Nozzle - boron screwdriver machine


Hello!
Some small and delicate projects are impossible bor machine, but not everyone can afford to buy it for amateur business.
In this article I will tell you how to make a drill, a nozzle for a screwdriver from improvised materials and I will be pleased if my idea is useful to you.



Materials and tools:

- 2 bearings from inertia reels
- valve from the truck’s wheel chamber
- screws for nut 10
- cap nut 10
- bicycle brake cable
- plastic pipe for hot water at 20
- screwdriver
- hacksaw
- file
- soldering iron


And so, let's start with the most complex mechanism of this device, namely with the tip.

For him, we need two bearings from inertialess coils. I saw similar bearings on sale bearings in a shop of radio details. I did not buy them, because I had available broken coils.

And as a shaft for the bearings, I used a brass valve from the truck’s wheel chamber.

Cutting off the excess

we clamp the future shaft in the chuck of a screwdriver and rotating it, file the necks for bearings with a file.


After this, you need to make a crimping mechanism for nozzles or collets. To do this, I decided to drill a screw suitable for the nut by 10. Having fixed the screw itself in the chuck of a screwdriver, and setting the drill 2.5 mm in another, or rotating the screw in a vice, drill it along the axis.



We cut off the screw head and carefully, in the center, make four axial cuts with a depth of 4-5 mm, thereby dividing the end of the part into four parts. If you allow the slightest displacement by making slits or holes, then the clamping jaws will be different, in the future the nozzles will vibrate and the use of such a drill will be difficult.


Having set the workpiece with the shank in the chuck of a screwdriver, file the head under the cone with a file.

Then we unfold the workpiece by fixing a 12 mm rod with the conical part in the screwdriver's chuck, grind the thread of the shank, thereby reducing the diameter of the part to 5 mm.And on the shaft itself, we increase the internal diameter with a drill of 5 mm, deepening it by about 2 centimeters.


We insert the part into the shaft and drill it with a 2.5 mm drill, pin it with a nail that is suitable for the diameter of the hole, fastening them together.

For the second part of the crimping mechanism, I decided to use a steel cap or blind nut at 10. I could not find such a nut on sale and I had to unscrew it from the door handle from a metal profile.
Nozzle - boron screwdriver machine

To make a hole exactly in the center of the nut, I drilled another screw and tightly screwed the screw in the nut, drilled a hole in it with the same drill.

Then, measuring the end of the crimping mechanism, using a 4 mm drill, enlarged the hole in the nut and, with a 5 mm drill, removed the chamfer from the inside.

As a flexible sleeve of a car bur, I used a bicycle brake cable. Rotating in a shirt, the cable will transfer the kinetic energy of the screwdriver to the tip.
By the way, the nut from the brake system is not suitable for the collet head. The walls of the cap are too thin for this.

Now you need to connect the cable to the shaft. For this purpose, I drilled another screw, only this time, with a smaller diameter and a long one.
Having measured the thickness of the cable, we drill a screw with a 1.5 mm drill and cut off the cap and reduce the diameter of the rod in the same way.

Then solder the cable into the rod about half its depth. For soldering, I used soldering acid and tin solder. We heat the rod with a burner or on a gas stove and solder the cable.

We mark the drilling point and make holes on the shaft, and then in the shaft by installing it in the shaft. After, we pin, fastening the parts together.

Reinforced plastic pipe 20 was perfect for the housing. The pipe length is the distance from one to the second edge of the bearing

Slightly removing the chamfer from the plastic tube we press in the rear bearing. And then passing the cable through it and installing the shaft in it, we press in the front one as well until the play between the shaft and the bearings disappears.

Now you need to fasten the cable jacket to the body of the tip. To do this, cut off a plastic tube 2 centimeters long and make a core for it from a wooden bar. Having made a wooden blank with a diameter slightly larger than the inner diameter of the tube and a length of about 1.5 centimeters, we press it into the tube.
In the center of the core we drill a hole with a slightly smaller diameter of the cable jacket coupling and fix it in it.

