Old Magneto for Phone calls - Restoration
ฝัง
- เผยแพร่เมื่อ 1 ต.ค. 2024
- This is a very old generator "magneto" for phone calls.This is my moost expensive restoration, it cost me 40 euro.
A telephone magneto is a hand-cranked electrical generator that uses permanent magnets to produce alternating current from the rotating armature.In early telegraphy magnnetos were used to power instruments, while in telephony they were used to generate electrical current to drive electromechanical ringer in telephone sets and on operaor consoles.
I hope you like it this restoration, if you want to send me someting to restore please let me know!

Thank you my friend. 👍👏🥇
I am currently watching your oldest to newest vids. While watching this one, I asked myself "How does this allow someone to complete a call." Thanks to you I am now learning how the whole process works. It's pretty amazing.
Wait you live in France? or did you go there?
So is this an oldschool portable phone charger?
🤣🤣🤣🤣something like that
Hey man! You got a new video comming soon?
this question is for my mechanics i think 🤣
@@TysyTube Yeah and btw this is a great project, I wonder where you guys get these old school stuff
flea markets
Thanks for this. Similar units to these were still in use back when I was doing my apprenticeship in the 70s. It was part of our job to refurbish them. They were located in remote railway signal locations and used on a party line to call the signal box, railway stations or other signal locations using a call code. The units we worked on had a make/break button (press to make) and depending who you were calling depended on the (simple) code you rang out, controlling sig box was usually a long ring and other sig locations were a series of short rings.
As a (very young) kid our farm had a party line as well and our code was 1 long + 3 short (B), next farm was 1 long + 1 short + 1 long (K), over the back was R and up the road was H. Exchange was 1 long, but without the make/break button, had to do it with the handle, generally 3 turns long, 1 turn short.
Was great to see them again, brought back many great memories
Thanks & Cheers

Thanks for sharing, I was wondering about a timeframe for the use of these, I was thinking they fell fully out of use much earlier like the '50s or so, it's very cool to learn that this old tech stayed kicking in some capacity all the way up into the '70s.
Side note, I couldn't help but wonder if that "98" on the bottom might mean 1898. Probably not, it looks like some sort of manufacture or inspection code, but it's still a neat thought.
The signalbox DC autophones were an easier bet! No frantic winding, just press the code on one of four buttons (IIRC, red, black, green or white. Remember them? Our local 'box was two short presses on black). Incidentally, I worked in a shop in 73 that had 2 branches 1/4 mile apart, and we had a direct line between the two worked by these.
don't let your knowledge be lost please. transfer it down to younger generations.
In the 1990s, there were still party lines in use in at least one area of Pennsylvania, although I can't say for sure what the equipment looked like. The stragglers didn't want to give up the shared lines!
@@Jennsylvania hehh... for "stragglers" read "gossips".

I love how the magnets in this thing look exactly like Wile E. Coyote cartoons taught me magnets look like.

