors dont care. and if they called the police they wouldnt come. IF they did come they would think it was cool.

for u in aus u could buy a lighter that instead of spining the thing on flint that it clicks. you can take out a little thing inside that makes a spark if you squeeze both ends. then on the inside of the combustion chamber glue a piece of metal and put the wire through thatmakes a spark and there ...

pc guy does the larger chamber help for distance ro what does it help.

that thing is crazy. ive heard propane is a lot better and has much more power. im not sure though

thts really cool i like the handle idea. For my ignitor i just used drilled a hole in the side of my gun then put a bbq lighter in the whloe and then put apoxy around the edge to seal it. this way no wires at all. it costs me 1$ for the bbq lighter to.

omg. Sparklers are not lame. flying spud look take about 30 to 50 sparklers and tape them together real tight with the one in the middle sticking up alittle then if you packed it right it has enough power to shoot through a metal pipe or if it is packed wrong a 30 foot flame will come out the top

Theres a guy who had to make a potato gun for the american department of agriculture. The gun had two shoot 8 foot long 2 by 4s 100 feet. The whole thing was for tornado testing. Pics herehttp://www.spudtech.com/. So add 8 foot 2by 4s to the list of ammo

so ur saying put the fan on the inside of the barrel but doesnt it melt

yah all of u guys have a point but nothing to talk about. i live in the middle east. YAH i live across the gulf from iran. i live in the UAE. I had to go to an industrial part of my city to a plumbing store with a guy who only spoke arabic. then i had to talk to himi n arabic for a long time then ...
