Here is yet another propane injected spud cannon. It's not anything special but it's simple, sturdy, easy to build, and launches huge potatoes well over 300 feet.

Single ignition works pretty good, might try dual later.

Spudstuff you mentioned you do it without a regulator does it work good that way?

You can get by but the problem is that when the pressure in the can drops it effects the performance. I would always reccomend using a reg.

I charge the 12 inch x 1/2 inch injection pipe to 40 psi. It's the most powerful to cosistent ratio i've found. I have fired a 60 psi charge and it blew the potato into tiny pieces as it came out, but it misfires a lot any higher than 40 psi due to incorrect fuel to air ratio. The chamber volume is roughly 300 cu/in and for it I used 4" pvc the barrel is 2". I could have used a longer barrel but it think it looks better this way and is easier to carry.

Thanks spudstuff.
But I don't like spending money.
So I guess ill set up a propane injection and buy a reg another time.
So i guess ill make it upgradable.

Kudos for the nice green and very interesting Van Goh(sp)-esque stand.

Sweeeeeeeeeeeeeeeeeeeet!
Do you have interchangeable barrels on that? A chamber that size could launch some heavy things pretty far.
