Just The basics on how the M57 Firing device AKA the Clacker Works (The claymore "detonator"). Alot of misinformation on it so Here is a Quick video on the subject.
Thanks for the detailed video, I was able to restore one probably better than new by replacing the two bad magnets. Just wanted it to fire commonly available electric matches for fireworks displays. I disassembled as shown in the video. I verified both original magnets were installed north up, up being the button, before removal. I purchased the minimum qty 25 part number P125BD-N52 magnets from Amazing Magnets. These are the strongest you can get (N52), and 5 stacked up on each side is the same .625 as the originals but much, much more powerful. I verified continuity on the two output posts, and reassembled. I could not feel any voltage when holding the posts while clicking, but when I connected an electric match, it popped on the first snap. I also can connect an LED and it will illuminate brightly when snapped. I have enough magnets to fix one more, leaving 5 for the refrigerator.
Thanks for the reply. You have just filled in the thing I didn't understand about the 57. I assumed the magnets were arranged the other way now it makes sense. I thought the metal bar clicking over disturbed the magnetic field of the magnets rather than what it actually does.
FLIP one of the magnets. the point of the construction is to get the magnetic field flowing through the clacking bar. if the clacking bar isn't sticking to both the top and bottom bars, it's not working. once it's flipped and touching opposite ends, the magnetic field through it is reversed and the coil creates current.
It's essentially the same kind of mechanism used in electronicly-igniting disposable lighters.... only in a more robust, and larger form. very cool stuff.
Cool, i really wonder how it works, in fact the way it works is close enough with an ordinary piezoelectic matches that we usually use, except, this one is using step up generator for produce the current. Thanks for sharing 🤙
Thank you for a video, you are the only person on the internet to reveal the internals of it. I've almost thought that M57 was classified(how such a trivial thing can be a secret, and if it is why so many people sell it on ebay). Looks like engineers who design antipersonnel mines and accessories really like that concept of striker released by ball bearings that are pushed in.
Yeah I had only ever seen a picture of one opened up. Thr same type of mechanism also is used in the super bazooka iirc and the later versions of the original one when they replaced the battery in them.
As far as a light goes, you could always try to find the tester that comes with the claymore kit. I think it's just an amber led though. Obviously there's more to the tester than just an amber led but if all you're looking for is a light, you could try an led.
Yeah, I didn't get a tester with mine unfortunately. I was going to use an LED, but I changed the original magnet with rare earth ones which jumped up the voltage enough to light up Christmas tree bulbs. I made a second video on it.
As an experiment, you should add ASMR to the title of this video and see how many extra views you get! I mean no offense by that, I think you have a very chill voice and style!
Stray03 thanks man I even asked a few electronics stores if they would work on it and they won’t even try to open it or anything. So now I feel like I’m stuck with a cool collectible piece that doesn’t even work.
Honnestly even if it did work it wouldnt be too useful. It is a 3v quick pulse making it not even have enough energy to get a christmas tree lightbulb to light up. Mine didnt come with the tester so I had to connect it to a oscilloscope to test it and she started with about 2.5v after I fixed it up a bit. Now it is just barely giving off voltage. Personally I wish I could find a 10cap blaster at a good price but even those are getting expensive. I will have to eventually find something that the m57 can ignite.
Unfortunately the magnets are messed up on it so I'll have to replace them or "reset them" then remagnetize the whole thing, before I can get any workable current from them.
So cool man! Side note, have you ever considered using any type of peletized muzzeloding powder for rocket fuel? Been thinking about it, its pre cored and some of it is nitro based. I figured you probably thought about it a one point or another.
Yeah I was thinking of trying to use it to make .22 ammo for that fancy hot air initiated .22, never ended up buying the gun so the rest went in the "lots of Ideas and no time to try them" pile. As for rocket fuel I thought a bit about it, but Im still stuck in the attempting to extrude some normal powder.
I would like to get my hands on one of these. I guess the closest I will get is getting an old bicycle generator & rig up a gear box / linear actuator for it
get a cranky style blasting machine. you could add a capacitor to a clacker to make the voltage rise higher before it discharges. it would take several clacks to charge it.
the armature should snap upwards and smack the top of the metal thing on the left when you begin to press down. thats the click you are missing. take the arm off, flip it over, reassemble.
Would probably have to get it remagnetized. Ive tried a few times with mine. Not working right. Ill let you know if I figure out how they originally did it.
Not from the US so don't quote me but I dont think there is any rules for the m57. An actual claymore may need some registration as a DD if you dont want to go to a govt run facility.
Did you ever figure out how to get the initial click to go? I have a couple M57s I stole from one of my supply chains and none of them work. Just took it apart today and put it back together and came out with the same issue.
@@Stray03 I just did that with some neodynium magnets a few minutes ago and didn't seem to work yet. I think I might have the polarities switched around on the magnets though, like where I placed them at in the plastic housing so I'll play around with them and see. Definitely should have marked their placement at first.
Not sure it is enough. Probably need a real strong magnetizing setup. Not sure though as I cooked my magnets and couldn't try on the MPI machine again.
@@Stray03 interesting. My magnets are pretty strong able to hold up to 100 pounds each. I cleaned all the metal contacts too. I'll keep trying and see what happens.
Ah, got it open. I'm not sure why, but my M57 stopped doing the 1st click after disassembling the magnets and cleaning the surfaces. I even marked them before taking it apart and put everything back exactly the same, but none of the orientations work.
Even though this has nothing to do with the Claymore the West German HAFLA-35L always interested me. The design of the round seems to be the closely guarded secret. In svc. 1976-2001. It probably would have been a good perimeter defence weapon. Not sure of the tactical role other than a simple cheap substitute for heavy & clumsy WWII era flamethrowers which were starting to go out of svc. in the seventies.
I remember reading an article on it a while ago. Personally i preferred the single use flame thrower the germans used in ww2. Here is an article on the hafla: warfor.me/ruchnyie-zazhigatelno-dyimovyie-patronyi-dm24-i-dm34/
That is another one you see very little on the details of on the internet - it has got to be a contained fougasse with a bursting disc in there of some sort. A bit scary to hold and fire I would imagine lol.
Think of the DM34 as a willy pete gun as opposed to a flame thrower and it'll make more sense. Its not a napalm dispenser, its not meant to incinerate the area. It just makes it very uncomfortable to occupy ;)
@@regularcookie4023 Claymores have C4 in them. So yeah, they're all detonated the same way with the M-57. Blasting cap placed in the explosive, connected by a long wire to the clacker.

