How to make a mini grinder from available tools

The "Bulgarian" or hand-held circular saw is an excellent tool that will always come in handy on the farm. But this device can hardly be called a pocket one, and it is extremely inconvenient to carry it with you. However, there is a way out - to make a mini-grinder with your own hands.

All necessary spare parts can be selected from unnecessary items. What we need: an iron Coca-Cola cap, a miniature electric motor, a battery, a ballpoint pen refill and a switch.

We fasten the battery, switch and electric motor with hot glue and a pair of wooden sticks. Next, we straighten the iron cover with a hammer and cut out "teeth" on it. We put the resulting cutting disc on a piece of the rod and attach it to the motor axis. That's it - the mini-dremel is ready.
