i have one i made.the one thing is DO NOT use pvs pipe.pcs pipe is really thin and has a really good chance of exploding after a few shots. use the black abs pipe and it works wonders.just get a tube about 3 feet long in the front glue a chamber on the back of it with a lid, drill a hole and securly glue on a b-b-q sparker and voile,you have yourself a gun

its simple
use a 4 inch by 2 foot section of pvc for the combustion chamber
put a screwable endcap on that
use a pvc tapering part to atact the barrel
taper from 4 inch to 3 inch and 3 inch to 2 inch
put a barrel on and you have a gun
the barrel should be 4 to 6 feet
use some skrews and a bbq lighter for the ignition
its fun

i apologize for the awful quality (yay for ms paint)

overall just keep it really simple and itll work

Are you kidding me? ABS is what wiring goes in. PVC can hold 200psi.

use pvc it works fine..just steal/buy a bunch of grill ignitors because they usually break after a while...and sharpen the end of the barrel so you just push the potato in and it will cut off what doesnt fit and be the perfect size

haha we where shooting mine at a house under construction so it was just the wood up so far. We where shooting from quite a ways off and we thought the pottatoes where exploading when they hit the house. Anyways we went up and looked at it and the house was full of holes. Much more powerful than we expected. We then left imediately

i got a sweet, made out of pvc, its got a 4 foot barel made out of 2inch pvc and the combustion chamber is made out of 3 inch pvc, then i glued a screw on pvc cap so you can open it and spray in hairspray then close it off and click the barbecue ignitor. make sure evrything is tightly glued, believe me they have power. Mine shoots a good 200 feet EASY and with alot of power, thats just with the gun pointed flat, if you tilt it up itl fly halph a kilomiter (did it at my lake and went into the middel of a small bay)

Thats like exactly what I did. Ours had a flexible joint at the barrel so we could aim it a little more precisely. I'd also recommend getting a screw cap end for the firing chamber, it makes it a whole lot easier to clean and fuel. Make sure to drill a screw through the barrel so potatoes dont fall into the chamber. Also, let the glue dry, my friend almost took his face off after test firing the BBQ lighter in its newly created home. Good luck, and dont let the threads on the cap catch fire!
