MINI LATHE TRANSFORMATION! DC motor to an AC motor 🔧 [Optimum D180x300] 

well it's a lathe ru-vid.comUgkxN9zrzkkhnjUF5PQbuA_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.

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!!!!

Very impressed with your initiative. Quality work. Please watch your fingers when drilling and consider clamping rather than hand holding, I know from experience!

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!

Thank you for this video! It's very easy solution but with a big upgrade! good job!

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

Nice video! Thanks for sharing. Very satisfying end result

Really impressed with your anvil and the hammer you used. Very nice video and appreciate the acoustic guitar background. Thank you sir.

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.

Now that was a sweet ass job on that . now you have a bad ass motor with plenty of power great video !

Nice job👍👍👍

2:22 Interesting technique.

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

Good Job. Now it have power enough.

This is definitely a huge improvement to these bench top lathes.....well done.

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!

Good music as well!

Madre mía, me recuerda mis primeros años en la mecánica... Que nostalgia 😋

Tudo ficou muito top, show demais meu irmão parabéns aqui do Brasil!!👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

I can't believe you held that bracket with your hand while drilling it. Good way to tear your fingers off.

Nice work!

Carai que modificación mas guapa, parece facil pero deve ser super difícil . Enhorabuena👏🏻👏🏻

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

Show Off! Nicely done!!!

Muito bom seu vídeo , fez mais alguma melhoria no torno ?

Good job Mr Gonzalez

Next is, I suppose, to install ball screws, steppers, controller and to have CNC lathe :-). Excellent job!

Excelente trabajo!!!

Great work. Gives others the inspiration to do likewise... Good video.

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

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.

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.

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 work.

Good Idea and great work. But IT can be dangerous. Each three-jaw chuck(Dreibackenfutter) only has a certain maximum speed limit!!!

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

Well done brother.

Awesome 👍👍👍

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.

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

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 .

Excellent job.

GREAT JOB YOU DID !!

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!

Молодец!!! 👍👍👍

Que tal! Gracias. Esto puede servir para cualquier mini torno, me imagino. Son muy similares estos mini tornos chinos.

Very nice Aless! I like your step wise approach to this project.

Excellent work!

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

Nice work Only the ratio of poly should be minimum 2 to 1 in direct paddle

Nice work!! Impressed!!

the last lathe bender :) kingman :D

Mais um escrito no seu canal tamos junto abraço que deus abençoa

As you did the speed display. It is a mathematical transmission in the inverter or a speed sensor on the spindle.

Simple and effective, nice !

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

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?

Cool mod I’ll have a look at doing this when I get mine

thanks mister

Good work, have fun with your upgrade and continue to show more of your ideas. Herri in Kunming China.

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

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.

Nice job , well done.

Great work

Nicely done!!!

Excelente, Aless!!!

Compañero otro estupendo video !!! Haber cuando uno probándolo a full , un saludo 💪💪

molto bravo, complimenti :)

Nice soldering :)))

Lovely Job man !

Nice job; well implemented. Have you had any issues in the gear train with the big increase in power?

Muy bueno. Gracias, mi hermano.

Muy interesante un saludo compañero

Super boulot mais comment tu fait les poulies ?

Bravo très intéressant

great job my dude !!!!!!

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.

Well done and that is a very nice shop you have.

Estupendo vídeo, muy instructivo si sabes trabajar, estaría fenomenal que pusieras el enlace del cuenta-vueltas.

Nicely done.

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?

i think I would have bought a quick change tool post first...

Yes sir, git her done.

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

salut j aime bien ca n a plus rien d un tour chinois tu demande combien pour en modifier un comme ca ca m interresse bonne et heureuse année

Super

muy bueno.. que transmision dentada estas usando??

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?

Nice! Would you have/share the schematics for the variable frequency drive?

Magnífico vídeo!!

One tools parkside=👍🏾 good choice

In the next video he will take the DC-motor from the lathe and put it on his Dremel tool! ;)

super

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?

Also, what pulley system are you using?
