- Description of the fuze used in the "Bouncing Betty". In this video I show how it works, Dry fire, Live fire, and then explain some of the things I needed to do to partially restore her to working condition. Hope you enjoy it. The live fire is partially off screen (in my excitement sorry) I will try to make a Video of it firing when completely restored.

My first thought was the germans really like the roller locking machanism. Their small arms designs during and after the war are known to use rollers to lock the firing chamber breach, and they are pretty much the only one doing it.
Also I've seen this roller design elsewhere. Mr. BulletFeeder makes a bullet feeding die with rollers normally pushed in to hold the bullet in place. But when a cartridge case pushes the roller carrier up, the rollers are allowed to move out of the way and the bullet will be dropped onto the case mouth. It's a really ingenious design.
it sounds weird, but the kick starter lever from my Yamaha Banshee ATV also has a similar mechanism inside. a steel BB pushes against a spring, when the kick starter is pivoted either out or in. this way, the lever will not rattle around and keeps it in place, when the kick starter is no longer needed.
RR is the maker mark which stands for Richard Rinker. And yes, 1937 is the year of manufacture. I'm glad you are enjoying the fuze.
Fancy meeting you here. Thanks, I am having an issue figuring out the codes on them, I was able to find codes when trying to figure my field binocs out but I can't find a list of the ones on these. My DZ is a "dwx" and apart from seeing pics of others with that marking it appears my search-fu is failing me.
I use this very design to make pop up paintball mines back in my 20s . It was so cool to see a mine pop out of the ground & unleash 100 paintballs on someone ..... SUCKS TO BE YOU ON THAT DAY .
Please teach me how to make it, that would be so cool
Beautiful example and expertly shown. Thank you for your skill and time. Love your channel......
Curious if you had any videos on the M605 fuse, used in the M16 landmine?
Not yet. Been meaning to make one. Unfortunately not much that can be taken apart on them.
@@Stray03 Dang haha ok. It’s really hard to find any information on them, besides the cutaways of the M16 mine online 😩
For your channel's sake either have at least 6 strong coffees or a line of speed anything to make you sound awake I keep expecting zzzzs to start floating across the screen, the subject of the videos are brilliant
Or pretend one is enjoying what they do rather than sound like they're bored out their tree and waiting to go home
Why would I pretend. I dont get all emotional over crap. Im showing you how the thing works. Im not here for views im here to make a video on how they work. If i wanted to make videos to get lots of views Id make bs vids like " how many bowling balls can this supa awesome 50 cal go through or other idiot friendly videos.
You don't need to be emotional but when your sounding like your about to nod off, it makes the content that much more boring, and if you don't do this for views, then why bother at all
Putting the information online in video format for people looking for information and not for views from people who think it is a magic device that uber kills your enemies in battlefield 5
@@MarkSmith-to7xi Not everyone is addicted to that kind or format or to point scoring, with an attention span shorter than an S mine. These uploads are concise and fully informative. With the poster taking the time to actually reply and help. You want more...... ?
The paper or cardboard ring you spoke of is made of a compressed fiber material. Many countries used it in that era in various small arms but this is the only scenario that I have seen one used in an explosive device. The Germans never did anything by half measures lol.
I am a metal detectorists and one time i found a s.mi.z 35 mine in the sand at a old ww2 military base it was but it was corroded and i found at the same place a artillery round not exploded so that was fun.
I'm jealous, I've always wanted to look for that kind of stuff.
Stray03 it is really fun it is a fun but sometimes dangerous i have found a fishhook in the ground but that is really the main fear you can have in this hobby and love the video man
Yeah I have a video of a few things I found metal detecting around an old farm house, Unfortunately not very cool, but dating from 1920s about so it is still interesting.
It crazy that there are still mines like this waiting th be stepped on in parts of the world
Watch your step 🙂
I think these mines are corroded away the last 70 years. You should watch out for glass-mines. There's an old minefield in the Eifel, near Hürtgenwald.
