Title: Potato guns
Post by: Monsterlover on October 30, 2008, 03:15:24 PM
It's been a long time since I played with one.  We built them professionally back in the day.  I've shot just about every object i could fit into the barrel out of one of these, had one taken away by  [leo], had one explode inside the car on a "mobile mission" and enjoyed every minute of it.

These vids are great.  These are much bigger than the guns we built. 

I love them  ;D

First, what we never did, but I can't see how. . .

did that in college.  ours would put a tater through a hallow door.  we used a coleman flint steel sparker out of a gas lantern for ignition instead of an electric grill lighter, so it was always a little iffy if it would go off or not.

We were "required" to build one for my high school physics class.

My buddy Drew and I built one out of 8" and 2" PVC irrigation pipe.

8" x 12" combustion chamber with an electric grill lighter built into the removable breech.

4' barrel of the 2" pipe with a chamfered front edge to cut the slice cleanly out of the potato.

The real stroke of genius was the 1" PVC ramrod that was the perfect length to leave the plug about 2" in front of the combustion chamber.

Firing was a 2-man operation. We got the best results by spraying a shot of starter fluid on the wall of the chamber, sealing it up, loading the barrel (and compressing the charge  [evil]) then rolling the gun a few times to get as much of the ether vaporized as possible.

Aimed over the shoulder like a bazooka that thing was "accurate" to about 100 yards.

Man, I miss high school physics.

I just saw one a buddy made.

He made two.

A traditional one at least four feet long.

He also made a potato pistol. It was less that 2 foot long and it had a tee in it for a handle and a way to put in the gas. idnited by a gas grill ignitor. It was a blast.  [evil]

Sounds nearly identical to one a friend of mine had years ago.

Another friend had an apartment on top of a store which faced main street (four lane), complete with patio to the rear. The local police station was located diagonally from his place across the four lane. One night this friend had a party. The other friend brought the potato gun. We had hours of fun launching potatoes into the (then empty) parking lot of the law enforcement center. By the time we called it quits there were tater shards everywhere in that lot. And nobody got caught.  [evil]

Imagine what I'd look like cruising the interstate on a KTM with a gigantic spud gun strapped to the side of the bike. . .

Funny enough, the British had a similar idea during the Second World War to lob molotov cocktails and liquid phosphorous bombs.

Ah yes

I had an 8' creation with a lantern lighter. It was constantly blowing the seal though...

Accurate and had range... probably 100+ yards when lobbed

Good times

I was man enough to take tater cannon on!  Lot's of  [drink] involved of course.

I'm in the helmet.

Little did I know, my "friends" filled the chamber with whipped cream in addition to the obligatory potato.
