Homemade Dremel

According to the master, his analogue of the model of the instrument of a famous brand is not inferior to the original. The statement is controversial, but given the cost (about $ 10) and the implementation of the main task (drilling and grinding), the tool turned out to be not bad. Drill diameter up to 3 mm.




Tools and materials:
-Engine;
Collet chuck;
-Collet;
-Polypropylene 2-inch pipe;
-Rule;
-Marker;
- Canvas for metal;
-Sandpaper;
- fiberglass;
-Drill;
-Drill for wood adjustable ("ballerina");
-Clamp;
-Glue;
- The file is round;
-Calipers;
-Wire;
-Soldering iron;
-Thermotube;
-Lighter;
-Screwdriver;
-Screws;
-Rechargeable batteries;
-Switch;
-Connector;
-Insulation tape;
- Sticky letters;
-Scotch;
-Aerosol spray can with paint;
-Scissors;

Step One: The Case
The author made the case from a polypropylene pipe. Pipe diameter 5 cm, length 15 cm.





I cut two fiberglass plugs at the ends of the pipe. The plugs should be slightly larger than the outer diameter of the pipe. The master immediately stuck one plug.









Step Two: Engine
For his instrument, the author used a 12 V engine, 400 rpm. A collet chuck was mounted on the motor shaft.





I drilled a hole in the center of the shaft for the shaft and two holes for the mounting screws.


Step Three: Batteries
To power the mini drill, the master used two lithium batteries. Two batteries connected in series give out 7.4 V and have a capacity of 2400 mAh. The voltage is certainly less than that required for the engine, but according to the author, it is enough. The author solders the wires to the battery contacts. Fixes batteries with electrical tape.




Step Four: Build
Now you can start assembling. Solder wires to the motor and fasten it with screws to the front end cap. In the case, makes a hole for the switch. Installs it and builds it in the circuit between the battery and the engine. The second plug sets the connector for charging the battery. Connects the connector and the battery with wires. Glues the back cover.

















Step Five: the inscription
So that no one doubts that it is Dremel, the master, with the help of a spray can of paint, adhesive tape and letters, makes an inscription.




The tool is ready, it remains to test it.






The entire manufacturing process can be seen in the video.

Well, he likes to cut one blade.

Reminded ... In childhood, at age 12, he rode a motorcycle to a store with a neighboring village. When I was in the store, a policeman went there. He went out, I waited a bit, I went out ... Oops! Standing near a motorcycle, waiting for me! (I guessed that there was nobody to come except for me!). Asks
- Whose motorcycle?
- Brother!
- All! you got there!
- And where did you get the idea that I was driving ??? I drove it in my hands !! Everywhere I drive myself !!! Even when I go to the toilet, I still drag this motorcycle along !!! I have such a habit !!! And the brother permits! ...

... He looks .... And then there is nothing to say! ))))
True, in revenge, he made sure that I went home (about 4 km) and really dragged the motorcycle in my hands! shok It. True, there was a "Sunrise", but for a 12-year-old boy, but on an engraving ....))))
But I didn’t take it ...))))

Well, he likes to cut one blade. Now I’ll roll another article, where he cuts aluminum tubes with a cloth.

Well, now the master has "Dremel" and he will no longer mock the pipe with a hacksaw blade ...)))))
..And still, even a poor Pindos did not even have a hacksaw ....)))))

Here is the case when it’s not cheaper and doesn’t exceed in some necessary parameters ...

And as for speed - "does not exceed" - too softly said.

And yet ... Often I hear (mainly from Russians) the name "Dremel" as applied to all engravers. Do you have something there, is it already as a common noun?
The first time I encountered a couple of years ago in correspondence with one "techie" ... There was something like this dialogue:

“What did you do with the chamfer?”
- Engraver.
- Dremel?
- No, Boshem! .. But what's the difference? At least Blaukraft, at least Farm! ))))
- In terms of? Do you list the names of Dremel ???

-...... (Here my brains swam!))). The company "Dremel" - it turns out, "Bosch" and others ..! ...))). How to understand this ???? (Well, about Bosch, okay ... The Dremel trademark belongs to him. But Blaucraft with the Farm, what does it have to do with it ??))))
Moreover, at that time I had a cutter from this company .. And I, for example, did not know then that she was releasing engravers ...)))).

Now I have often met a similar one ... I already understand what they mean ... Yes, and I know that they were the first to do it ...
But my first engraver wasn’t "Dozing" at all, and therefore it’s unusual ...

For a lower price on Ali, you can take a similar functional one ... Here, at least:
For about the same - a full-fledged engraver, on which you can install a flexible shaft ...:

The master himself, but ... Here is the case when it’s not cheaper, and doesn’t surpass in some necessary parameters ...
