Hello. Sometimes you need a sharpener with a very high degree of flatness. It is not
an easy task to find such a machine. But you can do it yourself.
It's very simple. This machine has a disc made of wood, which is
glued beneath of the disc of smooth glass. A cordless drill will revolve the disk.
Now I smear homemade grinding paste on the disc. After completion, you can start sharpening
hair clipper knives. Well, everything is ready to go.
I have an old hair clipper that is already blunt. You will see that the machine is blunt.
First I will show that it is really blunt. As you can see, it just chews my hair and
does not cut. So now I try to sharpen the hair clipper's knives.
The hair clipper has two blades, upper and lower. It is necessary to sharpen the two.
The contact surface should be much smaller than the thickness of one hair, otherwise
the hair clipper will chew the hair and won't cut.
Upper knife sharpening is easy as I can hold this knife by its lever.
I'll sharpen this knive three to four minutes until the
plane of the knife acquires uniform shine. This will indicate that the plane of the knife
recovered. I could not hold the lower knife, so I made
a piece of wood and hammered two nails through the holes of the knife. We have
to work more carefully, as the knife tries to slip out of the device. Either way I was still
able to sharpen the lower knife. Now I have to clean the blades of the grinding paste.
Now I have to put the knives in place.
Now I need to check the hair clipper. Excellent. Now the hair clipper works like new.
That's all. Thank you for your interest in this video. Bye.
