For the photographic enlarger can be adapted and ready-made fur — like the old camera. If you find this does not succeed, do not worry — it is quite possible to do yourself.
On a frugal family night, guests brought a nice box of chocolates confectionery factory “Magician”. The mistress liked being in her truffles, and I was interested in the package: too unusual it seemed. To open it, without breaking the appearance, was not just because there was no usual bends, valves or traces of glue. Careful inspection helped to understand just what the box somehow folded from a single sheet.
The device, which we advise you to do, simple and affordable to manufacture a wide range of novice photographers, especially those who love tinkering. The appearance of a photographic enlarger is in the picture and the figure. Its main elements are: base, rod with reference fifth, sliding bracket, a lens with a focusing device and a housing of illuminator.
Strong, well-developed hands — the dream of all guys. The range of remedies that strengthen the hands, is huge. To hand firmly held a hockey stick, a tennis ranetka, easily controlled with paddle boats, use of tents; especially popular are the small, often improvised from a piece of dense rubber. However, this simple homemade sports has a significant drawback: the mini-shell can be either too soft or too hard. Worn in the pockets, a set of rubber washers of different hardness — a luxury.
Every thing in the house requires a certain space. Updated your library, increasing the number of objects or devices for work and leisure — in each case the problem arises of their placement. As one of the solutions to this problem can serve as a makeshift rack simple but original design.
In Amateur practice it is often necessary to assemble temporary circuits and soldering details “stuck” (as a welder). While in one hand the wizard tweezers, soldering iron in the other; item, to which it is necessary to solder the other element or conductor, “spinning” on the table: — need a “third hand”. Proposals on this subject abound in scientific and popular technical journals. For example, in the form of two clamps mounted on a tripod, or gum, and then just a small grip.
To race around on skates at a speed of about hundreds of kilometers per hour, it is not necessary to have some special sports data or gigantic physical strength. “Tailor” yourself “wind coat”, and you will achieve this without the use of any significant physical effort.
I want to share with readers the experience of recovery separator sealed bearings in the field of wire inserts for the distribution of balls in the clip with the desired step. This will help prolong the lifespan of many machines and mechanisms without removing and replacing the bearings. I ran into this when, after several years of operation of the drill in it was destroyed separators sealed bearings of the rotor of the motor.
In recent years, individual housing is a kind of “silent revolution”. Increasingly, private homes, whether villas, farmhouses or country cottages — built two-and even three-storey.

It is intended for the instant fixing of parts of circular cross-section axes, rods, rollers and the like. It can be used when drilling the end holes, milling flats, slots, or splines. The clip comes to the rescue and in the metal machining as it can be conveniently mounted in a vise. Another advantage of the device — a reliable fixation of the parts during processing.
