How to make a mini grinder do it yourself

First you need to find polystyrene to prepare the basis for the device. After that, you need to cut a hole to install a switch in it. Then you need an electrical tape and a power source, for example, the well-known Kron battery. We wind the power battery (Krona) to the foam base with electrical tape. Take the champagne cork and the handle rod. We cut the rod to the desired length, then put the handle rod on the cork with a blunt end and insert the point of the rod into the hole for the motor shaft. After that, you need to cut a strip of abrasive tape under the cork’s dimensions with scissors. After you have cut the ribbon, stick it on the cork around the circumference. This construction of cork will be the working part of the machine. Carefully inspect all the wires and connect them with twists, isolate the connections with electrical tape. We try to start the resulting device. Now you have your own mini machine. Such a device is useful for performing simple minor work for which a conventional grinding machine will be too large and inconvenient. If you are an observant and patient, as well as assiduous person, it’s not difficult to make a grinding machine yourself. For this you need only dexterous hands and a little patience.
