Sorry for my bad english, but I'm french ^^.

Ahahah you know it isn't !
It shoots at 350 meters (powerfull toughts), but a pneumatic with the same size will shoot over than a km ahaha.

A km with a cannon that size is unlikely :lol:

It's all very nicely put together, the cut down fan for the chamber looks like something I'd like to have on my desk :)

Where did you find how to make a spudgun by the way?

I'm sure you can shoot at over a km with the same size with high pressure rated PVC... (if you put like 250 PSI in it)..

I saw for the first time spud guns with Youtube, and then I wanted to make mine...
I learnt with forums (patator.frbb.net -french forum ^^-).

Nice cannon, I like what you did with your fan :)
Though I prefer to keep the frame around it so I can squeeze the fan in and that its held by friction.

Also, its nice that you can also use it as a pneumatic.
Why can you only do it up to 50 PSI pneumatic??

Now build one of steel and combine the two at the same time (hybrid) :D

Because it's in PVC, and it's not pressure rated...

The green light is the LED for the fan :D.
When the fan is turning, the LED is lighting :P.
