This claymore is really inexpensive and not too complicated to build and will launch up to 50 BB's almost 30 feet. A real game changer in the world of airsoft.

Step 1: Materials

You will need the following materials for this project:
1. Mousetrap
2. 1 large nail(appr. 2 in.)
3. 1 Medium Brad(1.5in.)
4. 2 small nails(1in.)
5. 10 in. 2-by-4
6. coathanger or similar wire
7. Duct tape
8. String
And the following tools:
1. Vise
2. Hammer
3. Pliers
4. Needle-nosed pliers
5. Wire cutters
6. Drill and bits
Now you're ready to build!!

Step 2: Demolition

In order to use the mousetrap to its full potential, we must take off everything we don't need. Start with the trigger plate. Pry it off with the pliers and discard. Then take off the long arm, but keep it for later. You should end up with a stripped mousetrap and a bar.

Step 3: Building the Base

Now we're ready to secure the mousetrap to its base. First drill holes slightly smaller than the small nails in two places so the wood doesn't split.(don't skip this, I split a mousetrap when I didn't do it). 1. On the mouses head. 2. On the other side so it's a mirror image. Then put the mousetrap on your 2x4 about 1 in. from one side and nail it in.

Step 4: Super Staples!!

Now take your large nail, cut off its head, bend it 90* at the first third, and bend it again at the second third. You should now have a giant staple.

Step 5: Raising the Bar

Now it's time to build what will hold the mousetrap(claymore) from triggering. Take your bar from step 2 and enlarge the hole on one side with the needle-nose pliers. Then slip it on the super staple, making sure it can slide easily. Next drill 2 shallow holes next to the mopusetrap on the "Victor" side next to the "R". Drill the holes as far apart as the super staples' legs are so it will fit in the holes with the bar. Nail it in so that there is a 1/4 in. gap from the staple to the top of the mousetrap. 

Step 6: Setting the Trap

Next we're going to put a nail to hold the bar down. Take your medium sized brad and nail it half way in on the "Victor" side next to the "V"  parallel to the other nail. Then bend the brad slightly less than 90* away from the "V". You now should now be able to pull back the swing arm and put the bar across and under the nail to set the claymore.

Step 7: Extensions

Take your piece of coathanger and make a model of the swingarm on the mousetrap. T ake a strip of duct tape and tightly wrap the extension to the swingarm making sure it can hold the force of the mousetrap. Now take a piece of tape twice as wide as the swingarm and make a panel with it by sticking it to the arm and itself.

Step 8: Center Pocket

Now make a pocket out of duct tape to hold the BB's. It doesn't have to be fancy, just as long as it does the job. Next, tie a string to the bar across the swing arm to be the tripwire. It might take some adjusting to make the pull of the string less, so if you need to, just adjust the bent nail to a different angle to change the trigger pull.

Step 9: Conclusion

Well, that's it. As you can see it's not too complicated and is easy to make. I have made three of them so I can set them around my base and not have to waste my battery or ammo. In that sense I might as well just sit around with a soda daring people to get me. But it really is a great and inexpensive claymore that works great.

Nice idea. But Sorry it is no claymore.
my finger relly hurts the trap got me
the claymore shoots bb's so eitherway you will still use ammo...
Use unpopped popcorn* or rock salt, both are cheaper alternatives where I live. I typically use corn because it's cheaper and you can buy it in large amounts.<br><br>*I know it's called corn, I just didn't want to imply canned or frozen corn.
i just love how simple and effective these are.
nice ible. i made one but i found out that it throws the bbs either forward or at the ground so i added a string thing to the arm to make it stop halfway over. it really works.
I made this and it works like a charm. But i also made a few mods.<br>1) I put an angle bracket so that when the trap's duct tape box slams down, the trap swing arm hits it so no ruined duct tape box.<br>2) I used a regular staple instead of a big nail for that part.<br>3) When using, make sure that the trip wire is at the end of the cross arm thing and that the cross arm metal thing is just at the lip of the bent nail. Sadly it takes a lot of force to pull out, so make that part as fragile as possible.<br><br>Other wise, i love it. Pics will be posted later.<br>:D
Thanks for the feedback. At the time I'm working on one with a rat trap and making it motion sensored, so I might work some more improvements into it. Also, try putting some long nails in it so it will stay in the ground, It works a lot better when you do.
You definitely need to post a video of this, it is way to great to not see in action!
true dat!
Did you just copy me?
No. Yours is much simpler as it is just a mousetrap with a box and a string holding the bar back from swinging all the way, easy and very fast to make. Mine has the bar perpendicular to the rest of the claymore while yours is parallel to the claymore. The ideas are similar but different too. When I saw yours I knew it would work just as well, but I just like things more complicated than they have to be.
