Guest 240hybrid Posted August 14, 2003 Share Posted August 14, 2003 http://spudtech.com/detail.asp?id=26 I thought I made some cool patato launchers...check this thing out. Quote Link to comment Share on other sites More sharing options...
Guest comeandzpa Posted August 14, 2003 Share Posted August 14, 2003 wow.....thats pretty high tech for a potato launcher. My friends and I always just used a piece of PVC piping, a can of hairspray or other highly flammable material, and a click-style lighter. Not the safest, or most efficient, but we could send huge wads of aluminum foil over our neighbors' houses...good times! Quote Link to comment Share on other sites More sharing options...
Drax240z Posted August 14, 2003 Share Posted August 14, 2003 That is just cool. Me and a bud made one similar one night at work on a very slow nightshift over the christmas holidays. We used 3/4" PVC pipe for the barrel, and did a nice pressure chamber. Pump it up with shop air and you could walk around with it. Well, we also had the perfect ammo. 3/4" stainless steel sphere's that we used in our ball grinding mill. After building this thing, we decided to test it out. First test was to grab a sheet of 3/4" plywood, stand it up in the shop, stand back about 60 feet and crouch behind a bench. FIRE! Holy crap, through the 3/4" ply like it was nothing! Uh, wait a minute. Through the hole in the ply was a nice view of our (unoccupied) welding booth. There was a big hole in the gyproc... which lined up right in line with our very very pricy TIG welder. Uh-oh. Turns out we got lucky, between the welder and the wall we had the rod rack, made from 1/2" plywood and full of welding rods. No damage to the TIG. However, the shot went 60', through a 3/4 sheet of plywood, another 60', through 2, 1/2" sheets of gyproc, and halfway into a piece of 1/2" plywood after that. Needless to say we were more selective about where we used that thing from then on. Quote Link to comment Share on other sites More sharing options...
CruxGNZ Posted August 14, 2003 Share Posted August 14, 2003 Now that's cool! I bet you that the inventor of Poly Vynil Chloride never saw people all over the world using PVC to make personal Howitzers . Edit: Damn Drax, that's crazy! What was the PSI you pumped that thing up to? !M! Quote Link to comment Share on other sites More sharing options...
Drax240z Posted August 14, 2003 Share Posted August 14, 2003 Or chlorinated poly vinyl chloride for that matter. It wasn't a huge amount of pressure, I think maybe 120psi was the max we could coax out of our shop air system. The secret was the 3/4" SS ball and the tight fit, combined with a long barrel, quick trigger opening and a fairly big resevoir. Quote Link to comment Share on other sites More sharing options...
Guest 240hybrid Posted August 14, 2003 Share Posted August 14, 2003 yeah me and the buddies made one that had a 4" chamber and a transition piece down to 2". Potato fit in the thing perfect. It used the ole lighter fluid or hair spray in a hole that was drilled in it. Thing put on quite a light show at night, shooting 2' flames out the barrel. Made a nice bang too.

Guest BigWhyteDude Posted August 15, 2003 Share Posted August 15, 2003 at some big sanario paintball games ppl bring "tanks" that have one or more air cannons like those that they use to shoot paintballs out of. Its really fun to pepper a whole bunch of ppl at the same time with one shot THose are cronoghaphed to where they shoot at the feild limit as far as FPS though so its reletively safe. Really fun:) Quote Link to comment Share on other sites More sharing options...