Having folded both parts of the case, we mark the places for their fastening among themselves. According to the marks, drill a hole of 1.5, drill about 5 mm deep and from a suitable nail in diameter, make a fastening pin about 1 cm long.

After inserting the pin into one of the holes, we connect both parts, mark from the back of the case and do the same operation for the second fastening.

Having lubricated the bearings and the cable, we finally fasten both parts of the housing.

I completely forgot about the shaft stopper hole, without it it would be impossible to fix the nozzles.
Drill 2.5 drill the housing, and then the shaft. After that, I had to knock out the bearings, clean them of chips and repeat the assembly operation. Fortunately, it did not take more than five minutes.

On the back of the cable, cut off the excess length. So that the end of the cable does not shag, solder it before trimming.
In order to avoid kink and damage to the cable, we assemble the frame for the screwdriver.


Well, for control, we make a simple pedal.

Of course, you could connect the pedal to the start button, but my screwdriver is not cordless and therefore I decided that it would be easier for me to make the pedal with a socket. And on the screwdriver itself just fixed the button.

If anyone does not have an electric motor lying around, then of course you can make a full-fledged boron machine.

Well, that’s probably all. I wish good luck to all home masters and masters in their creative endeavor.

I watched this “discus” for a long time, without interfering. I think this can be finished - everyone expressed their opinion, got to know each other.

I propose to forget all the offensive words addressed to you and start from scratch, communicating on positive notes, without going personal; helping each other with tips, correcting mistakes and shortcomings in designs, etc.
blush Yes, these are passions, directly “fighting” battles of minds and opinions. And after all, everyone knows that how many people - so many opinions. But each prove their case. The worst thing is when they transfer to the person from the product, hang labels on the person, give (think out) him a characterization of his abilities.
How has it already happened that the products presented by the author (and a complete trinket made by crooked hands) are discussed very vigorously? Is it not because it is "yours" "native" and you know all about it? And no matter what and how, the main “shit” is native, with a “native smell”.
But even if so, why such a reaction to a different opinion? Start each with yourself, where is your work in person? As she wrote "a lot of mind is not necessary", so a lot of mind is not necessary to "tear apart" other people's posts and put them here. At the same time, there is not enough mind to choose a decent one.
"This is my opinion and it doesn’t matter to you what you think about it." - not my saying.
In the subject of the photo, according to the latest news ...
And not "about me"?
PS. I deleted ... I hope you managed to read it? ... blush
You know how to do it better, tell me without "bending your fingers", you doubt self-made ask without ambition.

That's it!!!! And instead, in order to CONSTRUCTIVELY point out the flaws, they immediately yell "Nonsense", and vice versa, many, if you indicate them, instead of discussing, begin to be offended ....
I expressed my personal (subjective) opinion on this homemade product and that’s it. Don't I have the right to express my opinion when discussing an article?

You expressed it in a rude manner. They called self-made nonsense. And sarcastically mocked the author .... This is the "trolling"
writes that I have - (quote) "the hands are not very properly sharpened"
I wrote, "IF your hands are not particularly sharpened (you can’t do this), you don’t have to say that this is impossible in principle !!! Moreover, in such a categorical form!
well and of course did not forget to praise myselfas he "made home-made collet clamps back in the USSR, because they couldn’t be bought then. And he did it like that - he drilled a static drill with the Alesya drill and then cut it with a hacksaw blade.
And then clamped a 1mm drill into them and worked. And the drill did not break ...
Where exactly in this quote I PRAISED MYSELF ???
blush If you see the boast that I can perform this not very difficult operation, then I submit your self-esteem ..... And what do you do on this site, if you can’t even do this?)))))) .. . Ahhhh! You just didn’t try? ... Well then, why joke on those who did?
and that he could (quote) "eloquently and rudely, negatively respond to my work. But, his upbringing does not allow this,"

Does it hurt your eyes from resentment?)))). I'd like to be offended, you don’t see who wrote what? : neutral_face:
Well, what can I say? Yes, the "flag in his hands" and the pen is still somewhere

It's not as rude as "If your hands are sharpened incorrectly ...."? Not?
So why the hell did he start to groan my homemade products and
Where?
Again I just want to be offended and are looking for what?
but I did not ask for his advice and evaluation of my homemade products.

