DIY electric drill - very simple and fast

And again, Good day to everyone, Dear enthusiasts of home-made devices, tools and other mechanisms.



Today I would like to share with you a simple way of manufacturing a simple, budget-friendly version of manufacturing a mini electric drill.
Then we will consider the identified pros and cons of the resulting product.
The mini drill is widespread and is used to perform an incredibly large volume of tasks in home conditions the garage, in the country or repair.
A mini drill is used for a wide variety of small jobs. In particular, it is used for drilling electric printed circuit boards, a conventional electric drill is completely unsuitable for such work.
A mini drill equipped with special nozzles can very well be used as an engraver, or as a grinding machine or milling cutter. To use it in this quality, special nozzles with a rough working surface are used. In the process, the nozzle processes the part or applies the necessary pattern to the workpiece.
Of course, a miniature drill cannot handle a thick iron, but a hole in a metal sheet up to one millimeter thick will suffice to drill a bit.
Do-it-yourself mini-drill manufacturing options are unimaginable. Everything fits into your flight of imagination, fantasy and is restrained exclusively by the components you have for making a drill.
So your fantasies are limited only by your bins of spare parts.
The heart of any mini drill is a small but powerful electric motor. Also, for the manufacture of our mini drill you will need a collet chuck (a collet chuck is a type of drill chucks. They hold the drill in the drill during the drilling process. The quality of the work of the electric drill depends on the quality of the collet chuck and, accordingly, the attachment of the drill to the electric motor.Therefore, the choice of a collet cartridge should be approached with all responsibility), it is quite problematic to make a collet cartridge on your own at home, so it is better to buy it in a store.
Standard cartridges (with collets for drills with a diameter of 0.5 to 3.2 millimeters) can be found in any online store at an affordable price, the price varies from 100 to 150 Russian rubles.
An important detail of mini drills where all components are located and fastened is the case. There are many options, in our case, a tube from a fan pipe is used, the inner diameter of which, as well as possible, coincides with the outer diameter of the electric motor. When fixed in the housing, the engine stood up almost without gaps.
Connecting electric wires - are selected based on the power of the drill, but due to the fact that we use an electric motor with low power consumption, we select insulated electric wires of a small cross section. For high-quality soldering of the electrical circuit, we will need acid for soldering and tin rods, a soldering iron or connectors.
Almost any beginner enthusiast can assemble a mini drill on his own. It is up to desire and perseverance.
As always, compliance with safety precautions when working with high-risk tools. Work carefully. Observing all safety precautions. Do not taste the electricity with your tongue, do not stick your fingers where the dog does not stick its tail. Before any action, turn on the brain. And then, take a word, each member of your close-knit family, including the dog, will have its own mini drill.

And so we proceed to the manufacture of mini drills.

“It's easy to sit and watch. It's hard to get up and start criticizing. Today we congratulate and reward the person who always acts and criticizes, immensely deeply respected Valeria. The next anniversary year 2020, in honor of such caring critics as Valery, we will call the year of criticism!



Hurray, Comrades !!! ...
Stormy applause !!!
:-)))
Who is the last for medals?

To summarize the discussion!
First place - Ivan_Pokhmelev. On the issue of battery placement.
Second place - Valery. According to the capacitive realities of Chinese batteries.
The rest is trash.
Thanks to everyone!
Nothing complicated: type Alt + 7, get a point in the middle of the line “•", although it is bold, but in the middle.

You're trying to justify even lying

On my keyboard is not so marked.
But it doesn’t matter: they are in different layouts. How could one accidentally switch from Cyrillic to Latin and back if this was not wanted?
Moreover, the designation is not the same point.

Kindergarten, pants on the straps ... catch the skin ... :-)))
Not at all. ((One typo, another - technical illiteracy
"/" and "." are located NOT on one key, but on the neighboring ones, but, unfortunately for you, in a Latin layout. You, in an attempt to justify yourself, even did not succeed in lying properly. Moreover, there is still not the point. If you do not know how to write the abbreviation correctly, write completely "ampere hour" or in Latin letters "Ah".
Or copy from here: Ah ;)

What is this strange unit of measurement "a / h"?

