Repair of angle grinder BOSCH PWS 850-125 - rewind motor armature

In this video I repair angle grinder BOSCH PWS 850-125. Despite the nice appearance the armature of the electric motor was defective. For rewinding I used thicker wire than originally mounted (diameter 0.355mm instead of 0.34mm). The free space in the armature grooves allowed me to do this. I also replaced the armature bearings that were loose. See what I got.

Build yourself an arbor press next, a copy of a Dake made from scrap metal. Save the shock loads from hammering on bearings.

[@valsworkshop]

Thank you. Yes, you need a press.

Hola me podrias compartir el modelo de tu soldadora de puntos para el colector conmutador??? Y me puedes decir como hacer y que voltsje tiene tu probador de inducidos al que le pones la navaja la segueta!!! O puedes hacer videos de estos equipos que utilizas por favor!!!! 🙏🙏🙏
Hello, could you share the model of your spot welder for the commutator collector? And can you tell me how to do it and what volts does your armature tester have to which you put the knife?

[@valsworkshop]

Hola, la soldadora la hice yo mismo, pero aún no está terminada, la reharé. Cuando reviso la armadura del motor, aplico un pequeño voltaje de 5 a 10 voltios a través de un transformador reductor.

[@ivonnevazquez4098]

@@valsworkshop Hola muchas gracias por responder... El voltaje que ocupas es de corriente alterna o corriente directa o no importa?.... Y estaría muy interesante que nos pudieras compartir un video de la soldadora de puntos de colectores para verla y poder hacerla una porque no he encontrado información al respecto y necesito una Te agradecería mucho saludos mucho éxito!!!
@valsworkshop Hello, thank you very much for answering... Is the voltage you use alternating current or direct current or does it not matter?... And it would be very interesting if you could share a video of About the spot welder because I have searched for information and I have not found good information about it, it would be very good if you made a video of it, I would be very grateful because I am very successful success greetings

[@valsworkshop]

@@ivonnevazquez4098 Hola, el voltaje es variable. La máquina de soldar está hecha sobre la base de un transformador de un horno microondas y una placa NY-D02 comprada en Aliexpress. Pero lo reharé: quiero agregar otro transformador para aumentar la potencia. O inicialmente necesita tomar un transformador más potente.

Hi, what is the brand and model number of instrument that you're using at 2:55? thanks

[@valsworkshop]

Hello, manufacturer Ullco, I don’t know the model. Produced around 1970-1980 in the DDR
