| | + | Welcome to The Spudding Handbook! This wiki format handbook contains all of the information you will ever need to build spudguns, and much more besides. The purpose of this handbook is to explain the principles of spudguns and how they are built and operated. All of the information contained in this handbook is free and available to anybody who wishes to view it. |

| | + | ==What is a Spudgun?== |
| | + | ''Main article: [[What_is_a_spudgun%3F|What is a spudgun?]]'' |
| | + | |
| | + | |
| | + | There are many different names for spudguns. They are called potato cannons, spud launchers, potato guns, spud cannons, and a host of others. Whatever you decide to call it, all of the aforementioned describe the same type of device: a device used to accelerate a [[potato]] down the [[barrel]], and launch it some distance. While it may offend some purists, the humble little potato is quickly losing favor to other ammunitions such as [[golf ball]]s, [[tennis ball]]s, and other cheap, uniform projectiles. |
| | + | |
| | + | ==Types of Spudguns== |
| | + | |
| | + | |
| | + | === [[Pneumatic_launcher|Pneumatic Launchers]] === |
| | + | |
| | + | These use the energy stored in compressed gas to launch a projectile. The launcher's [[chamber]] is [[pressure|pressurized]] and the gas held back from the barrel by a [[valve]]. When the valve is opened the gas is allowed to rapidly expand and escape down the barrel forcing the projectile out before it. |
| | + | |
| | + | === Combustion Launchers === |
| | + | |
| | + | * '''[[Combustion_launcher|Regular Combustions]]''' |
| | | | |
| | + | These find the energy needed to launch a projectile from the [[Combustion process|combustion]] of a gaseous [[fuel]] and air mixture. The fuel is added to the air already in the chamber, the chamber is sealed and the mixture ignited. This combustion creates a pressure spike that forces the projectile out through the connected barrel. |

| − | [[What is a spudgun?]]
| + | Hybrid launchers are a special type of combustion launcher that use a pre-pressurized fuel/air mixture. This results in a higher pressure and hotter combustion on ignition, thereby transferring more energy to the projectile. |
| | | | |
| − | [[Combustion cannon]]s | + | === [[BB Machine Gun]]s === |
| | + | A [[BB Machine Gun]] (BBMG) is a device designed to shoot a large volume of small diameter ammo, typically plastic airsoft or steel BBs. BBMGs are pneumatic guns but unlike single shot launchers they require a constant gas supply to function. |

| − | This website is here to teach you about potato guns, also called spudguns, spudzookas, and spud chuckers. So far there are pneumatic, combustion, hybrid, and BB type cannons/launchers. Here you will learn all about spud safety, how to make things like breech loaders and what types of fuel to use in your spud gun (like propane, butane, hairspray, rightguard, etc.). You will learn the good and bad types of ammo to use as well as learn the best types of ignition (like stunguns, flint ignitors, BBQ ignitors, etc.) and how legal your cannon is. You just may learn how to get something totally free. You will learn about ABS and PVC pipe and how to correctly mount a pressure gauge into your cannon. You will learn all about the different kinds of valves and how to use them. (sprinkler valves, diaphragm valves, pistons, etc.) You will learn how to make a hybrid and a pneumatic/combustion cannon. You can even learn about strafers and submachine BB guns! Above all you will be able to find instructions on how to build things that you will love for years to come. All of this is totally free so be happy and get on to registering and posting!
