- restoration old bike dynamo made in ukraine.
An old bike dynamo wich was made in ukraine.
The dynamo is not used since long time.
new electric bikes don't need this type of dynamo
anymore, but i will restore it only
to remember childhood bikes.
I used epoxy resin to restore a curved & damaged part in
the aluminium.
Principal dynamo materials are alimunium,
copper wire, bakelite and reinforced plastic.

The hole you sealed with epoxy was to lubricate the rotor shaft. It was to prevent wear by lubricating the shaft by dripping thin oil on the place where the felts were and ensuring that it rotates easily.
None of the generators I had like this had a lubricating hole. All mine were lubricated with perma-lube from factory. No regular lube required. Such brands were Miller, Sanyo, & Panasonic. Miller from the UK, Sanyo & Panasonic from Japan, & one I nearly forgot is Union, from Germany. All were good. This one here is probably a rare one.
Thank you Christopher for the clarification, you have right.

This one was made shortly before they switched from oil-vaseline mixture (which required to be re-oiled periodically by the user) to a more permanent grease composition, which happened in the later 60s for this manufacturer (FER from Ruhla, GDR). Union already did it in the mid 50s, as the western (non-cοmmunist) part of the country probably made that grease earlier or cheaper.
@@westelaudio943 I’ve never had to lubricate any of the dynamos I’ve had on my bikes. I did see this one had the felts soaked in lubricant.
@@christophermarshall5765
Yeah. I own several variations of this basic design, and only one (year code: 1966) is oil lubricated. The original design was made from 1961-1966 and thereupon, slight changes were made, and more until the end of production ~ 1990.
I also have Union made ones from the 50s to the 90s (2000s?) and none of them have any oil valve whatsoever.
I would also say that Unions are generally slightly better devices, more power output at lower speeds and less likely to slip, and the ones from the 70s are probably the most efficient and very easy to activate.
Bike dynamo. Good memories from childhood. And the sound from wheel:):):)
Oh yes ! That's right
..i had 3 in my bike :)
You did a good job! Congratulations!
It would be interesting to see it working again, generating energy for a light bulb, for example.
Much appreciated Rodrigo. Will take care about your advice in a next similar project 🙂
Made in East Germany by FER. Mid 1960s.
Used to have one on my Raleigh Grifter back in the 70s
Gareth Judd oh yes 😉
Make no mistake, this type of dynamo is still in production, are still being sold and used on modern bicycles over here in the Netherlands.
Hi there Hans, i didn'tt know that.
No. You are probably thinking of a similar looking device made by "Nordlicht", "Anlun" etc.
The company who made those here (FER, Ruhla, East Germаny) went bankrupt in the early 2000s, and they haven't made this model since 1990. This iteration here is from the early to mid 1960s.
in 1960s i used to break tis bicycle dymamo to get its magnet for a fun..now tis dynamos considered antques.even cant see.one in the market or towns anymore.used to ride bicycle in deep dark jungle forest only the bike light using dynp those days...now days i saw they are selling tis old bike dynamos in antique shop with a very high price
Well, it is a childhood memory.
New versions of the bicycle dynamo light set are still made. They are even made with LEDs replacing the short life incandescent bulbs (which are also hard to find correct replacements). Go on line and do a search. You will find these sets.
I like watching videos like this, and the people who take the time to restore things made in times of past, bringing new life.
Wether or not to use is questionable.
The only thing im not sure of really is the amount of dislikes on this video. 🤔
Anyways i enjoyed watching it, and respect what you do. I thank you. ☺️
Thank you very much 😎
Nice trick with the drill and sand.
Some of these old bicycle generators used alnico magnets, and if you take them apart without a magnetic keeper you loose some of the magnetism, this one looks like a ferrite one however.
Thank you buddy, also for the trick about magnet 🙂.
for those who trying to find this moment in video: 10:00
How can the magnetic field of an AlNiCo magnet (or any other permanent magnet) weaken when it is removed from the iron cores of the coils? That would be new to me. The magnetization of the permanent magnet is not stressed when its field passes through the air from pole to pole, in contrast to when the dynamo generates electricity and has to work against the magnetic resistance of the coils.
I have an old dynamo with a block-shaped two-pole magnet made of AlNiCo material with two rotating pole shoes made of iron and two stationary pole shoes of the coil. The housing is made of die-cast zinc, coated with aluminum paint. The dynamo must be from the 1950s.
I have opened it many times, recently to re-oil it, it can be easily unscrewed thanks to the fine thread. The magnet was certainly never weakened.
Okay, I now found something about it: AlNiCo permanent magnets have a relatively low coercive field strength and should be provided with magnetic keepers for storage and transport to protect them against demagnetization by external fields. The magnetic field of the AlNiCo should not be in danger for a short time and without external magnetic fields.

