Instructions for assembling a self-made drill

Method number 1 - Second life of the old tape recorder

As you understand, the first version of the homemade mini drill will be made from a time-forgotten CD recorder. All you need from the former hit of sales is the motor that will rotate the drill. Since the device is powered by 6 volts, you will additionally have to find a suitable power supply or battery. In addition, you need to buy the collet yourself( sold in any radio store, the price is small) and find a suitable housing for the homemade.

So, in order to independently make a mini drill from the motor at home, you must perform the following actions:

1. To the device's contacts solder two wires, as shown in the photo.
2. Place a suitable size drill in the collet.
3. Set the nozzle on the shaft of the motor, which will rotate. We draw your attention to the fact that the hole of the collet should ideally fit the diameter of the shaft, which is usually 1.5 or 2.3 mm. Otherwise, it will be difficult for you to remove vibration when working with a self-made small drill.
4. All 4 screws on the attachment carefully pull, then connect the wires to the power source and try the finished self-made.

That's the whole technology of assembling the device with your own hands. As you can see, it is not difficult to make a microdrill from an engine, even an electrician-beginner. The only drawback of such a device is the small strength of a thin drill. If you drill holes not at right angles, it will immediately break.

A very important point that you should know about - to turn the drill in the opposite direction, just change the wires in places! An interesting video instruction on how to make a simple drill was provided by Roman Ursu on his video blog page:

Method number 2 - Coil in the course!

Another original way to make a mini drill at home - using a coil from a fishing rod. In this case, the assembly technology is quite simple, but the principle of operation itself will already be based not on electric motor performance, but on mechanical rotation, as a small drill.

To manufacture the device yourself you will need:

• inertia-free coil;
• cartridge from an old drill or collet;
• hot melt or cold welding;
• drill.

The build process is fairly simple and consists of only two steps. The first thing to do is to dismantle the spool with a fishing line and cut off the remaining axis. After that, the cartridge is glued to the remaining rod. You can do without a cartridge and install the collet by yourself. When the glue is solid, you can check the finished mini dental drill. See all the details of the assembly you can on this video example:

Method number 3 - Idea with antiperspirant

Well, the last version of the homemade mini drill, which we would like to provide readers themselves Electrician - using a cassette motor and capacity from an antiperspirant. The advantage of this model is that it will be controlled separately by the on / off button and at the same time recharged from the conventional power supply.

So, first you will need to prepare the following materials:

• the motor from the tape recorder;
• suitable collet with a drill;
• used antiperspirant;
• socket RCA for power connection;
• switch from old carrying.

After that, in the top cover, you need to drill a hole for the collet outlet or the drill bit itself. At the same time in the bottom you need to make a hole on the output of the power cord from the motor. Using a clerical knife, you must also cut the window under the switch, and then solder all the elements of the chain.

The advantage of this version of the homemade mini drill is its convenient handling, small size and at the same time stylish appearance. It is recommended at home to do this option, the more from the tools at home you can find everything!
