Gee im old! I got my license like 2 years ago. Well I have my own 02 Ford F-150 (That I Make Payments On!) and I never have to worry about driving on ice because where I live we haven't even had a good snow in like 4 years and it never gets below like 40 degrees in the winter...

Ok... Not all ammo needs to fit inside the barrel... If you are using a pen tube for the barrel just use the pen cap as the ammo. Don't smash it on the end or it wont come off and you will end up blowing off your end cap ( like i did :shock: ) but just slip it over the end and just a little snug ...

I basically made an exact clone of this gun for my first spud gun!!! It works great and I wouldn't even dream of changing the trigger system. It may be an extra 5 bucks for batteries but it is so worth it when your trigger looks like it was made by the military. what I like best about this design is ...

I don't think their would be a problem with using that pipe pyromanic13, most metal pipes have such a high PSI rating that you could almost never reach it with a potato gun, and unless you find huge rust pits in it I doubt the integrity of it has deteriorated much.

yeah i agree with julz on the point that my pneumatic takes about 3 minutes to preasurize where as my combustion takes about 7 seconds.... with that said i still like the phneumatic better because a potato shot 100 yards beats one shot only 65 yards any day of the week!

OK solid steel or copper pipe would probably hold up just fine. But as we have affirmed in the past ... sch.40 and other PVC products don't do well under low temperatures and considering dry ice has a surface temperature of -78.5C (That's -109.3F) I would rule it out as a good building material ...

Personaly i think dry ice would be too hard to controle... You would need to have the exact same size peace with the same amount of water each time. Too much of eather and not even a solid steel cannon will hold back the preasure (Kabooom!). any way if you came up with a good system to regulate the ...

At work we use "Gum Remover" to get gum off of walls etc. Upon looking for a new fuel for my mini I was looking through arousal cans and found that this stuff is made of propane and butane so I knew it was extremely flammable. I tried it once and it went further than any other fuel than I have ever ...

I use butane in my mini and if you experiment with a lighter enough you can even get in down to a science (exactly 7 seconds on mine :D ). Secondly, if you use spit wads don't chew them to a pulp and they should work just fine. I also use ice bullets, formed from another tube and forced out with a ...

Yall need to try super balls... you know the little 1 in diameter ones that are easy to shake out of quarter games. I covered one in lotion for lubrication and shot it at a brick wall from about 30 feet. the ball bounced over my backyard fence, 50 feen away, and the last i heard of it was brushing a ...

I hope you don't mind but I used your electric solenoid idea to build my own cannon. At first it was basically the same cannon but I am slowly modding it into a new creation. Well, thanks again for the plans and I hope that soon I will have some awesome pictures to show yall of "The General ...

Ok so I know that a big spark or a lot of sparks helps the accelerant ignite.... But at what point does 100,000 volts become necessary Oh well i have a phneumatic anyway.
