Chain saw from grinder, tire and chain


Friends, hello again. Made another useful homemade yourself in garage and to the country. I have a grinder, I bought a tire, a chain and an asterisk for a chain electric saw in a hardware store and assembled an excellent removable nozzle for a grinder. To my surprise, the saw turned out to be quite productive and powerful, in any case, it’s very useful for trifles in the household, and it cost $ 22 in cost.

Let's see the process of making homemade video:



Materials and tools:
- grinder;
- tire;
- chain;
- driven chain sprocket;
- a piece of metal;
- drill;
- M6 bolts;
- paint;
- drill;
- oiler;

So, for starters, we remove from the turbine everything that bothers us and cut out a plate of metal of the size we need, and I picked up the cage from the bearing of the desired diameter for the seat for the protective casing of the turbine:


I turned a little of the cage wall from the bearing so that the attachment bolts to the impeller could be screwed on without problems and nothing would interfere.


Next, we measure and drill a hole in the metal plate and weld a cage from the bearing to it and drill all the other holes we need for fastening to the impeller and mounting the tire itself.




When we have prepared everything, we begin to assemble our product into a single whole

To this fixture I made a small protection in the form of a casing on the chain and attached a grease fitting to lubricate the chain.



Friends, I can tell you with confidence that it is worth doing such home-made work yourself, since it can be very useful to you on the farm, and as always, making it yourself is much cheaper than buying in a store. Thank you all for your attention and interest in my work.

IMHO, all such alterations of the instrument here - this is not from a big mind. Any chainsaw, benzo or electric, has one extremely important function - the chain brake. But the saddest thing about this is all that the author also calls for repetition:

It's like jumping from the 9th floor, surviving, and then advising others to try.

No need to collective farm. The Chinese sell ready-made kits cheaper. Having added a little to this amount, I bought an electric saw in Leroy.

Author moron ragged. After such home-made work from an illiterate person, people lose their limbs. Petushara author go teach physics

I alone noticed a tendency: the message to teach physics is always voiced by stupid fools, who themselves in physics - not even a foot ...))))? (electrical engineering, mathematics, mechanic ... I need to emphasize the necessary ... But ... More often, all the same it is physics))))

As for the home-made, he also once did it. True, from the 230th grinder. There, the speed coincides with the chainsaws in general completely ... (In the sense, well, they do not exceed) ... But, without lubrication. the chains "went away" instantly ... I tried to smear it with a grease fitting manually (as we once did everything on Druzhby and Ural, with their eternally faulty automatic lubrication systems), but it didn’t work at such speeds - anyway " burned "tire and chains ...
I doubt that the gravity of the oil will give something ...
And here the "expert" is essentially (not in form) right! Someone can repeat homemade ...

You know what !!!))) And here I am, a supporter of the fact that "let the morons die out!". If you want to do something like that, then it also means that you UNDERSTAND THE TOPIC, and you know very well HOW IT WORKS !!! And if you don’t know how the angular velocity differs from the linear one, then either DO NOT TAKE it or die! ))) ...
In short - if you UNDERSTAND the PROCESS, then it is not dangerous for you! And, if, stupidly repeating - then the responsibility for your injuries lies with YOU !!! And this is your choice !!!
Here it would be necessary to put the "expert"
I agree, rudeness warps!
Who says that it is necessary to cut firewood with THIS

That would be a "connoisseur" in place. Who says that it is necessary to cut firewood with THIS.

Well, firstly, the rotations on this grinder are regulated, and secondly, at maximum speeds, the speed is not so high, I have a purchased power saw, it feels like the chain speed is higher on it.
are there not too many revolutions for the chain? teeth from the legs do not have to pick out?
