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 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.
The coil is the most convenient form of packaging thin sheet materials and for the transportation and storage in warehouses. Foil, a synthetic film or paper in a tightly collapsed become a monolith, convenient in handling and are not particularly suffering from the hard grips of different mechanisms.
Once instructed the boys to handle on turning the glasses of the part having a stepped hole. The hole is cut, usually in two stages: first inserted into the rear Babin smaller drill bit — drilled the hole, then a tool with a wedge knocked out of the cone and there you insert a different Read more…
Built-in furniture for country attic. As a rule, country attic (the so-called well-maintained loft happy owners shestietazhnyj plots) — the room is not too large, so that linen cupboard and a couple of beds can take most of it. Meanwhile in the attic for placement and cabinets, and beds it is possible to use the volume located between the sloped roof slopes and vertical walls.
The idea is to make the jigsaw came to me many years ago, but brought it to life much later — when I got someone thrown the faulty sewing machine production Podolsk factory. From the “inside” machines only took the main shaft and the node of the “needle bar”, and other parts dismantled. Cut and the front part of the platform, leaving only a foot under the bar of a G-shaped case. On the sandpaper I ground off all the tides on the lower surface. The bearing at the corners of the drilled hole and through them, inverted the machine was attached to the top of the pedestal bottom. By the way, the Cabinet is also used from the old foot-operated sewing machine. However, to find such a Cabinet should be harder than the machine itself. But it may or may not be made of chipboard with 20 mm thick Top cover closed steel sheet thickness of 1.5 mm (and dural).
Who in the circus like children? Of course, fun and funny clown. And a shaggy red wig, and bright baggy clothes with huge shoes, and tricks — all causes kids (and adults) happy laughter. Such a funny figure of the Croatian magazine “ABC technology” and offers parents do for their children, perhaps with their involvement because if you do not cut, then paint the bright colors of the clothing of a clown any boy.
A souvenir depicting fairy-tale “the Firebird” with the use of LEDs, can make even novice hams. The details of the electric circuit, except the LEDs are placed inside a plastic soap dish suitable sizes, are the basis. Two red (or orange) led, is inserted in place of eyes, connect to the unsymmetrical multivibrator, and seven flashing LEDs in the tail feathers twinkle themselves. Details of the scheme: VT1, VT2, R1, R2, C1 is located on the PCB about the size of 40×20 mm, which is fastened inside the base by two screws M4. The power switch (microtubles) is displayed on the top cover.
Creating some kind of mechanism or tool, the person usually by its name defines its main functional purpose. So, saw, saws, drill — sowing, the hole punch punch holes, and, say, a wrench used for screwing or unscrewing the nuts.
Rare design can be build without the use of welding, particularly electric arc. This is why a good welder is a dream for many designers and enthusiasts. The “heart” of it — the welding transformer, which will be discussed. Winding step-down transformer (Fig. 1), connected to the original circuit (Fig. 2) provide arc stability. For welding use electrode Ø 3 mm, designed for AC current. (In the forced mode of the transformer it is possible to use electrodes with Ø 4 mm.)
