We all know from the experience of working in school workshops how easy and convenient the drilling machine is to operate. After all, with its help, you can get holes of the exact diameter strictly at the right angle. And when using an electric drill, the drill often leads to the side. In our article we will tell you how to make a drilling machine from a jack. True, for its manufacture you will also need an engine from an old washing machine, but you can buy it inexpensively in household appliance service workshops.

Materials for manufacturing
In order to make a drilling machine, you will need:
- an engine from an old washing machine with a gearbox and a bushing mounted on one plate;
- mechanical car jack;
- drill chuck;
- metal box of the desired shape and size;
- bolts, nuts, washers;
- marker;
- drilling machine or drill;
- screwdriver or screwdriver;
- welding machine;
- thick metal circle for the bed;
- flywheel.
Step 1 Attach the jack to the mounting plate
We remove the belt from the engine to the gearbox and unscrew the engine from the plate.
With a marker, we outline the places for attaching the jack and drill them.
We outline and drill holes in the thrust sole of the mechanical jack and fasten it to the plate from the outside with bolts, washers and nuts.
We install the engine in place and put on the belt.
Step 2. We connect the cartridge
For convenience in the operation of the machine, the shaft of the gearbox bushing must be slightly lengthened. To do this, we use a bolt on the thread of the cartridge from a drill, the cap of which is welded to the shaft.
We wind the cartridge. For reliable fixation of the cartridge, we use a lock nut.
Step 3. We assemble the machine on the bed
We will use a circle of sufficient diameter made of thick metal as a bed. We weld the jack to the edge of the circle.
For smoother control of the machine, we weld the flywheel to the adjusting screw of the jack.
We install the power button and connect the wires to it.
From above we cover the motor with a casing of a suitable size.
Our jack drilling machine is ready to go.
