BB Machine Gun.

[S.S.]

Made one with a gravity fed hopper and a smoothbore barrel! Hooked it up to the compressor in my brothers paint booth and watch out. It will go through 500 BB's in no time flat. Not super powerful but it will imbed BB's into a piece of 3/4 in. plywood at about 50 feet. the finished model will work off of a 20 Oz. nitrogen tank from a paintball gun. My Idea is to somehow hook it to the Motion sensor on the corner of the house by the garbage cans! That should keep the coons and stray dogs from turning them over again.
My wife Keeps thinking I will grow up some day but I am resisting
for as long as I can! I love tinkering with this kind of stuff..

Bad idea to say the least. Hooking the trigger of any kind of gun to a motion sensor so that it goes off anytime something or someone passes by constitutes a lethal booby trap. If some poor garbage man or kid thats just passing through gets blasted, guess who goes to jail? Even if its the neighbors pet dog, you are still looking at jail time. What if one of your family were to approach your house and your little surprise wasn't turned off, or worse yet what if you forgot to turn it off and got a taste of it yourself?

I agree that booby trap guns are a bad idea. You will come to a lot of grief if you do it. I would recommend an electric fence charger hooked to a wire around the cans. It worked on all my dogs. You will have to set it up differently for plastic trash cans or metal ones.

I had a freon powered BB machine gun years ago. You would put an 88 cent can of freon 12 on it and it would spew out a stream of BBs until the can got cold. It worked even better when I made an adapter for an air hose to power it. It looked like a golden rainbow with all the BBs in the air. They didn't have much power though. It would be dangerous to be hit with it, but it wouldn't stick into plywood IIRC.  It would punch through a cardboard box.  :roll:

Your wife will probably be the first one hit.......then what?

It is in an area of wooden privacy fence, and I am the garbage man.
We have no children and none live close to us.
I live way out in the country, My drive way is 1100 ft long off of the single lane road I live off of so there is not really as much danger as it sounds like. Besides, it only can shoot one spot, It has no type of traverse on it.
Although being a smoothbore that is deliberately left loose on the mount, it does throw about a 1 foot spread on the base of the tree it is aimed at. That tree is where the Opossums and coons come down.
This is one of those kind of things that was done just to see if it will work.
It works pretty well so far. I have another one sold already  being used in the Hay-loft of a barn for pest control. It is aimed across the floor about an inch off the ground and shoots directly into a Hanging rubber Mudflap from a Semi-Truck about 10 feet away. The safety is two light switches side by side with a bar between them. One is upside down and turns on the power to the motion sensor when the lights are off, flipping the lights on turns the power off to the motion sensor. It will chew a barn rat up pretty good. The guy that wanted it absolutely will not put out rat poison because of a problem with some Horses in the past. He wants another one for under the floor of his chicken house also. This Idea may sound crazy, but I have already found that there may be a small market for them. My main problem so far is rate of fire, it needs to be much, much slower. I'll work it out.

Worked out very well except for the rate of fire.
I never figured out how to regulate this without
loosing velocity.