Don't know if you have seen it, but there's videos of intact trench positions and minen fields on youtube. Uploaded by russians btw, so... don't know if we'll be getting many uploads like those in the future.
I don't think there's any best bet what to do once you step on it. If it's not the shrapnel, then it's overpressure of the actual blast. So, if possible, two things can save: distance, and cover.
4seconds of running like hell........
Hi Stray, I just saw the vid and the other ones about fuzes aswell. I am just curios how you were able to remove the three sprongs from the body. I also own one example but I am not sure how to remove them because they are in the same situation then yours were. Would be nice if you could answer me if you are still on TH-cam.
Once that screw comes off with the washers the wires should come out easily enough unless there is corrosion and then it is just to dip it in a penetrant and hope they come out in one piece.
This was very informative.
Found One of These Last Week 5 min from my house in the ground (with minelab e-trac)
Hey! Do you know what the mounting thread pitch is for these?
Don't know. If I remember tonight I'll check it.
@@Stray03 Thank you
Looks like metric 1.5
Man. That's a pretty complicated mine, all considered. But all it takes is one guy to step on it and there goes the whole platoon.
Does anyone know if when these fuses were manufactured, were they machined and then assembled by hand? It would seem to be a tedious assembly process.
I can't be sure but it seems that they are. The factories had equipment (jigs and tools) to help with assembly so I doubt they had as much trouble as me when assembling them.
@@Stray03 Wow, that would seem to be quite the long day at the plant for some German labourer. Thank you for reply.
@publius09 wouldn't be out of the ordinary for unskilled laborer jobs even today. By the time the war started I'm guessing prisoners did the task.
In your Piat 425 piece, you used a 3D printed model for demonstration. I imagine 3D printers could replace machining of parts, thus reducing labor and costs?
For certain parts yes even some can be completely made with 3d printing. Even using stampings made the fuzes easier and cheaper to make. Most of the german fuzes from the 40s are simple compared to the 35 models.
So the spikes are essentially only for show and not for any technical reason....
They are "extensions" to it. So they provide a surface to step on that allows you to place the mine deeper. Larger surface also so increases chances of stepping on it.
Clever
How did you get the striker and striker spring to come out if they were stuck in place?
I have tried everything but have been unsuccessful
I found one of the retaining balls are also stuck. Can you also send me the measurements of the springs as several are shot and need to be replaced.
I let them sit in penetrating oil for a long while then pulled them out carefully.
Stray03 any particular penetrating oil or just use wd40?
A real one. Wd40 is a catch all product originally made to displace water from electrical boxes iirc. I use products designed for loosening bolts or t40 car rust proofing oil. May have some success using an evapo rust type product but I have never used it for that purpose so no clue if it will work.
Interesting
This is all well and good, but what about firing it by the prongs? It doesn't seem all that sensitive. Something's missing here.
The prongs are fixed to the piece that moves they are just an extension of that piece. and it is a 14lb fuze.
where can i fined one like that . there aint o hole lot of places down her to buy stuff any more .
Mostly it comes in from russia/ex soviet countries / europe, occasionally you find them in north america, but rare.
Can you send my the dimension? Building a demo on CAD for a project.
How did you get the modern shotgun primers to fit?
And can you give me the spring measurements??
They are cci 157 primers. Don't know if anyone makes them anymore. I'll try to get you the sizes of spring when I get home.
About .550 length. About .040 wire diameter. 3 spiral turns and one finishing turn on either side of spring. Outer diameter of spring about .520. .400 is diameter of center piece the spring wraps around.
Stray03 thank you and by chance do you have the dimensions of the striker spring? Have two that are about done.
When I take it apart next time I'll measure
Is there a web site where I can buy one or no ?
Sometimes ebay, But usually no, there are a couple, but most come from private collectors, selling on forums.
how did u get the crimp guard off
Crimp guard?
@@Stray03 the crip that held the primer in how did u get ur out,
When you knock the primer out then just tap it with a punch to reform or remove it.
