Your design will work. I have seen other cannons like this that work. Look in the help section and there is a thread on how to modify a sprinkler valve. You're only problem will be that as propane expands it cools and produces less pressure. Taking shots 2 minutes apart will probably be fine. Just m...

The backpack cannon
Here is the cannon i compleated a few days ago. It will launch a rubber ball over 100 yards at 60 psi. I will soon take it up to 100 psi. I want to add a co2 setup but don't have the money now. Currently pump it up with an air compressor or hand pump. I am also going to paint it. So here it is. Vid ...

Landmine test fire vid!!!
Hey guys. This is my version of the landmine that colty-bear made. Thanks goes to him for sending me the plans very early this morning. I quickly modified them and went to get the parts (also this morning). I just took this vid and sent it to youtube. It's an all around view of it. The only real dif...

Semi/full auto ball valve
Hey guys. I was just thinking and had the idea to take a ball valve (probably 1") and plug one end of the ball somehow. Then make it where you can spin it a full 360 degrees around and around (it could be spun by a small drill for full auto). Every time it turned around to the back, where a chamber ...

Also because of the large extra amount of air shot out you might be able to make it semi auto by use of a piston that pushes a bolt back on the outside of the gun like most semi/full auto firearms have. :D Just for added complexity because nobody wants to have to reload between shots!!! :D Although ...

I'm not sure how many times i have thought about that idea but never tried it. It's great to finally see someone else build it and make it work! :D MY idea for an improvement was to make it into a gun style (add a stock) and have a trigger that fires a nail on a spring to pop the cartrige open!!! :D...

CO2 at Lowes
Hey everyone. I was doing my daily roaming of lowes today and i found in the air compressor section that they sell re-fillable CO2 tanks(9 and 20 oz.). You buy a 20 oz tank for about 30 dollars and return it for around 26. They also have a regulator there that is 100 dollars. That is cheaper than mo...