Well, everyone will notice how stuffy you are ... Just "/" and "." are located on the same key and when you click on them, the “keys” sometimes you get typos, throw a stone at me if you don’t have one ... :-)))
Quote: Valery
And explain what is fraught,
Acid corrodes the conductors over time, even if they tried to wash it. If the wire is 1.5 or 2.5, then maybe it will cost (if the acid does not get into the insulation).
Do not solder electronic equipment with tin, do not use soldering acid. Who is engaged in such a perversion, belongs to the category of people who believe that it is possible to hammer nails with a microscope.

You wrote:

yes
And after: If you weren’t taught to wash soldering places after the soldering process (regardless of the type of flux used in this process), I’m sorry for you ...
The designated capacity is maintained only by brands
- I wrote an article about batteries for a long time, there the author closely studied this topic. He said that several branded factories produce batteries (I don’t remember the name, but something like Sony, Panasonic). And if under this brand (original), then everything will be exactly as stated. The rest sell substandard from these factories and there is already what comes across.

A killer argument!)))
You can, of course, and solder with tin and acid. If the end result is not of interest.
Dear, have you read my comment carefully or diagonally? If the second - re-read it again ... It will not reach - again, and so on until complete enlightenment ...
Wrote the same: it is possible to use acid flux, only then a thorough soldering of the soldering place is required ...
Is it so intelligible?
Tin in this case serves only as a solder with a higher melting point (232 degrees against 180 for POS-61)

I strongly doubt that even eminent brands will provide 9.8 Ah in the form factor of 18650!

At the moment, Li-Ion batteries have a specific capacity of up to 240 Wh / kg

Here the rule of the "golden mean" applies)))))

Not so. When ordering something, they ask for the amount that you are ready to pay. Let's say you are interested in a Boeing 747 for 100,000 Russian "dollars". A week later, a Boeing is in your hangar ... made of cardboard, but looks as if it is made of steel and plastic ... :-)))
And explain what is fraught with, please. And then, for example, as a person who rarely picks up a thirty-watt soldering iron, I also like the ends of the wires before tinning, dip in acid.))))
Here the rule of the "golden mean" applies))))). The more incredible the number on the label, the lower the real capacity ...))))
For example, in "9900" I found real 300-400, and in "4000" - already 800-900 !!!
The conclusion suggests itself that the cunning kmtays think: "The more you believe in fairy tales (read: the more you are - a gullible gullible!)))), The more we try the crown nae... mislead!

10 is not 10, but close. The designated capacity is maintained only by brands. Our Chinese friends are big entertainers, this is so ...
Tin is possible. With acid you can’t.

You can solder tin electronics - the only thing, the tin melting temperature is higher than that of PIC ... And you will get soldering with lead-free solder ... Studied at a technical school - we soldered tin in practice ...
Yes, and acid flux can also be used for this - only then thoroughly rinse thoroughly ...
So not everything is so simple ...

There are many things written on the fence.

Literally, it sounds like this: It’s also written on the barn, and there is firewood ...
And the rest you are right ...

To charge each time, pull out the switch?
Why, I slipped the battery into "0", replaced it with a new one! I never understood why the problems with the batteries, really to work in a clean field?
Valery
He, however, before that bought a flash drive for 512 gigabytes. Some teach life nothing ...
I somehow bought mi-sro-SD for a 64 GB camera, the real capacity is 8 GB, but some people don’t learn anything, I bought 16 GB, I thought that they weren’t faked, yeah, right now, 4 GB! Although on the package, and when connected to a computer, everything is fine: 64 GB, 16 GB! dontknow

Yes ... God grant that it contains 10% of what is written ... Moreover, literally, and not figuratively.
... Recently, too, talked with one. He collected the "powerbank", I offered to give him a link to Ali, where I bought 18650 with a capacity of 2600 - and there really was this, roughly, capacity.He then told me that I don’t know how to look for it, just !!! He found on 9000, and even cheaper!)))). I did not take into account my arguments that, they say, if there are so small 9 ampere hours, and so cheap, why then do they not put them on stackers and forklifts ??? Or on boats ???
When they arrived, they checked the real capacity on my "smart charger" ...
From 340 to 680 mAh.)))))
True, he bought a flash drive for 512 gigabytes before that.)))))
Some teach life nothing ...))))
