Making simple sharpener for a chain saw chain

Hello Kulibins and diy. Today we will do a device for grinding teeth is not a chain saw, electric or gasoline, there is no difference.

This post was born to me looking at the neighbor's cottage. I traveled recently to visit his villa, and at the same time and brought the food to our security dogs. A guard of our cooperative is my neighbor, who has lived in the country all year round. In general, we caught languages ​​with a neighbor about this and that, and in the course of the conversation the neighbor honed his electric chain saw.

I took a round file and sat chukha each tooth back and forth. We spoke for 20-30 minutes, during which time he sharpened only one tooth. I am a compassionate person, I felt sorry for him, I brought him a sharpener and hammer that are made from bearing. As a result, he sharpened the rest of the teeth for about 15-20 minutes.

I'll start with the theory. The photo below shows a cutting tooth blade that is sharpened correctly.

For comparison, in the photo below, so looks like a saw tooth that blunt.

Of course, some buy a special attachment for drills, designed for sharpening them, but we like that happened to sharpen by hand using a round file.

The diameter of a file is selected according to the characteristics of the tooth and the step chain. Below is a table to help choose the file.

The following figure shows the position of a file during sharpening. Depending on the model and the saw chain sharpening angle can be from 10 to 30 degrees. These data should be indicated on the chain itself well, or in the data sheet.

The theory will end up, proceed to the practice. We need a bearing, a small section of a tree branch and file itself.

Take the branch, the thickness of which must be greater than the inner diameter of the bearing. Branch debarked and inserted into the inner ring of the bearing.

It is desirable that the branch was in thickening and bearing has been fitted onto it tightly as possible.

Then hacksaw saw off all unnecessary.

As a result you get is such a thing. Bearing with wooden insert in the inner ring.

Then mark the center of the wooden insert. It is very important to make the most accurate alignment.

Then drill a small hole in the target center. It can be through. The diameter of the drill is likely to 2-3 mm. In the photo drilled conventional nail as thin drill just did not have)))

And yes, during the drilling bearing scrolls. I just put a match under the bead to fix it for drilling.

The drill hole put in our file for sharpening, preferably tightly, you can kill a couple of times with a hammer.

The reverse side of a file clamped in the chuck screwdriver. Shurika the neighbor is not so inserted in the drill.

Well, at this stage, many have probably realized the essence of the work of this device. And who does not understand show.

Immediately I apologize to those who expected to see here a complex engineering structure. As you can see, everything is possible simply and quickly.

Well now I am waiting for your opinions in the comments. Tips and suggestions for the modernization of this adjust.

In this allow to finish. Since you were Mikhailovich, all Peace and Good!
