I've seen potato guns in a lot of mtb flicks. Now tell me: How do they work and how do you build one?

Lots of info out there, just google it. Mine was made from 2" schedule 80 pvc with a 3 foot barrel for portability. The chamber had a removable cap on the back where the AquaNet was sprayed in. It was fired with a gas grill piezo electric ignitor.

just google it.
also, bevel the end of the barrel so that it cuts the potatoes to fit.

brings back good memories.........

Just remember that anything as fun and cool as a potato gun is obviously illegal

 

[DR. Dirt]

make sure you dont jam the thing, cuase then you have a hell of a time getting all the crap out

Spud cannons rule!

The pneumatic ones own the hairspray ones.

just google it.

Bevel the inside edge rather than the outside edge so it compresses the ammo. neaky:

basic design that works well -- 2" diameter 4' barrel joined to a 4" diameter 2' chamber. Piezo sparker to trigger. Engine starter makes a good propellant; you know, when gasoline isn't good enough :evil: .

oh god, brings back bad memories...

fvcking cops...

 

[.:Jeenyus:.]

Too bad they aren't legal inside city limits

Man I loved my potato gun. I need to build a new one... (that fits golf balls :devil: )

The best birthday present I ever got was a potato gun made out of PVC pipe and gorilla glue, with a ball valve and a presta valve on the end. With about 100psi., it was strong enough to dent a portapotty with frozen brussell sprouts from 100ft. And much better than one using propellants because they don't explode in your face.

helluva chamber you got there!
good call on the internal bevel. mine was on the outside since that's easier to make, just run it on a bench grinder for a minute. how'd you do the inside edge?

 

[Wumpus]

how'd you do the inside edge?

dremel or a file would work.
