Manual mini electric drill







Somehow I needed to drill a board for radio components. Screwdriver, drill too large. I thought and decided to assemble a small drill from what is.

Materials

1. I set the electric motor D-2RT or DPR-52-N1-07A
2. I have a 15V 0.8A power supply from an old tape recorder
3. collet chuck and replaceable collet had to buy
4. limit switch

Tool

1. soldering iron
2. screwdriver

I did not want to be too tricky, and I connected the trailer to the motor with adhesive tape. The motor soldered wires - trailer - power supply. Then set the collet chuck.

And all I have a small drill that can not only drill, but also works with the devices of the engraving set. With a 3mm drill I drilled about 1cm of aluminum, there is nothing to say about wood. For small jobs more than satisfied.



I tried for the first time my simplest homemade publish that works a couple of years.

We need to learn how to publish next time.
