I went on an interesting topic on the Internet - if a stick or sheet to a certain way to exercise or promoted, the tree begins to bend practically as a rag. I decided to try
He took a sheet of plywood and made such a milling. 10 cm long holes, through, each row is shifted relative to another 5 cm.
This work is not for people a for a 3D millinger, very hard. But it turned out, it's very easy
yet
Whatever the works disappear decided to make something useful from this workpiece.
Musted the grooves under the porch tail
Here, ready
Cut the strokes, they also got a swallow tail, only spike
and inserted into the grooves
It turned out a dollar :)
Despite the harvester look, it turned out a very rigid design. And I think I was wrong with the form, it was necessary to make Bitcoin, I would sell more than a thousand times more.
