Motors from washing machines have average technical indicators, so the area of their use for making machine tools is not so extensive. For some projects they are weak, for others they are too slow. By applying this idea, you can make them 3 times more powerful or faster.

Gearbox connection process
The engine is dismantled.
The pulley is removed from it. An adapter coupling must be made under its shaft. On the one hand, it must be put on the shaft, and on the other, it must be equipped with an internal M14 thread.
It is best to grind the sleeve on a lathe. If it is absent, you can cut the M14 thread in the workpiece to half, and screw it onto the grinder. Then the blank is ground on a sanding belt and drilled from the free end. Moreover, it is she who should rotate due to the grinder, the drill itself remains stationary. A clutch made in this way will have a balance that is no worse than that turned on a lathe.
The gearbox is removed from the old grinder. It is necessary to cut its anchor in half, and then release the input shaft.
A sole made of sheet steel is made under the engine. It is installed on it. With the help of a clutch, the secondary shaft of the grinder is connected to it. To mount the gearbox, an adapter plate is made of sheet steel, which is welded to the sole.
The engine is connected via a speed regulator. Now, when starting, the shaft on the gearbox will rotate 3 times faster, which will allow attaching the flexible shaft of the drill. If you connect the gearbox the other way around, then the force will increase 3 times, but the speed will drop.
