Fletcher's SpudGun

a.k.a. Starch Resource Deployment Facilitator or Kartoffelkanone

Disclaimer: Please be cautious when building and shooting spudguns, they are very dangerous and should be used for
recreational purposes only. I am not responsibile for what you do with the information on this page!

Background Details

I started this project in the fall of 2000. The gun is 12' long and it uses piston/quick exhaust valve technology with compressed air. I am constantly adding or upgrading parts to improve it's performance.

If you want to build a spudgun, the links below will get you started.

Spudgun Video  

A 40 psi shot at Barney.

Quicktime (256Kb)




01/25/02 I ran a couple of successful test shots at 80 psi, in addition to tweaking the piston.

11/24/01 I've attached the new coupler and adapter.

06/11/01 In order to fix my gun's two main leaks, I have decided to cut off the leaky adapter and get a new one.

05/03/01 My Spudgun failed me when I tried to shoot it at the sailing party. I am replacing the electric valve with a manual one for simplicity's sake.

03/25/01 I made a video of a 40 psi shot, but the piston was leaking.

03/17/01 I "finished" my spudgun!

02/01 I bought an air pressure guage, and am using a piece of rubber air hose(fig. 4) to attach it, to protect it from physical and pressure shock.

01/24 - I came up with a new piston design, it uses a rubber stopper instead of a diaphragm, and a check valve inside.
