In many electroplane use replaceable thin blades with double-sided sharpening. While these knives are considered disposable they can still be sharpened. For sharpening these knives offer to make a simple device.

That's such knives in question. Any knives need to be sharpened electroplane pairs to retain balance. Although such thin knives as possible is irrelevant, but optimally sharpening knives do two at a time.

Here we take 50x40 mm cube and a little longer than the knife in my case - 90 mm. Such knives have a sharpening angle of 45 degrees, however is the triangular cutout in the bar. Such that the plane of the bar faces the recess is 45 degrees.

comfortable doing it on the circular saw exposed to the desired angle. After the cutout triangle drop the saw to make another cut under the knife. These blades are usually 5.5 mm in height, so the saw must make a groove about 4 mm. Rip saws are also push up to the stop disc saw to a new groove depth was approximately 1 mm. It should look something like this.

Further, screws can be secured with a press washer knives on the device and via the abrasive bar sharpen the knives on one side.

After sharpening, you can turn the blades and sharpen the other side. Next, set in the plane and use.

In practice, such a device handy when working in the country. It was necessary to ostrogannoj about cubic meter of boards on both sides. it was about 35 km to the nearest shop, and to fit - my reach. Sharpening one side missing 0.5 cube crude pine boards, and the time it took for sharpening knives and replacement took approximately 20 minutes.

Even for the sake of completeness offer watch a video about how this device was manufactured.
