Improvised Firearm
Improvised firearms (sometimes called zip guns, pipe guns or slam guns) are firearms manufactured other than by a firearms manufacturer or a gunsmith, and are typically constructed by adapting existing materials to the purpose.

Fire Piston
A fire piston, sometimes called a fire syringe or a slam rod fire starter, is a device of ancient Southeast Asian origin which is used to kindle fire. It uses the principle of the heating of a gas (in this case air) by rapid and Adiabatic process, adiabatic compression to ignite a piece of tinder, which is then used to set light to kindling. Description and use A fire piston consists of a hollow Pneumatic cylinder, cylinder sealed at one end and open at the other. Sizes range in length from 3 to 6 inches (7.5 to 15 cm) with a bore about 0.25 inch (6–7 mm) in diameter, to 10 to 14 inches (25 to 35 cm) with a bore about 0.5 inch (14 mm) in diameter. A piston with an airtight circular Seal (mechanical), seal is fitted into the cylinder. A string packing lubricated with water or rubber gasket lubricated with grease is used to create an air-tight but slippery seal. At the end of the piston is made a small cavity where tinder can be inserted without it being crus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
