I turn the key in the old Perov drill

It was a pity to throw away the brass key from a broken lock. Durable very fact, everything is thought to attach to his farm. And now I decided to try a novel idea - to carve out his drill on wood, Something like spade drill.

To work only used grinders with a circle of metal.

Step 1

(The pictures I simply show the sequence, but this time the drill itself is ready. Therefore, it is not guided).

First grind the end of the key, giving it a flattened pointed shape. So it has become a bit like a pen. Special accuracy is not yet needed, then all still have to tip again customized.

step 2

Next, put the key vertical plane trimmed on both sides. It all depends on the undercut key, I had to move somewhere 4-5 mm, while reached the flat areas of plates on both sides (compare with the key to the work on photo 1).

step 3

Then did the same thing and at the sides. This operation will allow to adjust the size of the future drill a desired hole diameter. The key that I used meets feathers drill 17-18 mm, so

From it you can do a drill and other smaller diametersBy measuring the dimensions of the wings and fit them to the desired size.

step 4

Crucial moment - sharpening the upper bounds at a slight angle wrenchSo that it is well cut tree. I looked at the feather factory and made the sharpening in the same direction. If even sharpen the edge in the other direction, it will be possible to work in such a drill in reverse mode.

step 5

It remains to cut the grinder head wrench, remove burrs and to start testing the product. After all these cases take the drill chuck and drill souped'm going to find a piece of wood.

step 6

Well, go ahead! Frankly I do not remember how bored I have a new pen of the same size, but I think the bit of the key to make the hole better than new, and quite quickly. Region to get a smooth, fiber does not break, and if it is always possible to slightly erode.

The result pleased, now I know what to do with these keys, as long as the metal in them was good. Try for yourself!