Unfortunately no. Sometimes they show up on surplus sites, or eBay, but somewhere that has a selection no.

Great video. thank you so much for explaining the mechanism
Glad it was useful and made sense. Thanks for watching.

It's not piezoelectric but yeah, it produces electricity from hand power.
Thanks for the information!
Very interesting man very interesting. Thanks for making this video. Random but cool so thanks!
Lol I think most of my videos are pretty random. Thanks for watching.

You could try a led, no need to even place a resistor in between since the current over time is small enough.
Unfortunately the magnets are messed up on it so I'll have to replace them or "reset them" then remagnetize the whole thing, before I can get any workable current from them.

Stray03 yea it is really hard to avoid air bubbles!
yeah too much solvent and drying too quickly causes it, I cant get it right lol.
How did you remove the stuff covering the screw holes?
mine popped off when I used a flat head screwdriver on the stuff. I have a feeling mine had been heated though so maybe that is why it was easy.
I would like to get my hands on one of these. I guess the closest I will get is getting an old bicycle generator & rig up a gear box / linear actuator for it
Ebay. Problem is most are expensive. Also they dont work with rocket igniters or christmas bulbs
field telephone I guess :p
get a cranky style blasting machine. you could add a capacitor to a clacker to make the voltage rise higher before it discharges. it would take several clacks to charge it.
I've been looking for one of those twist ones actually. the plunger ones are too expensive now.
These are the same clackers used today they’ve been in service since ww2 or Korea or Vietnam not quite sure but a long time
Yup, the same mechanism is used in the superbazooka too, so when that was invented.
Stray03 ww2 then
the armature should snap upwards and smack the top of the metal thing on the left when you begin to press down. thats the click you are missing. take the arm off, flip it over, reassemble.
by arm you mean armature?
@@Stray03was that the solution?
@elivo905 no. New magnets was the solution.
I have one but it is giving out no current at all. Can you or somebody tell me the process of getting this to work again?
Would probably have to get it remagnetized. Ive tried a few times with mine. Not working right. Ill let you know if I figure out how they originally did it.
What is the connector type on the top of the clacker?
Nothing commercial that I know of. I think it is just a special made one for specific use.
Imagine pressing that and you hear a thud from far away
Video games get it Wrong. It is not a wireless set. It needs to be connected with a wire to the mine.
@@Stray03 oh...... imagine if a game did that and when you go to far from the c4 the wire connected to the detonator just snaps
Is it fully legal to own a clacker or do u have to do paper work with the ATF
Not from the US so don't quote me but I dont think there is any rules for the m57. An actual claymore may need some registration as a DD if you dont want to go to a govt run facility.
Stray03 ya ik the claymores were a dd I just didn’t know if the clacker would have been or not
Did you ever figure out how to get the initial click to go? I have a couple M57s I stole from one of my supply chains and none of them work. Just took it apart today and put it back together and came out with the same issue.
I think once you take them apart you have to re-magnetize them. I messed up my magnets so Ill have to re-set them then remagnetize the whole thing.
@@Stray03 I just did that with some neodynium magnets a few minutes ago and didn't seem to work yet.

@@Stray03 interesting. My magnets are pretty strong able to hold up to 100 pounds each. I cleaned all the metal contacts too. I'll keep trying and see what happens.
@@Stray03well I got the click back actually. I put both south poles facing up. Not getting any green flash on the tester for it though.
Any tips on how to get the housing open?
I had to cut with a razor blade carefully.
Ah, got it open. I'm not sure why, but my M57 stopped doing the 1st click after disassembling the magnets and cleaning the surfaces. I even marked them before taking it apart and put everything back exactly the same, but none of the orientations work.
wonder if there are fusion360 files of this, i would like to print one.
Probably exist. If like the mines though they are more display than exact
How many volts is it supposed to produce and can you use a 9v battery
It is supposed to make a 3v pulse each time it clicks. So 2x per squeeze and release.
Yeah a 9v will set off whatever that will.
@@Stray03 Thank you man much oppreciated

Maybe a capacitor could help

Imagine if he uses it and some random M18A1 Claymore randomly detonates ._.
You are a gamer right? M-57 isn't a wireless remote control. It is connected directly with a wire to the claymore.
@@Stray03 oh how about a c4 Tho? Thats so Super interesting

What price? And is it with the testing kit?
I almost died in 1999 playing with one
How so?
@@Stray03 mine went off but my battle buddies didn't. When I looked out the foxhole I was staring at a live claymore mine.
@simpledamon lol yeah definitely would be a puckering moment.
Just enough juice to heat up a strand or two of nichrome... Thats all it takes...
Yeah but Im really wishing I knew what was special about it. 3.5v that quick wont even heat a christmas tree bulb enough to get light out of it.
