Hello everyone, in this instruction we will consider a very simple and cheap option for making a home-made drill. Of the most expensive here you can take, perhaps, a motor, but finding it should not be a big deal for you. As for the flexible shaft, it is also homemade here. The flexible shaft is made from ordinary cycling a cable and a piece of hose.
So simple homemade You can carry out various small works. This is cutting, grinding, drilling and much more. In the chuck, you can set the weight of both purchased nozzles and make them do it yourself. So, let's get down to manufacturing.
Materials and tools for homemade:
Materials:
- regular CD-ROM;
- ;
- a piece of PVC pipe;
- 12V motor ();
- ampoule from the gel pen (tube);
- metal rod;
- ;
- super glue;
- a cable from a bicycle;
- electrical tape;
- paint;
- food plastic container;
- a piece of plywood;
- thin sheet metal;
- switch;
- a set of cutting discs;
- power supply and connector for it;
- rubber tube.
Instruments:
- stationery knife;
- glue gun;
- screwdriver;
- drill.
Drill manufacturing process:
Step one. Flexible shaft handle assembly
Let's start with the handle of the flexible shaft, this is the most difficult part of homemade work, however, there is essentially nothing complicated here. The pen consists of two parts, start with the first. In the first part of the handle is a metal axis on which a chuck is mounted. We take a plastic disk or other material and make 3 rounds according to the diameter of the plastic pipes, this will be a kind of plug.
Next, you will need an ampoule from a gel pen or another suitable tube. Its inner diameter should be such that a cable can be easily inserted into it. Drill holes in the plugs along the diameter of the tube and assemble the structure. Everything is going to glue, the author uses superglue.
Now we will need a metal rod, install it inside the first half of the handle. On the one hand we install a chuck, it is fixed with a screw. And on the other hand, with the help of superglue, we fix a piece of plastic tube. As a result, we get an axis that can not jump out back and forth, that is, there are stops at both ends. Here it is advisable to put thrust washers and reduce backlash.
The first part of the handle is ready, you can make the second.It is done in a similar way, only the plug is placed only on one side, and a piece of tube is glued into the plug. You can attach the cable! We draw it through the second part of the handle and apply hot glue to the tip of the cable. Quickly, until the glue has dried, insert the tip of the cable into a tube mounted on a metal axis. You can pinch the edge of the tube with pliers to keep everything secure.
Now glue both halves of the handle with super glue. From above, the author strengthens the junction with the help of electrical tape. The pen is ready! If desired, it can be painted, as the author did.
Step Two Install the engine
To install the engine you will need a piece of plywood, take a motor and fix it to the base with the help of home-made clamps made of thin metal and self-tapping screws. To connect a cable to the motor shaft, fasten a piece of plastic tubing to the shaft.
The engine can be installed in the housing. The author uses a plastic container as a case. It is cheap, convenient and affordable. Before installing the motor, solder the wires to the contacts.
To fix the platform, the author uses hot glue. We put more glue on the plywood and quickly press it to the bottom of the container.
The motor is installed, you can connect the wiring. The electrical circuit consists of a switch, as well as a connector for connecting the power supply. We cut out places for them and set. Solder the wires to the desired contacts.
In conclusion, you need to install another tube opposite the shaft. The author glues it with hot glue on both sides to keep everything secure.
Step Three The final assembly of homemade
Our drill is almost ready, it remains only to connect the two nodes. Here we need a rubber tube, it is desirable that the rubber is not soft, so there will be less friction of the cable. Before assembling, it is highly recommended that the cable be well lubricated with grease, so the efficiency of the device will be higher, and the hose will be wiped much more slowly.
We take the hose, cut off the desired piece and put on the cable. We put one side on the handle, there is a fitting for it from the tube. On the container, we also installed a fitting from the tube. At the end, you will only have to fasten the cable to the motor shaft. We apply hot glue to the tip of the cable and quickly insert it into the tube mounted on the shaft. Clamp the tip of the tube with pliers, so the connection will be several times stronger.
Step Four Testing!
Homemade work can be tested, connect the power supply to 12V and try to turn on the machine. If everything works, try to install the first nozzle. The author has acquired a set of small cutting discs and demonstrates how the machine easily cuts ice cream sticks and even a board. Such a nozzle creates a maximum load on the device, and it withstands it.
In addition to cutting discs, drills with a diameter of 0.5 to 3 mm can be installed in the chuck, which is more than enough for various small jobs. The author also made a grinding head out of a nail and cork. With it, wood, plastic and even metal are perfectly polished. That's all, our homemade drill is ready! I hope you liked the homemade. Good luck and take care!
