Hey, any of you guys ever made one of these things. They are so awsome. I made one today and it shoots atleast 350ft in the air. What i did was get a 2 inch pipe. Use a 2 in to 4in reducer and made the chamber about a foot long. Put a screw on cap on the back. For ingnition i have to screws drilled in so that they are just about touching each other. I use a grill starter with the wires to the screws and that makes the spark. Spray some cheap hairspray in there and caboom. this thing fires of. So far i only shot a couple potatos. Most of the shots ive used a golf ball wrapped in duck tape to fit the barrel. You guys need to make one of these because they are fun as heck.

 

Yup, I got one. Made it out of PVC pipe. Barbecue igniter for ignition and spray antiperspirant for the juice. Launches spuds a lonnnnnng way! I beveled the end of the barrel on the lathe at work so that it cuts the spud when you ram it on the end of the barrel. Makes a perfect fit so none of the propellant gets out. It's a lot of fun.

 

could one of u guys pm me with detailed instructions on how to do this, i always wanted to make one.

 

Be carefull and never ever use starting fluid or anything other than hairspray as propellent!
There is a book called "Backyard ballistics" which covers this and many other WAY cool devices.

 

I accually shot a potato thru The side of a friends House Oppsy, Thing are very dangerous Be carefull, Shot an Egg once It accually flew good

 

My Brother-in-Law says he can make a killer Potato Gun. But he won't give me instructions because there illegal [img]i/expressions/face-icon-small-sad.gif[/img]

 

I had several of these once. Had long barrel, short barrels, large and small chambers. My favorite was my 4.5FT barrel with 1.5FT 4 inch combustion chamber. I shot through my buddies oldsmobile radiator with it!!!!! They are simple to make and I can try and make plans for you if you want, just PM me. I do prefer the Coleman lantern type igniters over the BBQ igniters, they are more reliable, in my experience.

 

Apples make the best ammunition. The kind of "self lubricate" themselves and make a perfect seal. [img]i/expressions/face-icon-small-happy.gif[/img]

A guy up at the lake had one and shot raquetball *****. They fit perfectly in the barrel. Went a mile. Be careful with that kind of thing, if your fuel and barrel pressure exceed the strength of the combustion chamber you might be hauled off to ER.

 

my cousin made one with the card bored from a silage wrap. but we could never get it to work becasue the hair spray or starting fluid would never ignight. so we just used propain and oxigen and tha really shot that duct tape ball far.