Cool!
thank you so much 😊, i am your fan😍
Fan of both of you
So, did you get through? or is the caller unavailable?
i'm a teeny bit disappointing that you didn't try and remagnetize the 3 big magnets. The thing is so old, it probably could use it, and it'd make it a more powerful magneto.
wondering the same thing.
The charge is gone in an instant either way. Be fun to play with capacitors on the output like some have suggested. Just for some old school electrical fun.
@@amicklich6729 i don”t think it is a magnet, it is just an iron core.
@@mixtrooo The curved bars are permanent magnets.
How or What is the best way to re-charge an old magnet? is there a simple/easy way to do it home? Asking because I found an old 2-stroke engine with flywheel magneto and the magnet don't feel that strong.
When I watch these restoration videos it makes me think if 50 years from now they will be restoring Roombas...
Me: No way he can restore this
TysyTube: Hold my 🔧
13:30 magnets must be repelled. there must be three identical poles in a row
Ideally, you should remagnetize those magnets.... or find a neodymium one to substitute those... then you can make it a emergency cellphone charger
What to do:? hook it up in your house, the other to a bell/ring in your workshop. When your significant other needs you to come from the workshop, they 'dial' this box, and you hear a ring! (come and get dinner!!!)
Did you verify the poles of the magnets before repainting the black ends? I believe the black ends identified one of the poles (North or South), the end not painted black the other pole. If you mix them up the magnets will cause bucking currents within the coils and reduce your voltage and power output.
just think, I have a working TA-312 army field phone that has a tiny version of this inside its shell. Its old and will still knock the &^%$ out of a person holding the wires. I bet this thing could pulse a phone 20 miles away, so if its a novelty it can still rock you given the size of the magnets
He didn't. At around the 13 minute mark you see the three magnets were stuck together, which means the middle one was marked with the opposite polarity to the outside ones.
isodoublet was just coming to say the same thing.
The three magnets were stuck together so one of them is painted differently than the other two.
:(
That’s disappointing. It was going so well.
Well at least it's not as bad as the guy who dunked a whole electric motor in nitric acid.
He should hook up a multimeter to it and test the output voltage. Even a small magneto like that should generate at least 70 volts with enough current to light up a small, low-wattage incandescent light bulb. Actually, you have to be kind of careful playing around with magnetos because they can give you a nasty little shock!
15:55 i thought he was finna do a few lines of wood dust to keep himself going
Gaaaah!!!
Always sand WITH the fibers on wood... My god, I almost fell of my chair when you started go wild with that P120 grit paper...
And the varnish job should be thicker and buffed with a cotton filled cloth with some acetone drops in order to to shine like the old polish 😊
As someone who is wreckless I wanna purposely not sand with the fibers on wood, but as the daughter of a woodworker the thought of doing that physical hurts
Queria saber, como é que ele lembra como montar tudo depois? 🤔
Incrível! Amo ver seus vídeos.
If he forgets how to put something together, he has the video of how he took it apart. (I hope that answers what you asked, I don't fully trust translate)
08:08 I'm pulling my hair out and running screaming into the night because I know I'll never be able to put it back together.
i really like the way you respect the antiques while restoring them. the way you give them a home where they are safe is great too.keep up the good work :)
One magnet is turned the wrong way
Yep, it only runs ai 1/3 power now because of that.
@@galvanaut7119 the same reason why it's easier to spin
I'm glad I'm not the only one that noticed that
@@blackturbine Ah yes, Lenz's law!
some pretty smart comments for youtube XD it's been a while since i was able to read something based entirely on physics that i agree with and i fully understand the principles behind but not the actual laws at hand, AKA i learned something without needing to learn a bunch of support material, and that is always the best isn't it?
It’s correct, the other two are reversed.
Lots of work to make it beautiful. To avoid damaging the insulating laquer on coiled copper wires, they sell an electric motor cleaning spray, but the best way is dusting and dry paint brush, with mild soapy water if neccesary to clean grease. Many solvent sprays will eat the clear coat protection on the coils, especially old ones. Cool video. I'm subscribing!
2:00 two hours later: “ok, now i am curious if international space station will work with this...”
this would be so impractical to have nowadays but goddamn do i want this thing, it looks so cool
Actually NO It's Not Impractical At All! They Make Great Hand Crank Generators For Numerous DIYs! From Socking Fish, Charging Li-Ion/Li-Po Batteries & Super-Caps, +++, Watch My New Channel & I'll Be Posting Some Videos Soon... LOL
*Emergency radio.*
Emergency Lights!!! LOL
I don't think it's impractical. If you watch the old movies, you can see, that all it took was about one seconds of twisting that thing, for making a call. The rest had to be done by the operator. And it's more environmentally friendly. Image all the applications that Grumpy John listed, plus even more he didn't write down, used by billions of people world wide - that would save the need for some nuclear plants. Also it has the big bonus, of being independent, in case of power failures, that's especially important for making emergency calls. With today's IP based telephony, the non availability of emergency calls leads to an increasing number of casualities. There are already statistics about this problem. The whole IP infrastructure is notoriously unreliable, and using this for emergency situations is like setting a fox to keep the geese.
Telephone magnetos can generate up to 100 volts, or even more with bigger 5-bar ones. And you don't even have to crank it that fast. Not only are they a cool display as an antique, but I can definitely think of a lot of practical uses! Hook up a small gas engine to it (like maybe even a weed eater engine) and you have a very light, portable emergency generator. Connect a rectifier to convert the output to DC, and you can use it to recharge batteries, power a radio, etc.
I love your attention to detail. Making every part look better than when it was new. Great job.
Charge a phone with a phone magneto, sounds fitting.

