From the scraps of a plastic pipe for a water supply system and a 12 V motor, you can make a manual grinder, which is useful in a home workshop and garage. The device runs on battery power and has a compact size.
To make this homemade product you will need a piece of plastic pipe and a 90 degree angle, a 12V electric motor, a rechargeable battery, an on / off button, wires for connecting and an adapter to the motor shaft.
First of all, the master puts the adapter on the motor shaft. This adapter is needed to secure the Velcro disc, on which the grinding wheel will later be attached.
The main stages of work
In a plastic pipe, it is necessary to cut a "window" under the on / off button. You can do this with a drill. Then a piece of pipe with a corner will need to be painted. It is better to use paint in the spray can.
Next, the electric motor is placed in a corner, at the other end of which a plastic pipe is inserted. Wires are output through a cut out "window" for the switch.
At the next stage of work, the wires are connected, as well as the installation of the toggle switch and the battery. A cap is put on the end of the pipe. Thus, all components are securely plugged inside.
