well it's a lathe ruclips.net/user/postUgkxN9zrzkkhnjUF5PQbuA_B1gYdsfCu9k6z but it wasn't what i would have anticipated. Headstock, tailstock, carriage apron are manufactured from aluminum now not cast iron. The spindle diameter for the bearings is too small allowing for a few play in the spindle so I am using some blue Loctite to take out the play.
Very impressed with your initiative. Quality work. Please watch your fingers when drilling and consider clamping rather than hand holding, I know from experience!
You not only can do machinist work ,you are also good at electronics! Nice job.
That is a true transformation, like transforming David Banner into the Hulk !
Oh! Brilliant broaching of that keyway!!!!
Although I do not understand all the ramifications and I am not a machinist this looks very nice! I thought DC was better but the operation and instant forward to reverse is superb!! Wow well done!
IIt didn't take me long to burn out my 500w motor on my chinese lathe so I replaced it with a 2400w motor from a useless mulcher I had ,as for the pulleys I changed them to multi-v [they last longer ] ,That enabled me to make a simple clutch I have made a lot of changes to my chinese lathe ,now I can make a reasonable depth of cut on alloy steels i
Had to upgrade my Sieg C3 as the board burnt out. Went with a C6374 from Ebay, a 60amp esc and servo tester, all powered by a 24v 25amp power supply.
I now have 2.7kw instead of 350w. It cost approximately $160au which is $30 less than the price of a new replacement board. It all works as standard, even the speed indicator.
You're solution is better, this is not a good induction motor application.
You should write an article detailing how to do it. I’m sure there are plenty of people who would love to be able to do the same.
Nice video! Thanks for sharing. Very satisfying end result
Thank you for showing, nice work, also good video. Have a good day.
Muchas gracias por mostrar su trabajo, su diseño y terminación. Su video fue muy constructivo, tenga usted un buen día. Desde Uruguay lo saluda Charrua
Thank you for this video! It's very easy solution but with a big upgrade! good job!
boa noite rapaz vc sabe o que está fazendo pra modificar o motor de forninho e a elétrica vc esta de parabéns 🤣🤣🤣🤣 ótimo trabalho que vc fez fica com Deus abraço
First, always cover the ways with a board when you change the chuck, Second, a good set of taper roller bearings in the spindle will do wonders for runout and noise.
Good Idea and great work.
But IT can be dangerous.
Each three-jaw chuck(Dreibackenfutter) only has a certain maximum speed limit!!!
Really impressed with your anvil and the hammer you used. Very nice video and appreciate the acoustic guitar background. Thank you sir.
Nice job👍👍👍
Muito bom seu vídeo , fez mais alguma melhoria no torno ?
Well done young man someone in your life took the time to teach you skills that you demonstrated during this video. Who ever it was, your dad an uncle, a friend or maybe a shop teacher. Whom ever it was “ Bravo” for taking the time to teach him right, skills that will last him a lifetime and memories he will carry and share for ever. America needs to get our kids away from the shootem up videos and out to the garage or basement to share more one on one time and build stuff. Young man keep up the good and impressive work.
Excellent! Never occurred to me to go AC with my mini lathe. I have a 3/4 hp 3ph motor laying around that I've been wondering what to do with. I may have to try this. Well done!
How slow can you take the speed on the lathe now and still get a good cut? Are you happy with the motor upgrade still? Thank you so much for the video!
Nice mod for an old mini lathe. The new 7x16 mini lathes from Little machine Shop and Micro mark come with powerful brushless DC motors that have so much low end torque that the noisy 2 speed gearbox is not required. Their mini mills use the same motor, and they are really quiet as well as powerful.
Yo lo he echo en el mío, y es lo mejor que puedes hacer , no hace falta tener corriente trifásicamente , ya que las tres fases se generan en el control
Good music as well!
ales, te doy un truco para convertir tu sierra de banda que corte automaticamente, 1 paso el tornillo del eje donde balancea la sierra aloja en su interior un muelle que es el que te sube la sierra, quitaselo y ajusta la presion del tornillo de tal forma que la maquina caiga sola pero sin que tenga juego , 2 el boton (Pulsador) del mango lo suelta e inviertes los contactos con el fin de que si no lo pulsas la maquina se enciende y si lo pulsas se apaga.
Very nice work sir.
Con esto se acaban esas pequeñas correas, que se rompe casi siempre y que son caras, esta transformacion, el torno es indestructible, ademas trabajas con poderio , no decae el motor, excelente
Interesting conversion to a much better three phase variable frequency controlled lathe - more torque, wider speed range. Just shows what can ve done by those who try. BobUK
Now that was a sweet ass job on that . now you have a bad ass motor with plenty of power great video !
