This is my second spud gun! It is made from PVC ! Pipes are made in Germany.
Components: 1. 50mm pipe as barrel
2. reducer from 50 - 110mm
3. 2x elbow 90 degrees 110mm
4. 2x female-female things 110mm
5. 110mm cover
6. small PC fan
7. screws
8. for fuel I use the hairspray.
I wan to ask you guy's which is the best fuel for gun like this ???
This is one test video where I was shooting with newspaper...
That is one monster chamber you've got on that thing, way overkill for your barrel. I assume that opening on the side of the chamber is where you will spray in your fuel.
Grind a knife around the opening of your barrel. That will make it easier to load potatos into the barrel and they will fit more tightly in your barrel.
I would normally recommend a propane metering system but with the size of that chamber you probably should just leave it as a spray and pray.
Build yourself a new cannon with a smaller chamber and propane metering system using techniques you find on there pages.
really nice gun, i like where you have the handle with the built in ignition and fan switch, pretty clever. any idea how far it launches your ammo?
and the smiley face fits perfect! lol.

I don't know because I have this gun about a week so I have lots of tests in future... Old gun was shooting around ~ 80-90m (250feet) Maybe this gun can do something more
If you say that chamber is too big maybe I need smaller barrel or use this size just get it longer ???
I know that propane will be better but It is quite expensive - tnx for idea!!!
yea and about that barrel opening - I know , just I haven't done it jet !
Without getting exact here, just cut that chamber in half and add maybe .5 to 1 meter of barrel length. You'll gain performance and not gain any overall gun weight.
Propane is only $2.50 US for a 14 oz tank in Amercia, probably a little more expensive in Germany. However, one tank will more than likely last the life of the gun...and will burn cleaner and look cooler..