Did I give it? ... Where? ...
.... Come, Masha, already cry just like that, since you really want to be offended ... blush
Why do you look, like a schoolboy, at all the comments “against you” through some prism of “insults” ....?
On this site, we all registered not to measure the length and thickness of our ... homemade products.

Where do these complexes come from? No one except YOU thought about it ...
You sing along. It’s clear, “the cuckoo praises the rooster for praising the cuckoo” - these are not my words.

And I praised the author of the topic ???? No !!! You just think primitively: "If you didn’t scold, then you praised!"
And meanwhile, I expressed both approval by the design and criticism about the materials ...
And did it OBJECTIVELY !!! I don’t have emotions like yours ...
and you "made a bunch of machines (which I somehow didn’t see in your homemade products) and mechanisms and built several houses with your own hands (which, in general, are also not there."

.... How did it hook you !!! Mentioned twice ...
..... I do not know if this is displayed in the profile, but I have been on this forum for less than a year !!! And published only what he did during this time !!! In my opinion, this is natural - everything that I did before, I did not take pictures in stages ... Yes, and why ??? ... Why post everything? Kopeks from the site is not my goal - I earn by other methods ... What else is the reason? .... Show off? ... Sorry, sir, I have long left school age ... Ask Delausam why he does not lay out a concrete mixer, for example, or a wood splitter ... Yes, because he doesn’t need this !! He is not going to prove his worth to anyone ....
... You were so offended that I publicly voiced my confidence that you did not work much with iron? So I'm sure of it ....
... And why then are you in such a rude manner to "carry" homemade products from that sphere that you don’t understand? ... (And I’m sure, I’ll repeat, according to your statements, that you are holding a Bulgarian / engraver / drill in your hands, then 10-20 times in a lifetime ...)
And in the end, you write complete nonsense about working with a screwdriver, and even presenting it with a large applomb !!! (Or did you really clamp the engraver's snap into a screwdriver ???).
It was possible to formulate in the form of a question, since you do not know ...
As someone (I don’t remember who) said the right to harsh criticism must be earned ...
P.S. And finally, about my sarcasm, when I called you for the first time a schoolboy ....
... Once I looked at the page with your "micro-fan" and it was then that I smiled with nostalgia: once upon a time I was making a "pocket fan" ... True, I took a motor from a toy machine (then there were no helicopters). The bottom line was that you can get a fan out of your pocket, press a button and cool yourself with a stream of air ... In short, a non-functional thing, but then I was 10-11 years old and I was proud of it ... And then "went further"
And then a man who is still at that stage is trying to "bite my heel", accusing me of "I am doing" rubbish with my clumsy hands and claiming that it works great and singing about my ingenious creation.
You know, you would be offended ... And I (honestly !!!) except for laughter, it did not cause anything ....
Dear Mikhail: 1) about trolling you should not be treated 2) You undoubtedly have the right to express your opinion, but it turned out a little rude to you.
The master does as he can and from what is, disagree, express an opinion, argue, but what kind of dialogue can be if the opinion is expressed in this form. Looking through other home-made sites, I noticed that on most sites they are discussing, looking for solutions to how to make home-made things even better. Everything is sliding in us. Therefore, I am against empty criticism. You know how to do it better, tell me without "bending your fingers", you doubt self-made ask without ambition. I have already said that any homemade product from this (and not only from this) site can be "torn to pieces." And the ideas are not new, and the execution is not perfect, etc. , but here is a homemade site, not a "Silicon Valley".
Valery, I didn’t contact you. Have a rest.
Dear Troll (based on your definition) ... I'm still here, and despite the fatigue, I will answer your last throw ...
Why so impudently ascribe other people's words to me? Even if I agree with them ... But I didn’t say that ...
It's dirty somehow ...
PS. Go to sleep - TOMORROW AT SCHOOL ... (I'm not talking about physical ... age, I'm talking about insults ... About primitive methods of snarling (bias) ...
I passed this stage in school ...
Dear Alexey (pogranec), you will understand for yourself what “Trolling” means.So - this (quote from the Internet) is "posting provocative, inflammatory messages on the network, aimed at inciting conflict among members of a community or bullying, ridiculing a certain subject. The main purpose of trolling is the conclusion to negative emotions." Could you please delve into the situation regarding the discussion of the article "Nozzle - a boring machine for a screwdriver", because of which the whole cheeseboard is.
I expressed my personal (subjective) opinion on this homemade product and that’s it. Don't I have the right to express my opinion when discussing an article?
Understand, I didn’t want to offend anyone. I just expressed my opinion.
And here is what happens next.
The esteemed master Valery, who, in his words, "made a bunch of machine tools and mechanisms and built several houses on his own ....", after my comment he writes that I have - (quote) "my hands are not very properly sharpened" and that he could (quote) "eloquently and rudely, negatively respond to my work. But, his upbringing does not allow him to do this", and, of course, did not forget to praise himself, as he "did home-made collet clamps back in the USSR, because they couldn’t be bought back then, and did it like that - drilled with a static drill, rotate I drilled the workpiece with an Alesya drill, and then cut it through with a hacksaw blade.
And then clamped a 1mm drill into them and worked. And the drill did not break ... ", and even as" recently, one of his acquaintances laughed publicly when she said that a "grinder" can be used to sharpen a quality drill for metal ... I had to grind a broken drill with it .... Doesn’t laugh anymore .... ". Well, what can I say? Yes, the" flag in his hands "and the pen is still somewhere else. So, dear pogranec, based on the foregoing, think again who is trolling whom.
Nobody discussed his work. (Honestly, I think, because they are of no interest to anyone). So why the hell did he start to groan my homemade products and my abilities. I personally know what I'm capable of. I will need advice, I will turn to the most competent masters through this site, but I did not ask for his advice and evaluation of my homemade products. My homemade products were rated by participants and visitors to this site by the number of pluses.
Think, so who is trolling whom?
Sincerely, Mikhail.
I will definitely answer you tomorrow ... Today I am very tired ...
I’ll just say ... If there are grandchildren, don’t act like a touchy schoolboy .. Nobody attacks you and snarls you all the more ... You don’t only have to confidently assert what you don’t understand, and when it is refuted, how to try a schoolboy bite someone "for the heel" ....

