How to Build an Airsoft Trip Mine.

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.

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

[35Timmy]

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

[35Timmy]

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

[35Timmy]

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

[35Timmy]

where did you buy the spring at?

[Burnsides]

Absolutely had to try this, your design is amazing. Works like a charm.

[tpatten]

awesome design and easy to make

[Aron313]

Sorry but thats dumb. Make something explode!!!!!!

[pyro man]

what fps would you estimate the bbs to come out at?

[rssdeltaforce64]

probably aroun50fps

[daetol]

50? thats way low thats about 37 mph

[KnexFreak360]

If its any faster itll go to high and not hit the target

[kve23]

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

[ilpug]

it doesent have to be very fast, just enough to get them out there.

[pirate of doom]

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.

[ilpug]

that was a really dangerous thing to do. you are lucky none of the ammo penetrated.

[UNKN()WN]

this is pretty cool, but i cant find that type of safety pin

[ilpug]

just use any kind of wire or rod strong enough to hold back the spring

[ilpug]

nicely done, cant beleive i didnt check out this ible more closely. i must do this.

[airsoftmaster191]

nice vidio. i know it was all acting. and wheres the mouth peice?

[Spl1nt3rC3ll]

Mouth piece?

[airsoftmaster191]

ya. to protect the mouth so you dont swallow the airsoft ammo

[UNKN()WN]

Mouthpiece really isnt needed, just eye protection, besides, i would keep my mouth shut if i was getting peppered by bbs

[Spl1nt3rC3ll]

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.

[mechaninja]

I think your "pins" are pegs for a pegboard, like in a toolroom.

[master mad]

Let me guess, you bought the land mine from airsoft GI right?

[yusuf786]

hey nice instructable !  how can i know what is *bb* ?? is the bomb or the ammo ??

[1spartan95]

BBs are small balls shot by airsoft guns. BB stands for Ball Bearing.

[Fire Explorer 3]

Actually, it doesn't. It's reffering to a size of shot originally used in shotguns...There is also "B" and "BBB" sized shot...

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.

Thanks SparTa ! :)

[BlackOps123]

Is it a multiple use mine?

[Bam2169]

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

[kve23]

about the fourth pic it is safe cuz da saves on

[TALLJ29]

Hey i did this yesterday and it turned out awesome! Thank you.

[Kruegem]

it beatiful "sniffs'

[Robot Lover]

this is great but I think that this should have a 45 degree angle at the top so it shoots directly ay them. 4 1/2 stars!

[kicker109]

would this work with flour instead?

[yourworstnightmare]

this is the best tripwire on instructables! simple, clearly explained, and the end product is amazing.Mind if i display these at my airsoft site? You are amazing! to come up with something like this

[mechaninja]

what is ur airsofting site?!! plz tell me! (begs)

[yourworstnightmare]

i told everybody there were now booby traps all over the site. i set up 25 of these things all over and it really aded to the game it made people go different places thanks a ton!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
