- Hi everyone!
This is the second video of the series about repairing your lathe/milling machine's motor.
In this video, I show how to adapt a new commutator, thus avoiding the need to rewire the rotor.
I have done this on my machines, and they have been running great for years.
As always, if you have any questions, I will be glad to help you.

Glad you are still there! Cheers from Texas
Thank you so much for watching and comment, it is very appreciated.
As is said: "satisfying video". Cheers Luiz!!
Hi, thank you so much for watching my videos and comment, it is very appreciated.
I will pray for you. Take care of yourself my friend.
Paul, I warmly thank you!
Another fantastic video, Luis. Thank you.
Thank you for watching and your comment Harold.
More great work my friend, stay safe.
Great Repair
Your work is always impresive. Thank You!
Hi Paul, thank you for watching and kind comment.
Your craftsmanship has no bounds. That motor work should cost 1000+ dollars for the detail and precision.
Hi my old friend, I'm glad to see you, you know, to ask a new motor here comes close to this price, so I recovery it lol
Thank you for watching and the kind comment.

Siempre es un placer verle trabajar. Nunca deja de comprenderme sus conocimientos.
Muchas gracias por compartirlos.
Un abrazo desde España.
Muchas gracias por ver mis vídeos Francisco, estoy muy contento por ello, hoy publicaré el último vídeo de esta serie sobre la recuperación de un motor.
Un gran abrazo desde Brasil
very good video. Learnt something
HI John, Hi, thank you for watching and comment my videos, it is very appreciated.
It's a joy watching you repair that motor, unfortunate about Brazilian import issues but it sure has made you skilled craftsman!
Hi my friend, thank you for watching and comment about that.
That's right, a tremendous difficulty to import things here, but surely this has a good side, that's why I share, I imagine other people going through the same problem with parts etc..
Greetings from Brazil.
Luiz
Boa tarde. Muito bom meu amigo. Saudades dos seus vídeos. Lembro do inicio da sua oficina kkk!!!!
Valeu por comentar Alexandre, quem sabe vc possa vir aqui qualquer dia também.
Abraços
Looks as good as new. I hope your kidneys are OK.
Ótimo vídeo. Desejo melhoras. Forte abraço.
Muito obrigado Vinicius, fico feliz que tenha gostado, a parte final é a melhor e devo postar ainda hoje ou amanhã.
Você é muito habilidoso! Parabéns e obrigado por compartilhar
sherline shipping to europe is also very expensive. typically ~300 eur extra for shipping here... sherline use only 1-2 day express services around the world. after some emails, i can use now "dhl standard" (for 200 eur). maybee this helps a little. thanks for your video. best regards
Like Here, you know, in Brazil every international purchase has a price increase of about 80%, taxes, shipping, and even in some cases 100% more with fines for price difference, my country is crazy.
Thanks for watching and your comment.
Eu morava a 10 km da fábrica da Sherline em Vista, CA. talvez se você precisar de alguma coisa, você pode obtê-lo para o seu aniversário :) Muito obrigado por esses vídeos instrutivos. (goog traduzir)
Thank you so much for watching my videos, the last part coming soon, hope you can see it.
Oh! My birthday was last January 19, but it is nice idea, I'm needing some arts for my machines.
I have many things to show yet.
Amazing!
Thank you Rus!
This is quite an amazing repair. But for someone who started in Electronics that was a horrible Soldering Iron Tip. Can’t you buy new Tips in Brazil?
Well observed by you, yes, I have new tip for the soldering iron, but I forgot to change them in my eagerness to show the result.
Thank you for watching the video.
Luiz, em 23:08 você fala a respeito do balanceamento do rotor. Como isso é feito? Você tem algum vídeo pra indicar sobre este assunto?
Lori, o balanceamento do rotor é importantíssimo, evitando vibrações que tiram a vida útil dos rolamentos do motor, desgastes prematuro de escovas, e em alguns casos mal contato do enrolamento além de ser desconfortável usar quando vibra. Todas oficinas de reparo de motor tem máquinas de balanceamento e é feito de forma simples e precisa, uns removem peso tirando material e outros adicionam, nos dois casos o resultado sempre é alcançado.
Where did you get the new commutator and what size is it
Very Nice, Where did you buy the commutater and what is the part number
Hi Ron, thank you, so, in Brazil has some factories of these Dc motor collectors, (commutater). It does not have a specific part number. The important thing is to have 16 blades and a compatible diameter.
Soldering is not so good idea. It can be easily desolder by heat and inercia.
I have working for 3 years other two like that here and more 3 for friends, until now no had problem. The soldering is only to ensure electrical contact, you should note that before soldering I pinned the contacts together with the original ones by hammering.
Good work any way. I have been seeing your microtool videos for years. And it inspired me to bought my first sherline clone milling machine and make my first videos like yours.
Infinitely happy to see you had subscribed.
Thanks a lot for it. Very happy.
