METAL SPUD GUN - 3 ASSORTED / ONLY 1 SUPPLIED

Product Information

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. Soldering: commonly used in the construction of copper pipe based spudguns, a solder with a lower melting point than the copper is melted and drawn into the gaps between pipe and fitting with capillary action, holding to pipe and fitting with a wetting action before hardening. To get them on any certificate you would need to take it to a police station and get it certified which would of course have to include why you need it, where you're going to use it and how you're going to keep it safe. Aluminium: Aluminium is a lightweight metal with good corrosion resistance. Aluminium pipes are sometimes used as barrels on spud guns on their own and machined aluminium is a popular material for particularly unique designs. Golf ball launchers: at some charity outings players can make a donation and launch a golf ball over 300 yards and use that as their tee shot. Usually the vendor hired by the event organizer launches the ball for safety and liability reasons.

If you have your own land and plenty of space to use if safely... i can't see a scenario here you would be arrested for possession of a spudgun...

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. 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.

A spud gun is not considered a firearm unless it fires a projectile faster than 152.4meters per second and at a muzzle energy exceeding 5.7 Joules based on the definition of a firearm in the Canadian Criminal Code. [2] A spud gun may be interpreted as an imitation firearm, and therefore it would be illegal to have it in possession in a public place. The spud gun would most likely be considered a dangerous weapon, and therefore if an offense is committed with it, a possession of a dangerous weapon charge could be issued.

now if you live in a top floor flat and start shooting potatoes out the window across a built up area.... i can see that problems would arise... Didymus, JohnThomas (2013-02-06).

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 ]How legal is this device? Would it be considered a firearm, as it 'fires' ? Is it no more legal than going to a park and igniting hairspray using matches, even though this all happens in a confined area? It is rare for a spud gun to be powerful enough to break the sound barrier, although there are some cases of this happening using specialized designs. The spud guns used are typically hybrids; but some pneumatic cannons have achieved the feat, either by using a special low-density gas, such as helium, [20] or high pressures combined with a fast valve. [21] There is also one reported case of a combustion design achieving super-sonic velocities. [8]