Maybe than to look for logs look for a speck? Criticism is constructive, but there is such "because it will not work." Jump from branch to branch and troll all homemade a lot of mind is not needed.

You feel it in abundance.
I’ll also insert my five cents.
This is not a bauble - it is an absolutely useless bauble. It will not perform the functions desired by the Author, because it's a complete bullshit.
This is not bullshit? What is this for? Flies to cool? .....
Excuse me, but what's the idea?
..And here is the idea? And so you can make out all the homemade products. Maybe than to look for logs look for a speck? Criticism is constructive, but there is such "because it will not work." It’s not necessary to jump from branch to branch and troll all the home-made minds.

And about the school - my senior grandson this year went to 9th grade.

blush You are lucky, but I went to school in grade 1 with my great-grandson. And the youngest daughter is in grade 7.
Valery, I don’t understand why you snap back at the comments. Personally, no one offended you. On this site, we all registered not to measure the length and thickness of our ... homemade products. It seems that you are offended by something, as shuhratix said. You see how he sings along with you. And in clause 3 you are not with clumsy hands, you are singing along. It’s clear, “the cuckoo praises the rooster for praising the cuckoo” - these are not my words.
I also saw your homemade products and, you know, I’ll say, they did not impress me, becauseYou work in a different field, our interests and opportunities do not overlap. I’m making shit out of candy, and you “made a bunch of machines (which I didn’t see in your homemade products for some reason) and mechanisms and built several houses with your own hands (which, in general, are also not there.” I do not advise you to put yourself above others I am sure this is not what you are striving for.
And about the school - my senior grandson this year went to 9th grade.
Only women and children are offended.))))).

blush Well, why are you like this? A person is already offended, and you also add kerosene ... blush
An example about a grinder ... you can grind a drill with a grinder, but you cannot grind it properly. In general, the grinder is a fairly versatile tool, in skilled hands.

