Was such a nice family tradition in many old houses, as soon as the child begins to walk, he measured his growth on the painted with oil paint the door jamb appeared first stab notch marked when it is applied. The number of such notches with the outline was added with each birthday is a kind of chronicle of extension of the child.
When books on a shelf a bit—they are unstable and fall. And folded stack of inconvenient to use: we need not so easy to remove from underneath lying on top. It is therefore desirable to have a backup, which would provide the books in a vertical position always. In commercially available plastic and metal corners for these purposes, but they are uncomfortable, not very stable, sometimes we do need strengthening.
The article with the same name, telling about interesting decorative works from wrought iron, made famous Yugoslav craftsman Dmitry Petrovich (“M-K”, 1977, M 8), attracted the attention of readers. In the letters received, there were suggestions to continue this topic. For those who want to decorate your home interior crafts crochet with metal wire and steel strip, put some more designs from the book of D. p. “with Their hands”.
Thousands of people are collecting seeds, preparing soil, growing seedlings and planting them in place of felled forest. One-two seedlings no problem, dug a hole, covered the tree with earth, watered and that’s it. But if you want to prepare the plot for dozens, or even thousands of seedlings, without modern technology to solve this problem is impossible. Machines able to plant plants in the ground with accuracy, worthy of the hands of the gardener, and performance, it meets our industrial age created. That’s only work they are able to not anywhere. Give them an equal place and space. Yes, and deliver them to the place of cultivation, for example, in remote areas difficult.
They look close to the “classic” scheme: have a body and a fixed jaw, a screw that moves the movable jaw, lugs for attaching to the workplace. But for all its similarity to conventional new grip thanks to the clever solution of their design has acquired much greater opportunities, become universal. The main feature of the original clamping device, developed by Turner M. Babichev, Vitebsk machine-tool plant named after Comintern is movable sponge: it is made in the form of rotary drum. In other details the innovator has made the changes.
For modern engineering and many other sectors of the economy it’s not uncommon for such large structures, in which the Assembly or disassembly of powerful bolting already exempt from the ordinary hand tools or power one working. That’s why the innovators of Novo-Gorkovsky oil refinery created a powerful Electromechanical wrench. It is a two-stage planetary gear associated with seriesname DC motor with a power of 0.9—1.0 kW. The torque transmitted to them at the nut is 825 KGM.
To put digital markers on trees — work is necessary, but time consuming. We managed to make a simple device that allows you to quickly and accurately “print” a mark on the barrel. Organic glass glued octagonal drum and planted it on the axle fixed to the holder with handle. Then, on the surface of the faces struck the contours of the digits in a mirror image, and drilled holes Ø 1 mm, uniformly fills the outline of each number. Holes on top of the glued cut felt figures. On the side of the drum is made a threaded hole for pouring the paint, and shut the tube.
In the “Modeller-designer” has repeatedly published materials on woodworking machines-“circular saw” circular saw and planer, so necessary for the house masters. On this publication have done for a similar machine and I. But when I did, I realized that not everything in it is fine with me. In particular, the mechanism of lifting-lowering of the table. And the device is called the mechanism was only possible with the big stretch. The table was mounted on four studs-the uprights and vertical movement required to turn is to roll as many as eight nuts. And to set the plane of the table parallel to the axis of the plane (and saws) had “by eye”. In the end decided to make another table with more “advanced” mechanism (table) of lifting-lowering.
Improvised creativity are addicted to for a very long time. And in many respects it was promoted by my favorite magazine “modelist-Konstruktor”. Released since 1972. The recommendations and tips magazine has done a lot useful on the farm structures. The biggest of them —the tractor Arkhipova (“M-K” № 1, 1984), Gromov and all-terrain vehicle (“M-K” No. 1 for 1985).
Applied the last stroke of paint on the Board-float; the number sewn to the sail, varnished mast and you start thinking about the first release in the “open sea”. But, before you do that, think about your outfit. After all, the very peculiar windsurfer sailboat and, of course, requires special equipment.