Thank you buddy, really much appreciated.
good job
Love From Bangladesh ❤️❤️❤️🇧🇩🇧🇩🇧🇩
Many thanks. Much appreciated. 😎
MUITO BOM VERY GOOD 👍👍👍 🇧🇷
Thank you from tunisia to brazil.
This dynamo is different I had never seen. A rolled coil dynamo i have seen winded coil dynamo only it's different and goosebumps nice video i would like to give thumpsup 👍🤗
well said, thank you very much 👍
Thanks for good idea for method of abbrassive .👌👍
You're welcome 😎.
On my 12th years old xmass. Santa brought me a beautiful green bike! Immediately I call her the Green Hornet. Well my uncles cane with the idea of giving us money as present. There were a classification older cousins $25, my brother 15 and me $5. Some of them gave me $10 an my grandmother ( and partner in crimes) $20. The very first thing I bought was a beam with its dyamo beautiful cromed beam casing and the mighty dynamo buzzing like a crazy bee. Oh! That was a Christmas that I'll never forget.
Beautiful memory that can not be forgotten.
Memory of good old days
Yes buddy, that's real.
Gosto muito deste trabalho escrarecido.
Thank you buddy, much appreciated
Fantastic.
Thank you buddy 😎
В детстве у меня был велосипед Урал на переднем колесе препился точно такой же Динамо он вырабатывал ток и загоралась лампочка чем быстрее набирал скорость тем ярче был свет
beautiful childhood memories.
Looks good since you worked on the bike dynamo.
Yeah thanks George
Excelente trabajo!!Lastima que tapaste el orificio de lubricación con epoxi!
Thank you buddy.
nice job
Many thanks 🙂
Very nice job 👍 you did well to round off those rivets. Nice to see it get a second life. I'm not sure why you plugged up the oil hole though ? Job well done.
Thank you Austeration. Before i began the restoration, I checked another original dynamo, and didn't find any holes. I thought the one i plugged was made accidentally.
@@RestorationInside You are probably right. I just seem to recall as a kid having one on my bike and always had to oil it and keep those felts lubricated. I think it might have even had a small cap on mine that sprung shut. I think I still have the bike but not sure if it's still all together. Regardless you still did a fantastic job.
He plugged the oil hole because it is going sit on his coffee table?
The original dynamo don't have that hole but many people did'it for lubricate with oil...I know for sure because my first bike was from Ukrayne-USSR in 1985.They sold bicycles with headlights, dynamos, and red taillights. And the dynamo was identical with this from the video.
Amigo ,tinha nesecidade de desenrrolar a bobina? outra coisa faz um video com ele funcionando ,fiquei curioso para ver .walew sucesso para você!
OK, will do in a next similar project.

Quando devi ribattere il ribattino, devi prima farci un forellino sul punto da martellare, magari di qualche mm. Cosi' con un bullino svasato, con pochi colpi lo schiacci quanto ti serve! Per quello che riguarda il restauro, hai fatto un buon lavoro! Ciao!
Thank you Paolo, really much appreciated, will take care about your advice in similar projects.
Congratulations, it turned out great, and for small pieces, I give you an idea, a toothbrush, that's what I use!
Thanks for the tip!
Самое главное с душой ковырялся без принуждения. А если не получилось ничего не поделаешь не всегда по нашему получается
Hi there.
@@RestorationInside и тебе от всех привет
Best👍
Thank you buddy .

