Hello to you, dear readers and the inhabitants of our site! This article will be useful for everyone involved in small products and homemade products. For delicate work, you often need a special tool. In it, Vladimir Natynchik, the author of the YouTube channel of the same name, will show how he made a dremel from an old blender. Using this tool, engraving, drilling and grinding work can be performed.

For this homemade product you will not need a complicated tool, but it will take about half an hour. True, you have to get something from the materials.

Instrumentsused by the author.
- Hacksaw
- glue gun
- soldering iron
- pliers
- Cable stripper
- Side cutters.

Materials
- Old blender
- Mini cartridge with adapter sleeve 5 mm
- Dimmer
- Plastic mounting box
- solder
- Insulation tape.

Manufacturing process.
An ordinary brand dremel looks like this.

Vladimir had such a blender; he doesn’t even have a speed regulator on it.



With the help of a hacksaw, it cuts off excess body elements.


Using ordinary pliers, removes the standard coupling.



Measures the diameter of the motor shaft - it turns out 5 mm.


Disassembles the case and fills the part from the power button with hot glue.


The button itself is also removed from the board with pliers, although it could have been removed.



He cuts off the excess contacts from the button with side cutters, seals them shortly. A button is also not needed, the instrument will be controlled through an external unit.





Here is the kit that Vladimir bought. This is a mini cartridge and a 5 mm adapter sleeve.

Puts the coupling on the motor shaft, clamps it with an Allen key.




And then puts a cartridge on it.



The key for the cartridge is wrapped with electrical tape to the power cable, so as not to lose.

Bites a wire in a convenient distance.

Disassembles the mounting box. On its cover marks with a pencil the required hole, and cuts it out.






Dismantles the case of the dimmer, installs it in the lid, and fixes it with screws with a press washer.






Stripping wires.




Turns them into a mounting box, solders the connection.



Connects a dimmer.


Closes the box, assembles the dimmer body, snaps the lid.




And, cheers, it worked the first time. Revolutions are regulated normally.


And this is how a simple cutter copes with a piece of wood.


Thanks to Vladimir for an interesting homemade product. The decision is really not bad.Of course, for professional dremel, the number of revolutions per minute reaches 35 thousand, and for a blender - about 20 thousand. But also quite normal.

All the good tools!

But is this not for all those bought?
I will not say for sure, but at the time of purchase (not long ago it was) not at all, I specifically chose it with a flexible shaft.

"Bunny"
Are you blue? then everything is clear.
Inadequate dove with megalomania-))) And what did you decide? Lattice has grown? Three people gathered and each suggested its own name-))) And as for the Indians and Amer of the site, so here you were crucified about the incorrectness of the translation, but you yourself offer it is not clear what. So go how you train on bunnies, doves.

Any parallelepiped larger than a matchbox is SAFE!
I completely agree with you, it is a pity that you can not put more than one "+"! But what about the brick? smile

Well, still sort of decided?
Bunny, do not be angry, there will be wrinkles.
Any parallelepiped larger than a matchbox is SAFE!
All that you can clamp the drill, cutter or emery - Dremel!

And you, of course, are a highly experienced interpreter and a clerk from God.
I tremble reverently, and I beat my forehead before your bright eyes.

Those. Chinese bullshit Dremel can be called, and the box can not be a safe? And what is the crap in horseradish? Where in the text of the original article written by an Indian and posted on an American resource is the Russian word casket mentioned at least once? Translation difficulties? Or megalomania?

My small Proksson will be 15 years old, if not more. About the middle, too, then was in the know.
And about generalization generally tin. In the next branch, the author called the plastic box a safe. So damn it, they could not convince the seasoned scribbler (almost pizza from the statues scribbled), which exaggerates a hefty amount. Crowd argue tired.
It’s like shaving a piglet - there’s not much use, but a lot of squealing.
So everything that clamps burs and drills is a dremel. xaxa

Just now the word "Dremel" has become a household word in relation to medium-sized drills.


Yes, I recently realized this ... It's just that we (Belarus) do not call it that ... Perhaps because the engravers we have been selling for a very long time, namely "Dremel" appeared recently. (We generally have a different line of manufacturers. I recently talked about this here.)
So I was recently surprised that in Russia there are no Devolts,, Makit, at worst, Watts and other cheap Blaukraffts and Enhel, but all along, they were Dremel .. .
They explained to me that all the engravers call it with you there ...))))

And I have a flexible shaft and a tripod for hanging the machine itself.

But is this not for all those bought?

Well father, forgive me of the sinner. I'm not talking about brand Dremel, but his Chinese clone.
Just now the word "Dremel" has become a household word in relation to medium-sized drills.
Just like when it became with the words "Xerox" or "Foam rubber".

And it’s more convenient for me to remove a chamfer from a furniture board with a milling cutter!))). I have no dremel. But there is an engraver (I don’t remember the manufacturer. Cheap. Tolley "Farms", Tolley "Blaukraft", Tolley still some "Skill"))). Weak ... Watt 200-300. But, nevertheless, using it "directly" is difficult. Therefore, in 90% of cases it is used with a flexible shaft ...
(True, it is mainly used with cutting discs for metal (for cutting bevels for dowels and other things), or with diamond for cutting bottles and other glass and ceramics ... And, nevertheless, it is more convenient for me with a flexible shaft.)

When you try to do small work compact Proxxon. you will understand that a flexible shaft is a compromise.
I have a Proxxon bought long ago, and my colleague has Dremel (Chinese). Both are good, but each for their own purposes.
Dremel to remove the chamfer from the furniture board - song! A Proxxon-ohm window in plexiglass cut with a minimum gap and exactly the contour - it is. dance

I agree, the homemade product deserves approval, but I'm lazy, I bought a finished one, in a case.
For small works it is inconvenient.
And I have a flexible shaft and a tripod for hanging the machine itself.

For example, I have such boxes - a bucket is lying around. Nowhere to go.
Unless you have to buy a cartridge, and I will grind the coupling from a friend.
The funny thing is - my blender gives out 22K revolutions, the regular regulator.
So, it remains on the turning to process the nozzle, cutting it by a third. And already put on it a bearing and a sleeve with a cartridge.

I like this craft. The fact that good electrical products continue to be beneficial.
But financial calculation is a little frustrating.
A purchased dremel (which is in the picture) costs about 3,000 rubles. In a case, with a bunch of emery, stones and nozzles.
For homemade work - a dimmer - 1000 rubles, a cartridge - 500 rubles, a box - 100-150 rubles.
It's a shame however.
Nevertheless, the craft is like an author plus.

Not only a shortage of money !. as well as the presence of unused equipment. Here I need a dremel once a year. And the blender is lying in the old barn. and what, toad does not allow to throw out - and so will be useful.
Here's the first thing to do with Nintendo - I won’t put my mind =)))

I wrote - MAXIMUM revolutions reach such values. shok

The idea is pretty good. But perhaps applicable in conditions of severe shortage of money. And unsuitable for small work.
Small jobs require a lighter and smaller tool, with a comfortable grip with three fingers close to the micropartridge.
The above-mentioned purchased “Dremel” I used in the manufacture of the TV case. For small works it is inconvenient. The hand gets tired very quickly. Severe, fingers in about 5 minutes cramp.
For medium-sized jobs, when you don’t need to hold like a fountain pen, it’s quite suitable.
About 20 and 35 thousand revs neighing.
What are you going to handle at such speeds? And what tool? At much smaller values, cutters and pebbles become clogged and smoked. xaxa