This is generally my favorite tool ... I sincerely do not understand how I used to do without it ... You can do it with a huge number of operations both on metal and wood ...
..P.S. And I can sharpen drills correctly, believe me ... smile
blush I do not argue!!! I recognized myself in paragraph 3. : smiley: Indeed, in order not to get there, you need to make at least one micro-fan, or a mini-grinder ....: relieved: This will really be a brilliant creation !!!!
.... And in my whole life I just set up a bunch of machine tools and mechanisms and built several houses with my own hands .... Besides, with clumsy hands I can make collet clips with a terrible beating .... blush
P.S. I’m sorry that I’m taking your time ... You will soon be at school ...
To business, I absolutely agree with you.
I don’t want to answer Valery, because I think that he is one of those whom you are talking about in paragraph 3 of your last comment.
Regards, MNS1961.
Valery, you too do not go too far. "East is a delicate matter". I can give you a lot of examples in the opposite direction.
1. You can have a bunch of tools and not be able to use them (or use them primitively).
2. Having read the Internet, imagine yourself a cool "delaput", while not creating anything with your own hands.
3. Make “nonsense” with your clumsy hands and say how great it works and sing your ingenious creation. In this case, there are "singers" compassionate, so as not to offend the author. Causing him only harm and he will not learn to do practical and beautiful.
4. In general, do nothing (not a single publication of your own), and at the same time stick your nose and relying on "somewhere I heard or saw something, but did not understand."
An example about a grinder... you can sharpen the drill with a grinder, but you can not be able to sharpen it correctly. In general, the grinder is a fairly versatile tool, in skilled hands.
This is my general reasoning and does not concern just anyone personally (if he himself does not think of it).

In addition, I also learned a lot about myself.
.

For instance?
.... Or do you want to refute my claim that you did not work much with a file, a vice, a hacksaw, and other screwdrivers and grinders? )))). And the engraver did not hold in their hands ...
... So you are in vain, my friend.))))) .. This is noticeable by the fact that you do not know the little things that are not visible theoretically ....
... P.S. Recently, one of my acquaintances laughed in public when I said that with a “grinder” you can sharpen a drill bit for metal ... I had to grind a broken drill with it .... Doesn’t laugh anymore ....)))))))
I am very glad that my review aroused such interest among the Cool Masters. In addition, I also learned a lot about myself.
Regards, MNS1961.
For you, Delausam, and for me this is not an idea. And for many young people and beginners - hoo, what an idea ...)))). Recently, one “student” was delighted when I showed him that by fixing the drill on a clamp, you can do it emery ... Although this is certainly not an idea ...)))))
The author has developed a completely viable and functional design.And performed quite professionally. Simply, due to the choice of materials and components, its resource leaves much to be desired ....
By the way, the polypropylene handle with which you jogged so clearly will survive the bearings installed in it ...
you need to have a screwdriver in which to simply insert the blue-white boron (in the last photo) and do what you need, the author was just "zapadlo", because he is not looking for easy ways.

But after this phrase, I realized that you yourself did little at all with your hands ... In the best case, you collected something from the finished nodes ...
Because I have a factory engraver. It can work with or without a trunk. So, if you clamp the equipment directly into the cartridge, without a flexible shaft, you can perform only some rough work !!! Because the tool is too bulky !!!. I also have a light one, which does not vibrate so much, and which is convenient to work without a flexible shaft, but the power in it is such that I gave it to my wife and daughter to polish the nails! )))).
.... Do you offer a screwdriver to do this !!! Which is many times heavier, and even with a "pistol grip" .... Do not tell people! First try it yourself before you say anything ...
It is impossible to make a collet clamp "on the knee", because, even manufactured at the factory, they (collet clamps) often have a very large runout.