Thank you.
Since you jumped at the end straight to the "final look" i can assume the coil is a bust and you haven't been able to make the magnet rotor spin freely. The coil itself looks messy, you should have done it manually. Now it's just pretty on the outside, but non-working.
Anyway, that's your opinion, i had commitments, that's why i didn't recorded the assembly and also the test.
@@RestorationInside you had commitments so you didn’t finish the video and posted it unfinished?
@@MisterRorschach90 hello, regarding the assembly and testing, i want to inform you that it takes time for work and also more time for editing to get an interesting content.
Looks amazing! But he has a point. I just discovered your videos, and really enjoy them. You're obviously very meticulous, in what you do. So why not show the complete working fruit of your labor?
What makes you think it doesn't work? Were you there when he tested it? A coil does not need to be wound neatly for it to work!! There is no reason why this won't work. You're a "nit picker".
Can you explore me how many of turn of coil, identify the N and S of magnet
Really no idea.
Great job, but what does it do?
Thanks, this is a dynamo, a small electric generator, it is used on bikes
I have a same item but that is never used.It is the HH Miller co make and from uk.All set includes head and tail lamp also ,that seems to be in show room condition.
That's good.
You are in slow motion mode really!!!
Will try my best in a next project
now, how are you going to lubricate the spindle? you blocked the oil hole with filler. the felt washers were probably meant to retain oil. apart from that -- a nice restoration
Thank you.
Sem funcionar não é restauração de verdade!
I didn't got enough time to record test and assembly.
You could do with restoration of some of your tools, plus you spray wd 40 like your life depended on it
You have right 😉
Why did you covered that hole?
It had a purpose. I think it was made for lubrication.
The coil looks so bulky.
Put it on the test.
The dynamo RPM is not extremely high, there are other dynamo type type which are self lubricated.
腳踏車大燈的發電機嗎？
Yes, for old bicycles.
Hey dude, I wasn't thrilled when you didn't try the dynamo after the renovation
I mentioned that I didn't had enough time to record and edit the dynamo test, will do in next similar projects.
U blocked the necessary hole?
There are types of dynamo that do not have holes in this location.
@@RestorationInside - True, but having an access hole in such a generator is a sign of forethought by the designers because the bearings will need to be lubricated at some future point. With generators that do not have this hole the only way to lubricate them is complete disassembly, if that's even possible for the owner.
👍👍👍👍👏🤗
Many thanks Gerhard.
@@RestorationInside
Thank you for your answer. 😀
You're restoration was very professional.
Like German workers at their best times.
✨👍👍👍✨
هل نستطيع ان نعرف ماهي هذه الالة وبماذا تستخدم
إنه مولد كهربائي لدراجة هوائية
Very interesting, but after the restoration, you failed to show the dynamo working.
I will do it in a similar other videos.
voltage test not shown..
Will do i next similar projects 🙂
No assembly? :(
Sadly not in this video 😄
Я з України)❤❤❤
Hi there, nice to hear that.
Great but you sprayed a lot of WD40 😃
Thank you Buddy. Regarding WD40, will try to use less next time.
@@RestorationInside you restoration was awesome though 👍
It looks nice, but now, let's see how it works.Otherway, it's just a piece of metal.
video editing require lot of time, and i had a commitment, that's why i didn't record assembly & test.
@@RestorationInside So, should I understant you gonna show us how it works this dynamo, right?Well, in this case, you make me curious, because, menny years ago(about 45)I had a very goog bicicle, named exactly like this :Ukraina".I repeat, a very good and strong bicicle.
You didnt show the full re-assembly process! What a pity!
Will do next similar project.
u may show it Working.
Will do in next similar project.
E a montagem?????
I will record it in next similar projects.
I regret that the reassembling process and the function test were not showed
Will do in a next similar project.
it's too long, only the dynamo is shown, the old one is really very inefficient
Дитинство прийшлося на час дефіциту батарейок та акумуляторів, тому така штука дозволяла їздити на вельчику зі світлом крізь темряву вулиць свого міста 90-х років...
greets from tunisia to ukraine.
whats about llectrical function. Not completed. No restoration. All work just for fun and to make money with YT.
I had a commitment, i didn't had enough time to record the dynamo test, will do in next similar project.
Does it work??? 😳🙄😞
In fact i didn't test it, but normally it works without issue.
Restored , but does it work ? I guess we'll never know.
I didn't had enough time for video editing, that why i didn't shot the dynamo test.
Советские динамки были намного надежнее.Там и ролик стальной был,и втулки меднографитовые.
That's good.
Never did show if it works
It could be a paper whgaight now
Will do in next similar project.
Não gostei, não concluiu a montagem, já mostrou pronto
will upload more details in next similar videos.
Not correct. Made in USSR!
OK Buddy
👏👏👏👍
Thank you buddy 😎
Too slow motion... 😤😤😤
Will speed up next projects 🙂
@@RestorationInside good video. It's just that it's slow. Slow doesn't mean bad 👍👍👍
👋👋👋🤝🤝🤝👍👍👍💖💖💖🇬🇷
Many thanks Loannis.
Millar brand made in india
Ok.
Procedimento muito lento, chega a cansar de assistir, REPROVADO
Will do better regarding video editing for next projects.
Não. Não mesmo.
!
After all that and you didn't show it working... Spin it up with a drill and at least show the viewers it works. JMHO
You have right, will do in next similar projects 😎
no muestra nada al final se arma como por arte de magia y no muestra si funciona o no...pesimo video
I didn't had enough time for video editing, that's why i didn't shot the test.
E il montaggio? E il funzionamento? Un video a metà non serve a niente.
Ok , will do in next similar project.
@@RestorationInside You topped, you made laugh.
So slow waisting taim
Maybe 😎
All that and no shots showing it working? Lame. Not actually "restored" then.
Will try better next video.
Taking too long
incomplete .work like a lazy
🤔
So much time lost on tidying and polishing , but then no end result which is the most important thing!!
How do you know that the dynamo is made in Ukraine? You never seem to say. Live up to your title.
It's made in East Germany by FER model 8007.4 built 1961-1990 this is an earlier iteration, mid 1960s.
Что за дичь, катушку можно было аккуратно намотать, почему не показал, что работает.
Will try m best in a next similar project.
А оно хоть работает? А проверить?
i didn't tested it on a bike yet.
@@RestorationInside Well, it's for nothing.
Invest in good quality tools. You'll not regret the cost. You've got the money to do so, or you wouldn't have a You Tube channel. Use a tool correctly. Screwdrivers are not chisels, and needle nose pliers are not high quality grippers. Invest in good tools. Make your tools do the work, not you. Don't be cheap. There's no honor in it. Be professional, not on the cheap. You'll look better and show that you know your tools.
Thank you for your advice, regarding the investment, I will take care of it more in the future.
slow, sluggish
Will try my best in next projects.
