Spud Gun Crew!


GonneVille

Recommended Posts

i have one that i made that is pretty much bad ass. It was powered by a 100,00 volt stun gun for ignition and has 3 points where it sparks in the tube for even ignition of the propellent. I used to use hair spray but then switched to propane. I have a setup that i calculated the exact air to fuel ratio and came up with the exact amount of propane needed. I also have interchangeable barrels and different grips for it. The last time we shot it the potato would go about 5-6 football fields i shit you not. It would hurt to fire. I have pics if anyone wants some lol

Would you care to post a video?

 

I was probably 15-16 at the time. No videos.

 

Steps for successful killing of a bird via potato:

 

1. Find bird on power line

2. Sneak up bird as close as you can. Preferrably with cover

3. Shoot bird

4. Laugh uncontrollably at cloud of feathers

5. Try to find bird

6. Upon successful finding of bird, stuff bird in potato gun and shoot it

7. Laugh uncontrollably, again.

 

 

Takes practice, but my cousin and I got pretty good at killing them. Most shots were taken within 20-30'. I remember we could consistantly hit the 'O' on a STOP sign at 50'. :bangbang:

Can you toss it two fields over? not bein an ass, thats just how far yer tater cannon needed to go. back in the day.

 

just the basic design+ aquanet and a bbq igniter. fun fun fun

 

Heh, not totally sure how far the combustion cannon will go. I know for sure it's at least 300yards.

The air cannon, I'm not sure of at all. I only got to fire it once today cause of the lousy weather, and at 100+psi, it blew a golfball clean through a sheet of 1/4" plywood.

i once sent a spud 500 yards with oxgen and acetylene, needless to say i had a 15' lead on my kill switch behind cover. good thing too, we didn't get the back screwed on all the way or we cross threaded it and it blew off about 20 yards.

Yeah, I'm a little scared to try acetylene or ether. I might try straight propane, but only when I build a stronger cannon. The hairspray cannon I currently have is low-pressure sch40. I need to pick up some more of the 230psi rated stuff I'm using for the air-cannon before I try anything more powerful.

 

BTW, I think most of us in this thread have access to actual fire-arms, so why do we still get such a kick out of messing with PVC and hairspray? I mean, is it the DIY aspect? Some inherent redneck genetic thing? Why the hell are these things so DAMN fun?:grin2:

I made a dry ice cannon when I worked for a dry ice distributor in the south end of Columbus. For the most part it looked just like a spud gun but it had no igniter. I used a section of 4" necked down to 3" barrel. For the explosive charge I used a 20.oz bottle with dry ice nuggets/water and the projectile was a tennis ball. When it went off it sounded like a cannon. The projectile left the barrel so fast, you could only see the ball as it dropped in the distance.

I took it to my brother in laws farm to shoot it, I would say it shot a 1/4 mile easy.

 

The only problem with this design is if the bottle does not explode you need to leave the gun alone for a day or two so you don't get hurt unloading it.

I hadn't thought of doing it that way. Gotta be a hell of a bang when it goes off.

 

Anyway, got a few vids of the new pressure-cannon today.

BTW, my buddy there is deaf, so forgive him the odd sounds in a couple vids.

This one (golfball) went through a chunk of 3/8" plywood, then through the 1/4" plywood sheet behind it...

Potato, chunk of 3/4" plywood. It didn't go through the board, it blew it in half...

Finally later on, I found an old rusty trash can at my parents...

The video is really dark, but the trashcan is on the right, you'll defintiely notice it when it disappears...

In high school we had to make an air powered something, or a catapult. We only had to go 30yds with air power and you could only use a bike pump to pressurize it. Needless to say, with experience we went 172 yds, into the apartments on the other side of our stadium. We still hold the school record, and we were the intro to physics class....not the AP calc-based physics class lol. This year the closest was 115ish and it was the younger brother of Josh, who was part of our group of 3.
