With these instructions we show you how to make your own hand drill.

Step 1: Materials

Materials to use.

1. A small motor, running at 5 volts

2. PVC pipe ¾´´

3. PVC stopper, for ¾´´ tube

4. Union for 1´´ tube, this taking into account the dimensions of the motor

5. 2 adapter for tube ¾´´ to 1´´

6. Wire

7. Female connector for source

8. A switch

9. Three pieces of cable 10´´, 7´´ and 3´´

10. Large syringe, avoid that it has been used for medical purposes, if possible it is not used

Step 2: Process

First of all, we are going to extract the motor from an old disused equipment, in our case it was from a rearview mirror, then we will cut the tube de ´´ of a manageable length the size of your hand, for our almost been approximately 5´´.

Then we will take the plug for tubo tube and we will make a hole to put the source connector, we have extracted our source connector from a damaged radio, we soldered two heavy cables, one with 10 '' that would reach one pole of the motor and the other with 3´´, the smallest we take it to one end of the switch and on the other side we have put 7´´ of cable that would go to the other side of the motor.

Before connecting the motor, at the other end of the PVC tube we will put the adapter from ¾´´ to 1´´, after this we will put the union for it had 1´´ now if we connect the motor and we introduce it in the union, then we will put the other adapter, but not before making some cuts to support the motor.
