DIY do-it-yourself pencil

Instruments / Metal

Hello to you, dear the inhabitants of our site!
In this article, which is very useful for us working in our workshop, both with metal and with other materials, we will again focus on marking devices. Indeed, the correct and accurate layout of the workpiece is the key to success in the finished product.
The author of the Be Creative channel has something to say about this. He made a marking pencil from a brass rod and an old broken drill.

Materials
- Brass bar, diameter 10-18 mm, at the discretion of the user.
- Old broken drill 2-6 mm.
- Epoxy two-component resin, or super-glue.

Instrumentsused by the author.
- Band-saw.
- Lathe, cutters to it.
- File.
- A set of sandpaper of various grain sizes.
- Vise.
- A grinder with flap grinding discs.

Manufacturing process.
So, the author proceeds with the processing of the brass bar.


Grips him in the grip of a band saw.


It starts the machine, and cuts off the workpiece of the required length - in size like a fountain pen.



Sets the workpiece in the lathe chuck, clamps it.


Grinds the end of a brass bar.


Turns over the workpiece, also processes its edge.




Then he drills a hole in diameter, slightly larger than that of the drill being installed. Periodically pulling out the drill from the workpiece to exit the chips. Brass metal is relatively soft and viscous.



He rotates the headstock at an angle of 30 degrees, processes the second edge of the workpiece, turning it into a kind of sharpened end of the pencil.





Smoothes out irregularities in the cutter with a file.


The next step is a notch on the working side of the bar. In order that the "pencil" would not slip in the hands.



Grinds the "front" side of the workpiece with sandpaper.




Turns over the workpiece and processes its second side.



Cuts a notch.



A cutter makes an old and broken drill, sharpening it on a sharpener. Moreover, clamping it in a screwdriver, for proper alignment.




It mixes the components of epoxy resin, dips the tip of the drill into it, sets it in the hole of the brass “pencil”.






After the resin hardens, it cleans. It turns out here is such a tip.


Here is a notch after rough grinding.


The tool is ready, trying to mark on fiberglass.





The results are quite remarkable. Of course, this tool can also be processed on polishing wheels using GOI paste. But the author of this quality is enough.
Thanks to the author for a simple but good idea for the tool needed in the work!
Good luck to all!

We open GOST 8030-80
This is if the Soviet "gypsies" were lying around, and for modern (Chinese) manufacturers the keyword "wire"! smile

And why else are scribery needed, if not for marking "for hardware" ??
Are you a corrugated cardboard? smile By the way, a scriber can also be obtained from a "quick-install" screw.

Regarding suitability for marking sewing needles.

We open GOST 8030-80 "Needles for sewing manually. Specifications (with Changes N 1, 2, 3, 4, 5)" and we see the following:
2.3. Needles of all types should be made of steel needle wire of class A according to GOST 5468-88.
2.4. The hardness of the needles should be 56 ... 62.5 HRCe.

And what about a professional tool? Watching Catalog HOFFMANN GROUP 2015
And what do we see? Marking needles suitable for high strength steels have a hardness of 59 HRC.

But the needles are normalized in HRCe. We take GOST 8.064-79 and in its application from the translation table we see that 56 ... 62.5 HRCE correspond to 54.9 ... 61.6 HRC. That is, needles made in accordance with GOST 8030-80 can have a hardness even higher than that of professional marking needles.

Korolev,
And I regret my "diamond", I use it only on business, they are expensive for us! smile

He is enough for a long time ... I just have two of them. (I mean, two cups). One is "festive")))). In the sense that it is smooth.)))) And it hangs on a carnation, above the emery, waiting for accurate smooth work ... And on the emery it is installed "everyday"))). This is not a pity))). On it, I sharpen everything that is convenient - and grind something "into the needle", and drill bits on concrete ... Yes, a lot of things are convenient to grind with fine-grained emery. And the "diamond" here just right ...
Still, besides them, there is one “saw”. Here I regret that there is only one mm of diamond layer on it. I use it only for saw blades with victorious soldering ... (You can’t sharpen them with anything else ..)

Maybe. Yes, and talk heart-to-heart with him, oh, how could-))) But the character is so vague -))) In addition to open access, we still corresponded privately with him-))) in short, he got me so hard that I figured out , by indirect signs (photo), two more of his acca, on other sites. In short, they blocked it too-)))) But as for knowledge, yes, I agree

Despite the similarity of characters, there was really a “smart engineer”. I really admit, for example, a large amount of his knowledge and skills, for example, compared to me! ... He would not suggest welding a magnet to froth ...

There are many views because it is not clear why. In others, too, there are discussions and there are few views. I have been writing an article about a pistol for a long time and there were a lot of views. Well, I think they found what they need. Wrote the following, do not want to watch-)))

A good scriber is obtained from a narrow (thin) 4-sided file. And like kernels, it will go under drilling with thin drills.
And there are many views, because the discussion (and comments) is going on ...

Who would doubt that the most active er, er, inventors, will overwhelm this comment. It’s interesting, if the owner of the resource makes it necessary to self-make the pearls found in shit, how will you earn? Of course, you will make a cardboard doll or a crossbow on an elastic band, but will it pass the acceptance.

I do it with a big self-tapping screw, usually ... Since it is usually difficult to find the scriber in the rubble of the tool at the right time, I just take a larger screw (100-150), click the emery with a “diamond”, grind the end “to the needle” - one and a half minutes, and the scriber is ready ...
Already a lot of these are lying ..))) Sometimes you don’t have to do it - I looked, and found one ...)))

if red-hot - then it is possible to mark sheet steel

but no one could pay attention to the passage in the notch.

Is this probably about step failure? Well, yes, it’s important, especially when there is no knurling .... now you can’t scratch a straight line without a ritual of consecration.

The funny thing is that all the trolls liked the glue. Lathe too. but no one could pay attention to the passage in the notch. Everyone needs to ..... in the comments, while doing nothing themselves. What kind of speed do you have, trolls? Mine - 380 characters per minute, if bukhoy then 500.
PS this is me to the trolls. (does not apply to the border guard and other normal authors)

Leobrynn,
No, there was no one. It’s just that the author of this publication seems to have a creative crisis. And he can no longer write. Yes, and probably pay for the volume. This is how writers some of 5-10 pages describe a breeze and a butterfly flying over the lawn. And at the next moment, on just one line, this swallow eats this butterfly on the fly. So here, a bunch of pictures of the lathe, and at the end a drop of glue xaxa

The author is well done. him Respect
So I do not mind! I used to do it myself (I haven’t bought it yet), though I took a carbide drill (like they call it victorious), and I used a ready-made handle, I don’t know why, but with knurling.

Nice thing! Recently I bought in a tool store (not the cheapest one), a little more elegant and with a carbide on the tip and a protective cap, 75 rubles apiece. I bought 4 pieces at once, I will share it with my friends! smile
