When my family moved to is not a new manor house with land, I faced the problem of its thorough repair and erection of outbuildings. It was clear that with only hand tools this kind of work will not do. And therefore decided before you start construction, along with concrete mixer, to make at least a simple woodworking sawing-planing machine, called artisans “circular saw”.
The development of specialized agricultural systems is unthinkable without the complete mechanization of manual labor. Many vegetable) crops do not require manual labor for their cultivation and harvest. But the stumbling block to this remains the mechanization of harvesting cabbage. Not developed cabbage harvester our industry. So we have in ancient times to strike each head, to put in baskets or bags, and then load the trucks. And all by hand.
The readers of “M-K” has long been known to experienced lab simulation and design club of young technicians of the Siberian branch of the USSR Academy of Sciences. A development of this laboratory is reflected in the pages of our magazine. We offer you the latest, very, we think, interesting design that was exhibited in the summer exhibition at the VI all-Russian meeting of young rationalizers and engineers. This triple car “March-77”. On his device, says the head of the laboratory of M. L. Larkin.
Amphibious Schwimmwagen (Volkswagen Typ 166) — German floating four-wheel drive all terrain vehicle for military use, developed on the basis of “national” Volkswagen Beetle and army all-terrain vehicle VW-82 “Kubelwagen”. Produced from autumn 1942 to the summer of 1944 to the Wehrmacht and the Waffen SS instead of heavy motorcycles with sidecar, appeared on the Eastern front because of low passability on the roads, and especially in slush.
For drying clothes usually are stretched one or two ropes, but wide things on them is placed a bit, you have to lengthen them. However, if the Laundry on the clothesline to hang not along and across, things would fit much more.
Wood handle plumbing tools will eventually fail and require replacement. Buying or making a new one, not in a hurry to wear it. First, on the shank of the chisel rasp, make several oblique notches — they firmly hold the handle of a jump-out, and that lasts a little longer, put it on the front Read more…
The need for large apertures of various diameters occurs very often. Some cut them with a jigsaw, others use a drill and then sanded the edges with a file, others are turning to so-called centraliza — fit to a normal drilling machine.
To saw thin-walled metal pipe clutched in a vise — employment is not easy. Not only because the accompanying screeching grates on the ear. The work itself is difficult: in one direction the saw is more or less easy, but the other can’t get. Especially if the material is soft, e.g. aluminium. Put in place Read more…
What happens if you cut a cylinder and two parallel planes at an angle to its axis and to replace the resulting “pancakes” wheels of a conventional car? It turns out that in the end we will get the vehicle of the increased passability. On normal roads this car moves exactly the same as a car with standard wheels, because at any point, the distance from the road to the axis remains constant, equal to the radius of the cylinder. Of course, with the difference that leaving a trail is not straight, but curved in the form of a sine wave.
Maximum simplicity, minimum weight and dimensions at optimum amenities available materials, components and assemblies, simplified (not at the expense of quality) manufacturing technology – all this formed the basis for the design of the car, which was later called “Yauza”.
