Been wanting to try this for a while.
As a bit of a fun challenge for myself, I decided to construct a powerful, fully functional combustion powered rifle using nothing but what I could find in the trash.
I'm not going to go much into detail over this, as this is more of an experiment than a tutorial. More pictures, less words.
Plus a video:
1st step: Acquire trash
You'd think this was the easy part. I thought it would be.
But then I opened the lid.
"HOLY MOTHER OF ALL--------"
That was a BAD idea.
And, well, I'll leave it at that. I managed to find everything I needed.
Ignition System: (broken lighter) check
Extra stuff: (for looks) check
^ feels funny saying 'for looks' when building a gun out of trash.........
There were three candidates for the combustion chamber. A soda bottle (mist twist lemon lime flavored, what else?), a Gatorade bottle, and a dishwasher detergent container. All were fairly promising, but before settling on any of them, I needed to find out how resistant to heat they were.
You don't want a combustion chamber that melts.
This is fairly simple. I filled them with flammable gas (in this case propane), and lit them off.
The Gatorade bottle and dishwasher detergent held up beautifully. No deformation. The Mist Twist Lemon Lime (flavored soda) on the other hand couldn't hold up to the heat, and the plastic deformed on the first shot.
So the fight was between the Gatorade and the Dishwasher Soap. Both would work, but I decided on the dishwasher soap container, as it was larger. I was going for a rifle, not a pistol or carbine.
Time to dismantle the lighter. Unscrew a couple screws, slide off the funny black piece at the bottom of the barrel, and it should pop right in half.
See the wires coming from that small rectangular shaped thing with a button on one end? That is the sparker assembly. You can discard everything else. (Unless you want to make a mini flamethrower with the fuel tank, that is)
Figuring out where everythings gonna go, making sure it will look good, and all that.
Cutting the hole in the combustion chamber for the barrel. Fairly obvious.
The barrel must go into the combustion chamber. Thus, we need a barrel-sized hole.
Drill/cut out hole.
Now I'll have to admit, I am cheating a little. The whole shebang will be held together with duct tape (greatest invention of mankind).
But is that really cheating? I mean, you could find duct tape in the trash..........
The construction of Ugly is now finished. Trouble is, there are gaps where the barrel enters the combustion chamber. Not good. We don't need flames shooting out and roasting poor Jake's fingers.
Not to mention the gun wouldn't fire because of loss of pressure.
I filled the gaps with hot glue, and then duct taped all around the joint for extra strength. Hopefully it will be strong enough to hold under the pressure.
Now for the fun part: Testing the contraption.
As you can see, this is one of those few times I thought it necessary to put on some safety gear. Trash, after all, is not meant to hold any kind of pressure, so I wasn't sure the gun wouldn't come apart on me.
I'll say, it's a pretty intimidating moment; that first shot. I wasn't quite sure what would happen.
But what do you know, it actually held together!
It fired the darts very well, going through my dartboard and pinning it to the wall. Also penetrated about 1/2" through plywood. Decently powerful.
Wow. I just built a deadly dart firing gun out of trash.
That's pretty cool.
Now I don't exactly recommend you attempt this, the parts used were not designed to take ANY kind of pressure, and there's a fairly high chance that something will give, in which case there will be a high speed outflow of very hot gas within rather uncomfortable parameters to your personal self. Attempt at your own risk.
This thing is absolutely mental. Quite possibly the most frightening thing to shoot I have yet constructed. Well, not quite. The Football Mortar takes the cake. (that thing was NUTS) But this is a good second.
It is scary.
And impossible to aim. But heck, its made of trash!! For what it is, i'd say this was an overwhelming success. And a good addition to my rapidly growing arsenal of homemade weapons. (looks great on the wall)
And I doubt many other people could say they've made a gun out of trash..............