Nice job; well implemented. Have you had any issues in the gear train with the big increase in power?
Nice work!
Good job Mr Gonzalez
Un muy buen trabajo, tendría que hacer el mismo trabajo a mi G4000 que el motor esta fallando y no tiene fuerza suficiente, y muchas gracias por compartir, tenga usted un buen día.
Very nice work, I must do the same to mine G4000 because the motor it is not working very good. Thank you for sharing, and have a good day.
I can't believe you held that bracket with your hand while drilling it. Good way to tear your fingers off.
I almost learned the hard way myself, although it was a much smaller part and at worst would only have cut my finger open; still, doesn’t take much if the drill bit catches the work.
Nice work Only the ratio of poly should be minimum 2 to 1 in direct paddle
What does this mean..? Can you re phrase please for a novice.. Thanks.
Muy buen trabajo, pero el stop siempre es un contacto normalmente cerrado y has puesto un NO, el caso es que luego te funciona bien, es posible que lo cambiar a posteriori?
Que tal! Gracias. Esto puede servir para cualquier mini torno, me imagino. Son muy similares estos mini tornos chinos.
when I bought that chinese lathe 20 years ago it came with an ac motor.the thin belt had some kind of problem they kept shredding and at 35 dollars back then the lathe wasnt worth it
Next is, I suppose, to install ball screws, steppers, controller and to have CNC lathe :-). Excellent job!
Good Job. Now it have power enough.
I wouldnt have replaced that motor. Some gearing changes are all thats needed on these Chinesium lathes. I would have however invested some money into those spindle bearings because your sound like they are going to explode any second now. happy machining !!
Aless muy bueno tu video. Cuando harás uno mostrando las bondades que da su nuevo motor.
Puedes darnos las características de tu nuevo motor?
Un saludo desde Chile

Interesting technique.
Damn, neat! Never thought of using my lathe as a scraper! Woot! I was going to grind down my key but instead I'll scrape the key slot in the pulley! Sweet
Awesome 👍👍👍
good job now all you need is a quick change toll post and a tool rack with all the parts on it keep up the good work. my family say we are related to a Spanish general the torre part .
As you did the speed display. It is a mathematical transmission in the inverter or a speed sensor on the spindle.
Excelente trabajo!!!
Cuando taladraste la chapa de metal que doblaste en 90º, no fue seguro que la sujetaras con la mano de esa forma, has tenido suerte de no hacerte daño en el dedo
Enhorabuena por la mecánica. La eléctrica nos has dejado con muchas preguntas. El motor parece trifásico amenos que tenga el condensador dentro de la caja de empalmes. Mejor trifásico porque tiene mayor par de arranque. Esto concuerda con el variador de velocidad V/F . He encontrado uno parecido de menor potencia ASX-AT1 pero 750X ( 0.750kW ) y es entrada monofasico 220v y salida regulada en velocidad ( frecuencia) trifásica. ¿Voy orientado?
Madre mía, me recuerda mis primeros años en la mecánica... Que nostalgia 😋
Carai que modificación mas guapa, parece facil pero deve ser super difícil . Enhorabuena👏🏻👏🏻
Excellent work.
Great work. Gives others the inspiration to do likewise... Good video.
This is definitely a huge improvement to these bench top lathes.....well done.
Tudo ficou muito top, show demais meu irmão parabéns aqui do Brasil!!👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
Really nice Aless. Just a question though. Was the main reason for the change more power only or are there other benefits you were looking for?
a bit late but a i believe that AC motors have full torque at lower speeds which DC motors do not
Muito bom, prendendo comprar um torno deste modelo e fazer as mesmas modificações.
Ainda vou modificar para que ele se torne CNC.
Parece que você pretende fazer o mesmo.
Uma dica é você fazer um sistema para lubrificação do material usinado, luz e proteção telescópica ou sanfonada nos fusos, barramento e carro transversal.
E mais uma dica é de instalar paquimetros digitais de profundidade no carro transversal, assim quando você for usar de forma manual terá um indicador digital que lhe dará precisão.
Faz uma base que colete e filtre o óleo solúvel que você vai utilizar caso faça o sistema de lubrificação.
Super boulot mais comment tu fait les poulies ?
Well done brother.
Excellent job.
Show Off! Nicely done!!!
Can you still cut threads with ac motor conversion?? Does after conversion the lathe has all the capabilities that had before with the dc?? especially threading and auto feed?
Yes, you can, as the connection between the main spindle and the feed spindle is untouched. At around 06:05 you can see this quite well.
Молодец!!! 👍👍👍
Hi, how it works the rpm indicator?
I mean, the proximity read the magnet on the axis bar, and then? It gives directly the signal to that display?
Excellent work!