No this is PATRICK!
44 screws
You cutting and lining that sawdust up like you were about to snort it😂 I was literally crying from laughter when I saw that!!😭🤣
thanks for the Scotch Brite pad under the sandpaper to remove the burrs on the screw heads to avoid flatspotting them !
I bet you use these videos to remind yourself how everything you take apart goes back together.
Fabulous restoration!!! Reminds me of a similar device I made in my high school (1968) Physics class. I went to a progressive all-girls high school at a time when it was rare for girls to take such classes. We made an a.m. radio. I very clandestinely threw a wooden thread spool with loosely wrapped copper wire out the second story classroom window, shimmied up a steel beam and secured the copper wire to the top of the bus awning for an antenna. Got 2 different stations! Thanks for the great memories!!
My Grandad had one of those. In the summer, he would stick two steel rods into the grass on our front lawn about 4 feet apart. He strung a wire lead from the magneto to each rod and I cranked away. Huge night crawlers (earthworms) would come to the surface and wiggle around like crazy. We would catch them and use them for fish bait. DO NOT get between the rods with bare feet. You'd get a nasty shock.
Crap it hurts watching you not pressing firmly on the screw and seeing the driver slip off the screw and braking the head of the screw. For the love of god buy better drivers. The bit you used for all the disassembly was way to small for the screws the thing had. All the best!
Instead of using an abrasive oil for all the small stuff you could put it in a mason jar with some grit and tumble it or just get a rock Tumblr for that matter. I hope this comment makes your job a little easier!
Send it to ElectroBoom so he can put it on his scope.
32:26 Woah! He has a display for all of the things he restores! This dude's an artist!
Use it as a BDSM Toy
There is something about fast-forwarding hammering that makes me wish I was a robot.
I'd use it as an Emergency generator for lights or a a radio. incase of a storm strong enough to knock out the power.
All of ur restorations are very good . But this isfrom one of your best restorations 👏👏👌 keep it up.
Although those gears are exposed , apply some grease to it to protect it from wearing out and also will reduce noise.
This ist a really nice restoration again,
but i was wondering if the center Magnet may be not correctly oriented. When the black paint marking is applied, the magnets stuck to each other, which should not be the case as the magnets must have equal field orientation for operation in this generator. When the magnets e.g. north poles are getting marked black, the poles should have repelled and would need to be forced to stay side by side. If they stuck together as seen in the video the orientation would be NSN or SNS. video at 13:26
@SgtPiggie *troubling. his electronics restoration is troubling.
2:20 you forgot to press the drill button
Je ne pense pas qu'un jour il ait été comme ça. Même juste après sa fabrication. Magnifique travail. La famille Postel Vinay que je connais bien serait fière de cette restauration. Bravo !
Maybe you could add to the description how many hours it took? Of put it in the screen at the end. I would really love to know!! 😊
I enjoy your videos, but I think you would do well to get a selection of various size screwdrivers which better fit the screws. In this instance, a couple of gunsmiths screwdrivers would be a good choice.
maybe some one want to sponsor me
Yes, you cannot beat old school screwdrivers I have a growing collection of old tools. But you have to make do with what you have until you find some reasonable priced ones keep a lookout at the flee market.
I can't believe you could put it back together. It would never get redone if I had to do it. I wouldn't remember where anything went back
well he DID record it
THAT"S what that is. I have an antique patent model similar - it uses wooden blocks and wound string to depict the copper windings. Really neat!
If more than 50% of an old piece's paint is intact I leave it alone.
Seeing you struggle with the flat-head screws give me a new appreciation of the Philips head screw
WOW, again. I remember one like that in class for a Electricity demo (NO, I'm not THAT old... 😁 ). 👏👏👏
thank you so much 😊
Not a good idea spraying the coil(armature) with WD-40 it could degrade the protective lacquer, or enamel on the wires!!

