It was a cold, sunny October Tuesday, the 17th as I recall, as I sat upon my computer chair, browsing random pyrotechnic websites in hopes of finding something interesting. Suddenly, my friend Justin IMs me, detailing the effectiveness of the launchers he and another friend Tyler had manufactured from plumbing parts. Intrigued, I had to see these for myself.

The next day, after school had ended, I went down to the area of town in which they lived. Soon after arriving, and I had finished examining these fascinating devices, we loaded up with both launchers, a bag of russets, and a can of Old Spice Red Zone body spray, and headed for the lake not 200 yards from Tyler's house.

Consisting of nothing more than a few feet of ABS pipe, 3 fittings, and a BBQ igniter, each launcher was very basic. None the less, I was exceptionally impressed upon witnessing the first shot - the potato left the barrel at an astonishing velocity, and a few seconds later, impacted the surface of the lake with a distinct splash. We spent the following few hours launching spuds towards their mashed demise, and it was then that I realized how a teenager's fascination with fire, explosions, experimentation, and high velocity objects could be satisfied with such a simple, inexpensive device. The following day, I would construct one of my own, which triggered the birth of an obsession.

I suppose my potato launcher beginnings resemble a number of individual's in several ways, but sadly, few can look back upon the past. The desire to modify, improve, and technologically advance our creations brings forth a whole new degree of mental input upon this hobby. Often times, one's most enjoyable spudding experience came alongside a launcher of the most basic construction. I want this thread to be a reminder to all of you; a reminder of what spudding is really about, fun.

With such thoughts in mind, I built this launcher. With a 3" x 14.5" chamber (painted gloss black), a 1.5" x 45" barrel, and a BBQ igniter housed in a simple handle, it is highly reminiscent of the original launchers I witnessed on the day of October 17th, with the only added feature being breech loading. The recollection it brings is truly vivid.

Thanks for looking, and I don't mind if you post your initial spudding stories, I would like to hear them.

Your story is a lot better than mine and thats a nice cannon to start with.
My story started when I was 13. Staying up late and browsing the net looking for a simple homemade weapon. I happened upon a crap site that sold plans for weapons, I thought nah screw this then I saw a thing called a tennis ball cannon. I was hooked. My first cannon was so ghetto it wasnt funny. It was a maccas cup taped to some toilet rolls with a coke can acting as the chamber. Needless to say this was the first thing to shrapnel on me :lol: Fun but I like your cannon man.

Thanks for the memories :P

Yeah spud, your story is...nice to put simply, with no one getting hurt.

My first combustion i used propane, couldn't get it to light(3 minutes was a bit much of having the valve open), so i opened it and looked in to make sure the bbq lighter was working, and whoosh! I was engulfed in a giant fire ball, lost most of my hair and all of my eyebrows, and burned the ceiling of my garage. Of course i was hooked from then on out.

I heard by brother discussing one to friends that he saw a few adults with. I read up about it, my brother thought it was impossbile for us to make one, And after a hundred bucks and a few weeks of research as I soon found out our pipe and fittings differences I had a very basic combustion cannon. I was hooked, always wanting to improve. My grandad was very impressed as he thought it wouldn't work. They are very rare in New Zealand, I would be the only one in my school with one, or anyone who even knows how to build one. Not many have heard of them. Thats the good thing about them here, everyone thinks they're super hard to make. :P

Interestingly enough, I got hooked through the pneumatic cannon, not the combustion. I was watching the discovery channel a couple years ago and they mentioned the use of air cannons to shoot...something. Anyway, they showed a clip of it firing and I instantly thought "I want one." Nearly stumbling over an armchair, I ran to the computer and began to research air cannons. I failed to convince my parents to allow me to build one (my dad seems to like having good written plans first). However, this year, we had a big science project in which we had to teach the class about something of your choice. Upon hearing the word anything, I thought "excuse for air cannon construction". So that's my story. It may mot be a combustion cannon one, but I've never built one. :lol:

Hehe I had the same moment this year as well. Im experimenting with a "Model Combustion Engine" to see if I can improve "Fuel Efficiency" aka what would chuck a spud the best. Ironically this will be my first proper combustion. :roll:

A very long time ago (12 maybe?), I used to launch milk jugs like rockets by filling them with propane. It was fun for a while, but the 4th of july came around and I got side-tracked with fireworks. When I was 14 I made a squirtgun out of a 2 liter, a ball valve, and some pipe/hose. I made it to take to bandcamp my freshman year.
After screwing around for a while after practice, I found that by adding a short lenght of pipe to the end, I could launch small objects fairly fast. We ended up shooting john hooker(no really, that's his name) in the back with a bunch of tic-tacs. They left welts, and everyone thought I was brilliant :? .

The next year I had improved upon my gadgets, making a new pneumatic with a 1.5x30" barrel and a 2 liter for a chamber. I taped the old squirt gun to it as well and took it back to camp with me.
That year the backs of the cabins were mysteriously plastered with shaving cream and ketchup.
I got to shoot my band director with a barrel full of water, to which he said "that thing's awesome!" :lol:

After that year I cant really remember a whole lot. I made a flamethrower when I was 15 among other misc things. I started to make things out of steel after making a forge in my backyard.
Back in february I made my first combustion (a mini) when I found spudfiles.
I made the hybrid for the competition afterwards, and only a couple weeks ago made a full-sized combustion, which I will post eventually.

I have several other guns in the works and tons of ideas, but most probably wont happen until I get a job (hopefully that will be soon).

About 2 years ago, i took apart and old nerf gun to see how they worked and i used those parts to make a 2l bottle launcher. My parents thought i was smart so i got to keep on spudding till this day.
pyromaniac and I also made a sweet dartgun with a bottle and the nerf valve. thats how we started working together.

I had been making minis for years, and i always got bored with them after about a day. one day last year i was browsing the intarwebz and i came across spudfiles and spudtech. soon afterward i made my first combustion, then burned off an eyebrow. i decided that i didnt like combustions anymore. about a month later i made my first pnuematic cannon. since then ive been a pnuematic man, but ive been a bit short on cash, so ive only built 4 cannons, but i plan to working all summer and go on a binge. hybrid, piston valve, QEV....and a pellet gun (im going to be broke again come september. so far i can count on spending almost $1000 on cannons, rifle, iPhone....sigh)
