Motor from a washing machine does not stop under load, which allows to work with bits with strong pressure.

The manufacturing process engraver
The main difficulty lies in the manufacture of boxes for the engine. It needs to be sturdy and heavy enough that the machine did not jump on the table. For its production need to use sheet steel of 2 mm. First cut 2 of the side wall of the box. To them are welded on 2 nuts so that it was possible for them to bolt the eyelets in the housing. In one side is drilled a hole for the motor shaft.
Then cut and welded the top and the remaining 2 of the side wall of the box. For beauty boxes, the side walls and the top should already be enough to leave a gap a couple of inches. In this case, the angle can be brewed stripes, so it is rounded. At the top of the box you can make perforations. This will allow you to store the hole cutter.
To weight of the machine bottom is made of sheet steel 4 mm. the device will run through embeds. This thick strip is cut 4 blanks to 5 cm Below the corners of the box apertures. Through them need to be screwed down mortgages, which also made holes and threaded. The bottom joins the cast with screws in the same way.
To install the flexible shaft need to drill a hole in the shaft of the engine. So it will not warp, drilling should be on a running motor. Also the shaft is the hole on the side, and it is threaded to tighten tight the cable screw.
To close the connection shafts may be carved on a lathe bushing and weld it to the box. On the side it is the hole to have access to the clamping screw.
If you want to bring the box in the ideal, it is possible to poshpatlevat its walls that would be required if the welding metal bit took.
Then on the side of the output shaft in the box is cut a window for the installation of the speed controller. Also from the pipe need to make a handle for carrying the machine.
The box is stained, varnished, if necessary, if the paint has poor durability. Then installed the motor, ESC, handle, shaft, top boxes bolted clips to the holder.
The screws are drawing the bottom of the legs are mounted with rubber shock absorbers.