How do you know how the parts belong together again??? Did you make Photos before beginning?
Find a windmill to restore to turn the handle and use it to charge up torch battery.
yea good idea
just a nice job,the guy is like an artist
French resistance used them to detonate explosives during WW2
maybe because is make a good shocking current
@@TysyTube it is shocking when you hear that French had resistance:XDDDDD
Also used to torture pows for interrogation
@@flyagaric007 BS. If it wasn't for the French army the British would never have made it from Dunkirk. If it wasn't for the French resistance the landings wouldn't have been so successful. Too bad "Monty" was such an idiot.
In Russian army we get from ТА-57 (field phone) about 100V DC.
I really would have left the wood as is. Gave it character. Still a great restore! Great vid!
thank you so much 😊
I wouldn't have filed down the screws and cast pieces either, it's what gives the piece it's look .... That and as you could see it ended up exposing imperfections like air bubbles in the cast iron
I agree with the timber restore. steel wool and metho to remove only the varnish. you have removed the patina.
I agree by the time it was all sanded down and filled with wood putty might as well just made a new box if wanted to to look new. Left the old box to somebody that would only restore it.
for my taste I agree, But I also appreciate what he is trying to do here.

Nice work my friend. Not enough of our histories machinery and equipment is restored for future generations, it just gets shit canned without a second thought. Thank you sir.

How the heck do you remember how to put these things back together???
Excellent work. It's now a "museum" piece!
“OK, let’s go back to work“ funny 😄
Brings to mind the ingenious practical joke we schoolboys of the 50’s played. It involved connecting a hidden wire to the school urinals and another to the grid that the victim would stand upon. I leave it to your lmagination how the phone generator is involved.
Modern universal screwdriver is not fine for this devices.
It hurts me to see him using the smallest bit to tighten such large screws, especially since they're mostly brass. At the end, when he tightens the hand crank, you can clearly see it's leaving a mark.
Yeah and those are like custom hand made screws from a manual lathe.
I bet a gunmakers screwdriver would work better.
The comment by Y B below is correct. I was a telephone technician for more than 20 years, and winding one of these sent alternating current down the phone wires to make the phone bell ring. The voltage that it generated would have been around 80-volts. Because a phone bell is operated by 2 electro-magnets, it requires alternating current to make them operate in turn, making the bell ring. Once the ringing has stopped, a telephone operates on around 48-volts DC during normal conversation.
Since it was part of a phone, making it charge a new cell phone would be cool.
Make a module that has a capacitor bank that feeds a 5v step down converter, that powers a female USB port :)
Good luck though, although it would work, it will take a very long time to charge a cell phone. Also, the difficulty in turning will be related to the amount of current supplying, so you will probably need to add an inline resistor before the capacitor bank to keep the handle from being totally locked up when the capacitors are uncharged.
@Michael DiLorenzo Capacitor bank would allow you to be a bit inconsistent with your crank speed, large enough and it will allow you to take momentary breaks.
@@rich1051414 you could use a few li-ion with a bridge rectifier and charge circuit so it would charge up and then you could plug in your phone using a 5v regulatior
You could if you stepped down the voltage and rectified it to DC...but why would you want to? I definitely wouldn't want to be sitting there, cranking it for an hour. Now if you hooked up a small engine to crank it instead, then you'd have a small, lightweight generator that you could use to recharge batteries or whatever else you want to do...THEN you'd be in business.
@@ct92404 without the engine would be useful in places without ready power such as a natural park or campsite
add a capacitor and the led bulb will light up more consistently / not flash as much
Add capacitor across the output.
that would be my choice as well
AfroTechMods style?
It's bad idea, output is not constant polarity.
Not an electrolytic capacitor, that's for sure!
@@ct92404 It's pointless to add any capacitor. What purpose of it? Decoration? In AC circuits the any capacitor is a load which grows with rotates per time…
It drives me crazy that you don't have a independent buffing machine. 😱😲😳😩😦😞
Where do you find all this things ?

