Electric Pump Powered Spud Gun




Introduction: Electric Pump Powered Spud Gun

It is a simple ball valve pneumatic spud gun but instead of a hand pump it uses a 12V electric pump (originally a car pump), I reconnected it to a 12V battery I had laying around (as you do), it uses a 2.25L bottle for air storage I suppose. By the way it uses a hell of a lot of duck tape! just something to keep in mind. it refills in about 10 - 15 seconds, compared to pumping for about 1 - 2 mins.

    You are right. Use only old fire extinguishers and metal pipe.

    thanks, it's been upgraded to a straight line style gun, with an air compressor quick release valve to the air pump with a blow-off valve so it has constant preassure to smaller air tank

    How much bar does it give? and how long does it shot? Thanks a lot

    its an electric car pump that I rewired so its movable with a 12V battery. thanks for commenting

    I did the same thing a while ago But i took the pump out of its case took the Psi guage out and put it on the bottle .

    Then put it in a big piece of pipe