Hola, fenomenal la mejora. También estoy mirando tornos y coincidencia los optium comercializados por aslak me han llamado la atención porque de 2a mano están muy subidos de precio aquí en Canarias. ¿De la gama optium a partir de qué modelo recomiendas? ¿con variador o sin variador?
Un saludo y gracias.
that model lathe is now called TU2004V and it is variable like the older model
Mais um escrito no seu canal tamos junto abraço que deus abençoa
Good work, have fun with your upgrade and continue to show more of your ideas. Herri in Kunming China.
Very nice Aless! I like your step wise approach to this project.
thanks mister
Estupendo vídeo, muy instructivo si sabes trabajar, estaría fenomenal que pusieras el enlace del cuenta-vueltas.
GREAT JOB YOU DID !!
Buen y bonito trabajo, gracias por compartir!!!
Que tal te ha salido ese torno? Estoy en la posibilidad de adquirir uno de similares características, y la verdad que no hay muchas referencias sobre ello.....
Muchas gracias de antemano y saludos desde Canarias.
Para trabajos pequeños y precisos, recomiendo los tornos americanos Sherline o los alemanes Proxxon.
Nice work!! Impressed!!
Very nice! Is that a proximity sensor? What function did you have it perform? Also are you able to provide a wiring diagram? Thanks!

Aless, Nice Modification! May I ask what is the H/P of your new Motor?
@Jayce Decker Uh...? Why?
Oi! Estou procurando escovas de carvão para o modelo Optimum 93ZYT005 aqui no Brasil, mas não consigo achar de jeito nenhum. Tem alguma forma de substituir ? Ótimo vídeo, muito obrigado.
Nice! Would you have/share the schematics for the variable frequency drive?
He shows it at 5:55, it’s an XSY-AT1, 2.2kw I think (from the 2200 in the model number field). They’re a popular cheap VFD, just search it on aliexpress. I think you can find them for $70-85 shipped.
such a question, would you buy it again with this money?
excelente idea como no tengo luz trifasica lo boy instalar con variador de velocidad entrada monofasica salida trifasica
Foley model and size?
muy bueno.. que transmision dentada estas usando??
What size toothed pulleys did you use? and what timing belt profile?
Also, what pulley system are you using?
i think I would have bought a quick change tool post first...
Hi, I'm thinking of buying a lathe. I have seen with brushless motors. Would you recommend with that type of brushless motor? thanks for your answer
Hola, tengo un motor trifásico de 1.1 KW con 2860 rpm en conexión con VFD XSY-AT1. ¿Cómo solucionaste el problema del torque al tornear roscas? No sé. ¿Me pueden ayudar con la configuración de parámetros? Muchas gracias.
Saludos MyGreystoke
El trabajo esta excelente pero tengo un torno similar y no le veo la necesidad de hacer ese cambio aparte de la durabilidad que el motor de ca dará contra el de cd, interesante seria hacerlo cnc
Hola Fernando. El problema es que la placa electronica o el motor acaban estropeandose como me ocurrió a mi, además el uso recomendado de este torno era 30 minutos. También tiene más potencia. Por último, tengo planeado hacerlo cnc y el variador de frecuencia puede ser controlado por el sistema
@@danyel6156 los variadores de frecuencia son para 3 fases , aunque sean alimentados por 1,2,3 fases , la salida es para trifásicos , los motores Brushless tienen configuración delta o estrella según el caso por eso también es apto para un motor AC o universal
Compañero otro estupendo video !!! Haber cuando uno probándolo a full , un saludo 💪💪
Lovely Job man !
Primero que nada gracias por compartir este exelente video de verdad yo tenia pensado hacer algo similirar a mi torno marca grizly es identico al que muestras, pero no sabia ni por donde comensar mil gracias haora ya tengo una idea , respecto a la nececidad de convertirlo yo lo veo como algo inevitable devido a que todos estos tornos estan mal diseñados el mother board el motor y las ligas que usan de bandas son delo mas corrientes y terminan fallando el mio fayo alos 6 meses y despues alos 2 años me canse de arreglarlo y esta guardando polvo desde entoces pero despues de este video no mas ! ademas de ser una mejora tambien pienso se puede aumentar el hp del motor el mio era de 3/4 hp pienso poner uno de 2 hp !
can you give me the link where you bought the engine speed display (rpm)? thank you
the last lathe bender :) kingman :D
Nice job , well done.
Nice soldering :)))
Simple and effective, nice !
Cool mod I’ll have a look at doing this when I get mine
Hello. The optimum choice is 180x300 or proxxon pd 250 e. What is the reason.
Nicely done!!!
What's good about going ac? Just wondering what all the benefits are. 💪
Well done and that is a very nice shop you have.
