Hi there !

On youtube i saw those big spudguns and wanted to build one by my self.
Yesterday i made a little one of PVC.

The barrel (16mm PVC) exists in two parts so you can load a paper arrow easily.

Screw the bottom of, fill it with gas from a light, screw the bottom on the gun. Ignition and BANG !! the arrow fly's beautiful through the air. :)

For ignition i use two different things.

One is a Piezo ignition from a lighter.
But it doesnt work that good.

Other one is a coil from a car.
It works very good but it has many wires and needs 12v.