I like your work. But improving electrical performance is an extra job.
It's not his strong suit. That's why he never replaces old electric copper wiring and it's surrounding fabric. He's not an electrical engineer (nor am I for that matter).
It would be interesting to see him replace old wiring and cabling from scratch.
it certainly looks fun to load the smartphone in public with it.
„my battery is empty!"
„wait, I've got something here!"
this will be so funny 😂
@@TysyTube add a capacitor and a 5v regulator to it,then use it to recharge a small usb battery.
i think is 110v 120v
you can attach a power supply to reduce the voltage (with 5x usb port, for you and your friends). if manual cranking becomes too hard, please consult an electrical engineer to install an electric motor for the drive. that there is not something on the market is a mystery to me ... :-)
Sorry - a place without power: use a steam engine!
I kept looking for a fly or bee to be buzzing all around the screen while he was sanding the wood. 🤣 I love his humor and I guess just expected something like that.
Turn it into a hand cranked taser
lol
You should give it to some school so they can teach students how the generator is working
How'd you keep track of the polarity of the magnets?
Probably why it took 2 hours to assemble.
He never tracked it, see in 13:24 - magnets should not attract when with same polarity, but on film does… Another film „let's polish f…unny thing, who cares about the laws of physics”
Use it with a restored small old engine and use it as a phone charger

@@TysyTube How about hooking it up to an Ohmibad?
Thanks...I always wanted to take one of those apart when I was a kid. They looked like magic, gears, magnets 🧲, wires, nuts and bolts...and it would give you a shock! I imagined all the different things it could be hooked up to....Thanks
Wood working and metal works... Perfect restoration... 👌👌👍👍👍
thank you 😊
The output is AC. It was used for ringing the bell at the other end, in order to establish the connection before talking. Normal output about 100 to 120 V at 25 Hz.
Just a suggestion, I don't know if it would work but have you tried something like a rock tumbler to get the little hardware shiny? Then you wouldn't have to stand there for 2 hours getting the smallest screws shiny. Or maybe use a little vibrating machine. Just a thought.
Either way it looks awesome. I love old school electric gadgets. What do you do with the stuff you restore?
Edit; miss spelled a word.
thank you 😊, maybe i will make a machine like that, will be more easy, but i don’t know if can polish, i keep all for now, but i want to make some giveaways at 100K
I know here in the states Harbor Freight makes this vibration machine that comes with different size and shape ceramic beads that are for polishing.

I don't know if you have anything like Harbor Freight in Europe but I'm sure you can find something. And I have no doubt you will be celebrating 1million subscribers one day. You do some awesome work.
@@TysyTube Pretty easy to make a tumbler but if you want a polished finish look into making a wet tumbler. People that reload often wet tumble their spent brass and it makes it look almost new. Might get on some gun forums to look around for ideas.
@@TysyTube If you can find a small rock tumbler or make one, I put small brass or rusted steel pieces in mine with a few handfulls of small steel ball bearings and very short clippings of wire, along with a bit of hot soapy water. It removes a lot of rust and leaves brass gleaming, and doesnt harm pieces or make them look too new
@@TysyTube www.amazon.fr/SMARTRELOADER-SR737-Tumbler-Nano-220V/dp/B004ZIO2FM/ This is the one I use to polish brass cases. They work quite well, and can use many different polish media.

Very nice work! I’ve been binge watching all your videos. FYI - when sanding wood, it’s usually best to sand in the direction of the grain. Going across the grain puts scratches across the grain that are hard to remove.

Don’t you need to push button to make drill work?
apparently he locked the drill in run mode.
manaquri yeah might be
It would never make a drill work anyway, because that is a voltage generator (see the amount of turns of very fine wire), not current. Its current would be in milliamps, a drill needs many amps to work, the Drill there was just a joke like in many of his other videos. look for them, he always has some good one or two sometimes.
