Grinder, the simplest scheme


Hello everyone. Not so long ago I made myself grinder, on it I rule, polish the surface and bring down the slopes. Sometimes you need to rearrange from large to small paper, frankly laziness, and so I decided to make myself another, but more simple and without troubles.

With two grinders it will be easier - no need to run to put one paper, then another. I sat thinking about what he should look like, looked at the metal reserves and figured out how everything would look.

And so we need engine, two pieces of profile 25x25mm, two tubes for 20mm, two bearings 20mm outer and 8mm inner, any tensile spring and a standard set of tools.

So here we go: I have a 220 V 200 W engine, with speed control

Now about the tube: a tube with an inner diameter of 10mm, thickness 3mm. I’ve got a pipe from an old non-working pump Aquarius, lying around idle and useful, and any one will do - the main thing is that it sits on the shaft

Now I step back from the edge of 3cm and drill a hole of 5mm. This is necessary for mounting the roller on the shaft. You can also make a groove on the shaft and the cotter pin, but I did not bother

Now stepping back from the edge, I drill a hole on the 5mm shaft, then I put the tube onto the shaft with a cotter pin nut

I need to make a stop so that the paper does not run off the rollers. I rummaged through nothing suitable. I found 4 scary washers, I have to cheat with them. And so I drill a hole in the washer under the tube and put the washer on the tube

Carefully weld the washer to the tube on both sides. I let it cool down a bit and grind it with a cutting disc, removing sharp edges

Well now it's time to assemble the frame. The shape and size of the frame does not play a special role. I took two pieces of profile 25x50mm

One piece will go to the consumable, from it I cut three pieces of 10cm

Now I weld pieces in the form of a square and weld to the profile, well, now the frame is ready

From a piece of 10cm tube I make a roller, I press bearings into it 20mm outer diameter, inner 6mm. From the edges to the tube I weld the washers, as on the first roller. I drill by 5cm indentation, drill a hole in the frame, put the roller on the bolt, insert it into the drilled hole and weld on the other side

Based on the design of his engine, I decided to fasten it to a bolt. I drilled, stepping back from the roller 15cm, I fasten the engine to a bolt. In the photo, the engine is in a distant position from the roller.


Well, our grinder is ready, you can use it.In the photo, the engine is in the near position from the roller after putting on the tape, we tilt the engine and fix it with the necessary belt tension

It’s just that I had a semi-finished knife lying next to it, it is necessary to polish it with goy paste. For such purposes, I have a thin kashma for paleting, I put on a grinder on the grinder and turn it on at the smallest speed - everything works and slowly added speed, somewhere I can’t optimally calculate the speed, but I selected the right speed


Well, friends, it's time to say goodbye, with the last word I want to say Thank you to the site for the fact that people like me are simple, just starting, but dedicated people do something do it yourself and earn. One thing offends me is that people write that you make a knife from bad steel, oh such steel is only suitable for spoons, oh I know all brands, and your knife is .... oh - I do not respect such people, but everyone has the right to your opinion. I understand that I do not have good steel, but why do I need it? to peel potatoes? Yes, I have jambs, but who did not study.

Would paint though! Everything is rusty like from a swamp!

Yes, parnography! Paint and discard.

Now they will tell you that you are wrong, that this is done with your own hands, and it does not matter where they grow from.

I completely agree with this
These craftsmen worked and work in production.
What he actually boasts of. Sloppiness.
It’s disgusting to watch. He does not respect himself or herself.
From nature, it’s not in sight.
And the echoes of such "masters."
Here Russians are considered fools because of such figures.

The problem of so many of our masters is the lack, or very low, understanding of the culture of production. Yes, somewhere this historical influence, we have never been in the forefront of the culture of production. And she is very weakly vaccinated in educational institutions, unfortunately. But with age, willy-nilly, you start to look at it all with different eyes and are horrified.
Take at least this craft. Himself not ashamed to put it on display?
Okay, welding seams you don’t have a fountain - this is understandable, not a great welder, by the way, too. But why not clean them from slag and scale?
Or - what was it worth to first clean the pieces of iron from rust with a brush? You will enjoy working!
And "grinding with a cutting disc"? Is it from the lack of money for a normal petal disk or from laziness?
The same thing with the sleeve on the dvigla shaft - are you most pleased to use this rusty crap? I understand that you manage with trash, by the way, I also often, but I would be ashamed in front of myself to leave it in this form. Moreover, you could, having switched on the dviglo with the plugged-in sleeve, walk along its surface with a grinder and make it shining!
In general, you can talk a lot, from the workbench to the painting of the finished product, but I think the message is clear. For handshaking is a plus, but the quality of your work is not just frustrating - it offends. Look at YouTube on how Diresta, Laura Kampf and other ironworkers work, pay attention to their attention to detail, to the culture of production.

I made it myself, practically from the trash, the necessary and practical thing, the easier it is to manufacture the better, in all respects the offset, but why not so carefully, why the fucked up how crooked?
Guest alex
But just bushing from the bike was not fate used?
Guest Alexander
I subscribe to your every word! We hope that the author will take into account our comments! Well done!
I completely agree with this !!! I also often make homemade stuff from trash. But, after assembly and launch, I always have a moment that I call "comb")))). This is disassembly, cleaning, painting, assembly with new hardware and plugs.
The main loss of working time is just devouring the eternal reconfiguration of the universal manual machine.

I often repeat that "Grater should be a grater, and a meat grinder, a meat grinder!" And if it is combined, then it either rubs poorly or grinds poorly ... And more often - it rubs and grinds well, but, as long as you redo it, it's easier to rub it manually! )))))

Naturally a big rusty plus.
The approach is really industrial.
From what is at hand here and now I’ll assemble a device that will save my working time. That grinding and painting the frame is not optimal, it will not take much time, but it will protect it from rust. It is reasonable to fill the tubular frame with sand and drown the ends to make the frame tougher and the work quieter. Home-made rollers required careful manual work, but do not allow for the possibility of clearing the play when the bearings wear. In the role of a roller, it is convenient to use bushings from bicycle wheels. Ready-made are very cheap, used in general for nothing and made quite accurately. The resource is generally crazy, and if the roller is not planted cantilever and inside the tape ring there is an emphasis for the second end of the roller axis, then the life of both the tape and the grinder itself will increase very much. Described by me for many years worked in an aircraft model club in the 70s. Applause for the tension of the tape by tilting the motor is a separate plus, and for the refusal to adjust the angle of inclination of the roller - applause. And for the implementation of the principle, one working operation - one tuned machine - bravo! The main loss of working time is just devouring the eternal reconfiguration of the universal manual machine. Thank you, reminded me that smart and handy people are still alive.

Korean engine everything in Korean is clear one 220 volt 200 watts. The engine itself has a twist and five modes with increasing speed on it
Well done Alexey !!! I respect people like you. Your hands are growing from the right place. And about the insolent comments, do not pay attention to them. There are people who want to "cheat" everyone and everything. They also wrote a lot of bad things to me, so do they even know how? Or just write nasty things?
