Essentially, if you are a 18 year old, in a farm with no one around for 280 meters further than your projectile will fire, and you can show that it is NOT CAPABLE under any circumstance of producing more than the specified power and you are more than 50 feet from any roadway a car can travel on, you may win the court case. In Germany, a spud gun does not differ legally from any other firearm (for ones that use combustion to propel the projectile) or air rifle. The manufacture, acquisition and possession is therefore subject to the same requirements as for any other weapon of the same category. Since there is no known model developed before 1871, which would classify that model as an antique, spud guns are not subject to the eased regulations regarding antique weapons. Therefore any non-combusting spud gun with a maximum projectile energy of 7.5 joules can be owned by anyone without a license, while their manufacture still requires one. The legal possession of any other such weapon requires a gun license. Alternate designs have also been used which use a sharp projectile to puncture the burst disk, like a mortar [16] or using a manual puncturing device to trigger failure of the disk. [17] These allow total control over burst disk cannons without the need for hybrid technology and materials as simple as plastic tape can be used for the disk. Burst disk cannons have also been made which are fired electrically, using a nichrome wire to trigger failure by heating. [18] Connections [ edit ] Welding, soldering and gluing [ edit ]

A hybrid using a fuel and air mix at twice atmospheric pressure is said to be using a 2X mix. Higher mixtures can be used and will produce even higher pressures. The fuel and air need to be measured and matched carefully to ensure reliable operation; hence the use of accurate air pressure gauges and fuel meters. In spite of what you say about your land being in the middle of nowhere, someone will own it and someone will have access rights to it although,I admit, maybe not the public. Perhaps you can get the landowner's permission to fire your cannon on it. Even then you have a duty of care to ensure there are no third party injuries or damage. Someone (and you admit it may be you) will inevitably get hurt. Combustion powered spud guns typically have the least complex designs, the four basic elements of which are: Just make sure nobody spots you and fire the cannon on your or a friends piece of land, between trees and far away from other homes if possible.

The potato cannon can trace its origin to the World War II-era Holman Projector, which was a shipboard anti-aircraft weapon. [7] Launcher types [ edit ] Feel free to shout up and arrange a meeting or pop-in and visit us at our kiosk at Darlington Market. It comes down to what you're doing with it and who you are. A young teen responsibly using a combustion spudgun will probably get talked down and the spudgun taken away.

By the release of compressed gas (normally air) through a valve; such a launcher is typically referred to as a pneumatic launcher, and its power is limited primarily by the pressure of the air supply, be that from a compressor, manual pump or bottled gas.In some jurisdictions spud guns are outlawed or have restrictions on their use and may require licenses and certification of the gun. If the air powered spud gun has soft ammunition (potatoes) that splatter or bounce on impact and is kept under 100psi the spud gun is perfectly legal. [ citation needed] Poland [ edit ] Compared to the operation of other spud guns, dry ice bomb cannons are similar in firing principle to a light-gas gun of the pneumatic type; the plastic bottle performing the task of the burst disk albeit in a less controlled manner. By the explosion of a dry ice bomb placed in the pipe before the projectile, generally referred to as a dry ice bomb cannon, these are limited in power by the materials and size of the dry ice bomb but firing pressures can be around 200–300psi (1.4–2.1MPa). Once again, thanks for the response all. I suppose selling them and firing them on say, a football field is out of the question all together!
