At the regional exhibitions NTTM they attract the attention of visitors of all ages. And no wonder! The search range of the young designers wide: training glider and walking robot, a flying car and microtracker. With every new car the guys are in the way of true researchers: outlining the purpose, carefully studying the existing experience, then, given their own capabilities, define the technical requirements to future design and finally design and build it.

For a man, far from technical creativity, the expression “reinvent the wheel” has a negative connotation: a waste of time, repetition of already traversed.

Today there are more than 20 thousand patents for a variety of venoconstriction! And the search continues. And it involves not only professional designers, but also a large army of Amateur enthusiasts and fans of pedal techniques, including readers of our magazine. The direction of this search are diverse, but among them we can highlight some General trends.
The kit tank consists of two round metal mesh laid on top of apples: the first with a mesh size of 1 mm, the second is 0.5 mm (So that the grid didn’t crash on the perimeter they opany); hardwood (oak, beech) CD-punch with holes for the passage of juice, another disk of smaller diameter (not blocked hole punch) and spacer-boss from a wooden bar, used when there is not enough stroke of the Jack.
After reading in the “M-K” on the continuation of the contest “Small mechanization”, decided to take part in it. I propose a simple and compact micromelic. About the size can be judge by the pictures: the whole structure fit on my one hand. It is universal: designed for the production of corn flour of both large and fine grinding, crushing various zernatto and preparation of feed for livestock and poultry in their personal farms.
