Assembly instructions for a homemade drill

Method number 1 - The second life of the old tape recorder

As you know, the first version of a homemade mini drill will be made from a time-lost CD recorder. All you need from a former bestseller is a motor that will rotate the chuck with the tool. Since the power of the device comes from 6 Volts, you will additionally have to find the appropriate power supply or several batteries. You can use the usb adapter, however, in this case, the power will decrease slightly. In addition, you need to buy a collet yourself (sold at any radio store or on the market, on the Internet on AliExpress, the price is small) and find a suitable housing for homemade, although this is not necessary, you can hold the tool directly by the motor.

So, in order to independently make a mini drill from a motor at home, you must follow these steps:

1. Solder two flexible wiring to the device contacts, as shown in the photo.
2. Install a drill bit of suitable size in the collet.
3. 3. Put the finished nozzle on the motor shaft, and fasten the cartridge with screws. We draw your attention to the fact that the collet hole should ideally fit the shaft diameter, which is usually 1.5 or 2.3 mm. Otherwise, it will be difficult for you to remove the vibration when working with a homemade small drill. If the hole in the collet chuck turned out to be larger than the motor shaft, then you can try to rewind several layers of adhesive tape, thick paper, polyethylene or other material. This compensates for clearance and reduces vibrations.
   
4. Gently tighten all 4 bolts on the nozzle, then connect the wires to the power source and experience the finished home-made. For ease of use, it is advisable to add a button or switch to the power gap.
   

That's the whole do-it-yourself device assembly technology. As you can see, making a microdrill from a motor is not at all difficult, even for a novice electrician. 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 break immediately, so be careful and buy a few drills in reserve for training.

A very important point that you should be aware of is that in order for the drill to spin in the other direction, just swap the wires! An interesting video instruction on how to make a simple drill, you can see below:

Method number 2 - The coil in the course!

Another original way to make a mini drill at home is using a fishing reel. In this case, the assembly technology is quite simple, but the principle of operation will already be based on mechanical rotation, you will get a hand-held mini-drill

To make a device with your own hands, you will need:

• inertialess coil;
• a chuck from an old drill or a collet of a suitable size;
• hot melt or cold welding;
• a drill.

The assembly process is quite simple and consists of only two stages. The first step is to dismantle the spool with fishing line and cut off the remaining excess axis. After that, the cartridge is glued to the remaining stem. You can do without a cartridge and install a collet instead.When the glue hardens, you can check the finished mini drill. You can see all the details of the assembly in this video example:

Method number 3 - The idea with an antiperspirant

Well, the last version of a homemade mini drill, which we would like to provide readers my.electricianexp - using a cassette motor and antiperspirant containers. The advantage of this model is that it is controlled by a separate on / off button and has a convenient housing. Such a homemade product will be powered by a conventional power supply, which must be selected based on the characteristics of the motor.

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

• motor from a tape recorder;
• suitable collet with a drill;
• used antiperspirant;
• RCA jack for power and a mate for it;
• Power Supply;
• switch from an old carry.

First of all, you need to make a mini drill according to the instructions provided at the very beginning: put the collet on the shaft and fasten it with bolts. Next, the motor housing is installed in an antiperspirant. As you can see from the photo, the dimensions were perfect for installing the part. If the motor has free running inside the housing, secure it with electrical tape and hot glue.

After that, in the top cover you need to drill a hole for the outlet of the collet or the drill itself. At the same time, in the bottom you need to make a hole for the power connector. Using a stationery knife, it is also necessary to cut a window under the switch, then solder all the elements of the chain in series and install them in a convenient place for you.
