Powerful milling machine from the washing machine engine

Milling machines are widely used in furniture production and, since they belong to professional equipment, are not cheap. Among them, the most versatile and widely used is the submersible (vertical or rod) milling cutter, which can be made by itself from the outdated components and parts.

Will need

To make a homemade router, we need to get:

• an electric motor from an old washing machine;
• two front shock absorbers from the "Lada";
• conventional collet chuck for a drill;
• start button;
• a small sheet of thick metal;
• open metal profile and round tube;
• stud, plain nuts and wing nut.

The sequence of manufacture of the milling cutter from the washing machine engine

One of the main components of our homemade product is an electric motor. We check its performance and, making sure that everything is in order with him, we begin to modernize it.
First of all, we grind the grinder on the end of the shaft and grind it to the size of the seat of the cartridge, which was also prepared in advance on a lathe.
The main thing in this operation is to eliminate the runout and a firm fit, which we achieve with a hammer.
To check the quality of the cartridge landing on the shaft, turn on the engine and make sure that it is durable and there is practically no vibration. For reliability, in the future we grab the cartridge by welding to the shaft.
We use unfit automobile shock absorbers as vertical guide rods. To do this, cut off the upper and lower attachment points from them using a grinder.
We prepare on the engine seats for installing and securing shock absorbers using a grinder.
We carry out the rear mounting using a bolt and a reliable washer through a standard hole on the engine, screwing the bolt into the threaded hole of the shock absorber.
Before the final installation of shock absorbers on an electric motor, we drill holes in their bottom and remove oil from their cavity by pulling and lowering the rod several times.
We fix the shock absorbers on the front with a knitting wire, passing them through the pre-drilled holes in the "ears" of the seats on the engine, wrapping it around the shock absorber body, and tying the ends together with pliers.
Taking into account the distance in plan between the shock absorber rods, mark out a thick metal plate, cut it off from the workpiece, remove burrs and process the edges. She will perform the functions of the soles in our homemade router.
In the middle part of the plate with a cutting disc, we make a one-sided rectangular cut commensurate with the diameter of the cartridge and also process it by removing burrs and rounding the edges.
We weld the ends of the shock absorber rods to the sole plate of a symmetrically rectangular hole.
From the back, vertically weld the tube of the required height. On plates loosely bolted to the engine housing above the upper mount of the shock absorbers, we push the open steel profile and cut off the excess. The profile is pressed by the plates to the motor housing for flanging, screwing the bolts.
Above a tube vertically mounted and welded to the sole, we drill a hole in the steel profile.
We insert a stud with a nut in it so that it is under the profile. The lower end of the stud is placed in the tube and lower it to the end of the nut in the end, which is then welded to the end of the tube.
At the end of the stud, screw the wing nut on top of the profile, with which you can adjust the height of the head of a homemade milling cutter above the sole and, thereby, the depth of processing of the material.
To start and stop the engine of our home-made router on the front side, set the on / off button.
For safety, we install and fix an annular casing over the cartridge, which will protect the operator if the cartridge suddenly comes off the motor shaft.
With the help of our home-made milling cutter, you can carry out any operations on wood, up to cutting complex curvilinear shapes, including various signs: letters, numbers, etc.