@@Stray03 ok thanks for tip
I love German engineering, so ingenious.
Back in those days... today we can't even program an proper Corona-App :-(
I always wonder, why brits and americans are so fascinated about german WW2 tech?!? X-)
Ask the space program.
Hi Stray03, I have a question and I hope you're still on this yt channel since it has been 6 years. The only thing I don't understand is how the 2 ball bearings holding back the plunger stay in place when assembling. What is keeping them from falling into the tube that holds the plunger before the plunger is in place? I hope I explaned clear enough haha. Have a great day love your video!
While installing it, not much, if you are not careful they will fall out. Using something like petroleum jelly may help hold them in place until armed though, if you need it.
@@Stray03 Thanks that explais a lot. I was wondering like really how do they just sit in there like a good dog waiting for the plunger haha. Thanks for the quick reply! You got another sub ;)
Thanks for the sub. I have other fuze videos on here along with a few other ones you may find interesting.
@@Stray03 love it! I will definately check them out.
@@stanh4739 they probably had some fixture to hold the spring loaded striker at the correct height so that the rollers don't move out when assembling.
its part of the so called human civilization.
Excellent video man,i realize its 3 years old but its a great video none the less,i had a few questions about this fuze, if your still on TH-cam let me know and ill let you know what my questions are, thank you!!!
yeah I'm still alive-ish
lol, cool,thats good to hear, i have a couple of these and one of them is missing that little spring on top and the ball bearing where the safety goes in,if that safety has a little round nut of sorts what was the point of having the little spring and ball? one of my fuzes is missing one of the ball bearings that holds the plunger, do you know where i could find one and or what size they might be? Ive seen your other videos,they are awesome, so i had to ask , how did you make new sensor\antennae for your fuze? they look killer!! thank you much for your time!!
To give some positive pressure so that it doesn't fall out or get pulled out before you are ready to pull it out. You could tie a string to these and pull it from a distance to put some distance between you and a mine in case the fuze failed somehow. Having that detent ball keeps you from accidentally pulling the safety pin out just by holding the string as you walk away from the mine.
I made the prongs with the stiffening wire from a material duct tube of sorts (the wire was already spring steel so it was stiff and flexible). Was about right so I sanded it down, got the bends about right then for the hell of it put it into homemade parkerizing solution. Turned out nice so I kept it like that.
Cool,i made some the other day from some welding rod or something related to welding our welding guy gave me at my work,its not as stiff as the original but its plenty stiff,it doesn't look half bad, those whiskers look like heck after being outside for years and years, i might mess with something different but for now it looks good,i appreciate your input and i like your videos, i subscribed.
As for finding a new ball and spring, you may be able to use a spring from a disposable lighter or pen and the bearing probably from either those cheap pinball toys the dollar stores used to sell as party favors, or maybe from a bearing (maybe in a harddrive?) Thanks for the sub.Technically if the whiskers work for one use then they did their job, and unless you are planning on using it as some sort of re-enactment mine That will be stepped on they don't have to be spring steel, Glad you found a way to "Complete" the mine does your's work? These things are made so well, sometimes I have a hard time getting around the fact that they were built to be destroyed lol.
I need one for my collection.
set it place it upside down on scales fire it see the braking point
just a thought
yeah it can be done that way but I don't have a scale that goes that high, Next time I am able to find a bathroom scale I'll get the measurement.
The Swiss disarming the Germans...huh...
*Now fill it with black powder bury it and throw something at it. What's the purpose of the 3 prongs and the little spring in top? I always thought that was some type of hair trigger mechanism that would press down on the thing with the balls* Is it just to make more surface / contact area when you step on it? An evil device I'm sure 10's of thousands wish wasn't invented.
Yeah they are just whiskers/extensions. The spring in the top part under the screw pushes down on a little ball to make sure the safety doesnt fall out until you pull it out.
I’ll have to replace that....lmao
Dude you need coffee!!!!!!