Sorry, but if your hands are not sharpened very correctly, this does not mean that this is impossible in principle .... I did home-made collet clamps back in the USSR, because they could not be bought then. And he did just that - drilled with a static drill, rotating the workpiece with the Alesya drill, and then cut it with a hacksaw blade.
And then clamped a 1mm drill into them and worked. And the drill did not break ... Do you think there was a strong beating there? ))))
Author
You are wrong. She completely copes with the functions I desire, even without complaints. So to your joy or sorrow, this is not a useless trinket. Although you can call her what you like. In response, I could like you eloquently and rudely, to negatively respond to your work. But, upbringing does not allow me to do this, and this resource was not created for that.
Sincerely.
This is not a bauble - it is an absolutely useless bauble. It will not perform the functions desired by the Author, because it's a complete bullshit. It is impossible to make a collet clamp "on the knee", because, even manufactured at the factory, they (collet clamps) often have a very large runout. I bought Chinese - garbage.
Yes, and think for yourself, fasten the bearings, which are mounted on a shaft made of a bronze tube, filed on both sides, filed in a screwdriver's chuck ... This is just class !!! Then we put these bearings into a plastic tube ... and we get an “ideal” holder for a self-made collet clamp. Cool!!! The most interesting thing further ... it turns out that in order for all this "horseradish construction" to spin, you need to have a screwdriver in which you simply insert the blue-white boron (in the last photo) and do what you need, the author was just "zapadlo", because he is not looking for easy ways.
As a result, I will tell you, dear residents of our site, this "SimBurDa" (simulation of violent activity) really amused me.

The essence of the idea is described in the article. Not many people are lucky as you have finished materials and tools, and have knowledge in this area. Just for such an audience the information in the article is designed. About the use of cables or other materials, I repeat, I will only be glad if someone does better and better. The main thing is that my work would benefit at least one person.

The purpose of the article is designed to give readers an idea.

Excuse me, what's the idea? I did not see anything that I would not know before? Valery here wrote about the speedometer cable, and that was it. And then I was lucky to get dentistry ready from drills.There are two types of such houses at home, already industrial production. One powerful with speed control, the other in the set.

Bearings are not required to be used from coils. The article says that there are such on sale. But for effect and in order not to disappear to the broken coils and cable in vain, I used them. Everyone can use for themselves materials with better quality. And if you make the tool better and better than described in the article, I will only be glad. The purpose of the article is designed to give readers an idea.
In general, the idea is interesting ... I have three spare flexible shafts from the engraver. With collets and other things. (Took a lot on Aliexpress) I have an engraver, but I also want to try to make the drive more powerful and slower (for a certain type of work. For example, cutting glass with a diamond wheel). I think to use a screwdriver. I have a 220 V with a 750 W motor. It is powerful (the speed will not drop under load) and it is well executed speed control, plus three speeds.
The work is done well. The author is well done ... But the result, as Delasius rightly remarked, is not entirely satisfied .. Somehow, "by the way" everything is done ...
Bearings ... Why are they necessarily “off reels” ?. You can just pick it to fit. Even if you need exactly the same ones, it is better to buy them not at the fishing store. Firstly, you can take a closed type, and secondly, bearings of much lower quality are used for coils, roller skates, etc., than for mechanical engineering and industry ...
A flexible shaft (namely a flexible shaft, not a cable) can be taken from the speedometer of old cars.
Author
Thanks for the positive comment)))
Bauble. Bicycle brake cable not designed for torsional load?!. Enclosed bearings are easier to apply than clean each time? Collets cost a penny than to do. Moreover, they need different sizes. And the motor can be selected separately than to "ruin" a good tool. This is so offhand.
