Good day, dear the inhabitants of our site!
This article will be of interest to anyone who often encounters welding. And they, as a rule, require high accuracy and attention. Given that you have to work almost always alone, it is very problematic to keep two parts to be connected. Clamps and other types of fixatives can be used. Channel author Samodelki Vitmana will show you how to make it in a few minutes devicebetter suited for such tasks, a magnetic square.

Instruments.
- Bulgarian with stripping discs and conventional
- Drilling machine
- Drill or screwdriver
- Band-saw
- Hacksaw
- Clamps, vise
- vernier caliper
- Ruler square.

Materials
- Ring magnets
- Steel bar 24 mm in diameter
- Steel sheet 2 mm thick
- Steel tube with a diameter of 15 mm
- Bolts with nuts and washers M6.

Here are the main details with which the author will begin to assemble the device. Two magnets from a microwave. And the steel plate is 2 mm.



A small drawing of the future corner.

Manufacturing process.
Marks a sheet using a square.



Cutting off the triangles with a grinder, strips the edges, checks the geometry.



The author will make two squares at once, so these four blanks turned out.

A hacksaw cuts six bushings from a steel tube. They will separate the plates at the corners.






Then, using a caliper, marks the workpiece.




At the intersection of the lines you need to drill holes, there will be mounting bolts and bushings. Before drilling core.

Then, it pulls together two workpieces with clamps (this is necessary for the exact coincidence of the holes), and drills two at once.


With the help of a band saw, two cylinders are cut from a steel round log. This will be the sleeve for the magnet.


Also core, and drills a hole of 6 mm.


After stripping and painting, such a set of parts turned out.



One corner has already been assembled, shows how to assemble using the example of the second. There is nothing complicated.








Checks the geometry, everything is fine.

And connection tests from different angles.There are two main angles - 90 and 45.






Thanks to the author for a simple but very useful welder in the household I will adapt!

All useful tools!

And I do not have a welding table ...))))
Why do I need it? ))). And what size should it be so that the gates can be cooked on it?))))

But seriously, the point of magnetic squares is precisely in saving time. With tacks, I will cook without them ... But what for is this hemorrhoids? That's just the tsimus, that at once you cook everything that you can reach)))). Then he turned over (once) already welded tightly to the entire length of the seams, the structure, and boiled the rest ...

And you can fill in with alabaster - finally 5 minutes.

Sarcasm, I caught, and on reflection, why not? Here Valery plans to cook something in the radius of the corners; such a solution can suit him. I do not know what prevents first from grabbing to the sides of the corner. I have, on the welding table, there is not a large conductor at a right angle, of course there is nothing for the magnet to do, and when the workpieces allow the use of a magnetic corner, why not use it.
Graters in general are about nothing.

Epoxy it, epoxy. a bucket is desirable! =)))

Otmaz prokanal!))))
In general, when welding, splashes fly off from the arc ... Sparks are like that ...))) And they fly so 10 centimeters .. And the corners are cut ... In order to get there as close as possible to the electrode ...
And how can you cook only at such a distance from the square?))))

And the metal "warms up" on oh-oh-oh-oh what temperature ... Enough and seconds ...

Foam, polystyrene foam and so on are not at all compatible with welding, sorry ....

A controversial statement, do you plan to cook right in the corner or are you afraid of not prolonged contact with heated metal? But, I will try to otmazyvatsya - blurted out the first thing that came to mind.

WHY do bad in advance

Verily, the golden words are spoken in time.

(you can even foam)

..And then do not use when welding ....))))))
So ... Purely to show friends ...)))). And then to those who never cooked by welding ...))))

, what prevents to change a magnet every 2-3 years?


.... The lack of a “living” magnet at hand, for example! (Note that it does not stick when it is needed, after all))))

And in general ... WHY do you do it in advance if you can immediately assemble aluminum rivets and forget? !!! ... Here the author is obviously just “not catching up” ...
Yes, and the strength of the magnet fell during the "shorting" of the poles ...

Such a thing comes very often !!! I cooked a wicket - a sweet deal !!! I cut it exactly with a machine tool (home-made), “glued” it onto four such squares, boiled it - everything, including preparations and stripping, took about half an hour - and the frame is ready!
... I also did it to myself - look at the profile, if interested ...... But then they somehow "sharply fell in price" - now a simple square can be bought for 5-6 rubles (2.5 - 3 $ ) ... So I just bought a few more pieces ...
..But we are not talking about the usefulness of the product, but about the curvature and lack of knowledge of the performer!

Comment only at the request of copy-paste.
I agree with Valery, it’s not the smartest decision to leave the magnet unprotected (you can at least foam it), but what about the “started demagnetization process”, if the product is in demand, what prevents you from changing the magnet every 2-3 years? On my own behalf I’ll say that one day such a thing would be useful.made a 4-roller block and when welding the axis deviated slightly, such a corner would eliminate the need to redo

And, again ... How is he going to clean it? In a couple of hours he will look like a hedgehog because of the “Bulgarian” sawdust and welding scale that adhere to it !!! If the ends are closed - he pulled everything together with his fingers in a glove into one pile and "pinched off" ...
And how to extract this “ganjubas” from the inside here?))))
... Although ... The poles are already shorted! The "process of dying" of the magnet is started - you can not bother removing the magnetic crap from the inside! )))). Throw away anyway soon ...

It is very "competent" to connect the poles of a magnet with thick magnetic material !!!! ...
Yes, and shove it inside !!! ...
