The airsoft land mine that I bought was a pitiful waste of $50. The self proclaimed "loud boom followed by a large blast of powder" was a tiny pop and half inch high puff. Enemies didn't even notice that they triggered it. Frustrated, I built a better, more powerful mine. It's easy to replicate and simple to use. It shoots BBs twenty-eight (28) feet and powder six (6).

Step 1: Materials.

This project is fairly inexpensive, depending on the materials you already have. I only had to buy the springs.

You will need:
  • 1 inch diameter pipe.
  • 3/4 inch diameter wooden dowel.
  • 3/4 inch diameter washer.
  • 3/4 inch diameter spring (ID # C-756).
  • Screws, 1/4 inch diameter.
  • Fishing line.
  • Smaller dowel.
  • Small metal dowel.
  • Suitable safety pin wire.


<p>im a big airsofter and in making a new corse and I needed some traps and I think I just found one</p>
<p>I'm thinking of putting one on each side of the path so they get hit on both sides. I love it and I'm gonna make them.</p>
<p>I don't know how I landed here - but seeing as I did ... I suggest that you could file a generously-sized notch into the edge of each washer, big enough for the spring wire to clear. (Make the edges of the notch nice and smooth to avoid stress cracking the spring (sorry, my engineering discipline insists on being heard, LOL)). </p><p>This should facilitate the task of locating the spring reliably.</p>
Well done!!!
why don't people just have the airsoft tripmines so that they cannot step over it,or even have a fisherman with a fishing rod to angle it in and make it seem so that they cannot escape
Funny guy. No sane person would want to stand still with a fishing rod while there are people shooting at them! haha
nice vidio. i know it was all acting. and wheres the mouth peice?
Mouth piece?
ya. to protect the mouth so you dont swallow the airsoft ammo
You only really need eye protection. I wear my full faced ghillie mask, but I know people who go into the battlefield with goggles or aviators.
I happen to know a guy who would disagree very strongly with that statement. One of his front teeth got broken off at the gumline by a 500 fps sniper from 30 yards away. Its better to have something. Even if its just a bandanna tied over your mouth.
Mouthpiece really isnt needed, just eye protection, besides, i would keep my mouth shut if i was getting peppered by bbs
Great idea. <br>Will test build a version and if it works out I will mass produce them for our next Airsoft event
im gonna make 2 of these but using a confetti cannon things which operate in the same way with springs :)
it's stronger usage advised to first off use invisable fishing line, second to use camo on the trap like a ghillie suit then have a pulling handle for when playing with strong people that could snap the fishing line and to not use the drill unless you are bolting it on,this is what from what i could see happening
if your drilling a hole then why not bolt on a spring instead of screwing cuz when your screwing in if theres a hole then it's not as strong but harder to screw in
how about a more exact awnser how about measuring the compressed height of it being standing up of the mechnisim before it's secured then on the same measurement mark where the pin should be
where did you buy the spring at?
Absolutely had to try this, your design is amazing. Works like a charm.
awesome design and easy to make<br>
Sorry but thats dumb. Make something explode!!!!!!
what fps would you estimate the bbs to come out at?
probably aroun50fps
50? thats way low thats about 37 mph
If its any faster itll go to high and not hit the target
its launching more than one bb and its operated by spring but i know what ur thinking. some airsoft guns are spring powered. buuut those spring compress air to launch the bb its not forced by the spring the bb that is<br>
it doesent have to be very fast, just enough to get them out there.
my buddy and i shot each other with air soft shotty (homemade pneumatic around 120 psi.) from like 30 -40 feet. the carnage resembled a be swarm.
that was a really dangerous thing to do. you are lucky none of the ammo penetrated.
this is pretty cool, but i cant find that type of safety pin
just use any kind of wire or rod strong enough to hold back the spring
nicely done, cant beleive i didnt check out this ible more closely. i must do this.
I think your &quot;pins&quot; are pegs for a pegboard, like in a toolroom.
Let me guess, you bought the land mine from airsoft GI right?
hey nice instructable !&nbsp; how can i know what is *bb* ?? is the bomb or the ammo ??<br />
BBs are small balls shot by airsoft guns. BB stands for Ball Bearing.<br />
Actually, it doesn't. It's reffering to a size of shot originally used in shotguns...There is also &quot;B&quot; and &quot;BBB&quot; sized shot...<br><br>Wikipedia-BB guns are a type of air gun designed to shoot projectiles named BBs after the birdshot pellet of approximately the same size. These projectiles are usually spherical but can also be pointed; those are usually used for bird hunting. Modern day BB guns usually have a smoothbore barrel, with a bore diameter and caliber of 0.177 inches (4.5 mm). BB for modern day BB guns are usually steel, plated either with zinc or copper to resist corrosion, and measure 0.171 to 0.173 inches (4.34 mm to 4.39 mm) in diameter. Some manufacturers also still make lead balls of slightly larger diameter and which are generally intended for use in rifled BB gun barrels, as were formerly used in BB guns.<br><br>(Found under the BB gun entry)<br>
Thanks SparTa ! :)<br />
Is it a multiple use mine?
I got to say it worked pretty good but I made mine out of metal tubing and a screw in cap so If anything breaks I can open it easy to fix it I also have a second ca so that If I prepare them (I made a few :P) before a game All I have to do is remove the top cap and if it went of by accident I dont get hit :P
I've seen that M4 somewhere before... I think it was at Fry's. It was $79.99, if I have the right gun. Just saying.
That gun was a terrible waste of $80. <em>Stunt Studios SS2.</em> It's cumbersome and broken. The &quot;grenade launcher&quot; (which turned out to be a pump action, shooting one lousy BB at a time. Not the Co2 shell loaded one I was expecting.) jammed. The gun itself tends to quit on you at the least convenient times (smack dab in the middle of a firefight, for example.). Now I just use my trusty Co2 pistol (which is starting to act up :(.)<br/>
i bought a aftermath kraken (cyma 0.28 rebrand) and ive had it for a month now and it works like a dream
Yeah, I like my Cyma 028 (I think that's the right model... AK47 is what mine is) anyway, I got it for 100 bucks and it works great.
I have the same gun as both of you. i got it from big 5 and have had it for three years now. it amazes because it still works perfect and it outshoots my 200 dollar m4 variant sniper
is that suposed to be a pokemon icon i_am_ninja?
about the fourth pic it is safe cuz da saves on<br>
Hey i did this yesterday and it turned out awesome! Thank you.
