Unread postAuthor: BigJon » Wed Jan 02, 2008 11:51 am

This is my newest and biggest pneumatic cannon. It is the first gun I have built that was designed just for potatoes. I have only got a couple shots off this morning so no damage pics yet.

Here are the specs:

Barrel: 4'x1 1/2"
Chamber: 3'x2"
C:B: aprox. 1:1
Valve: 1"sprinkler valve

sorry for the bad pics but here they are:

Yeah I was going for simplicity on this one because of my low budget. I built the whole thing for under $30 :lol: and it still packs quite a punch.

Cool can't wait to see how it turns out!

On another note I was thinking about painting it because I have some grey and some flat green, any suggestions?

Your cannon looks great, nice and simple. I believe you used these plans, correct?
Basic Pneumatic Cannon
I used the same ones to build my first cannon:
