Mother Russia is rich in earthly gifts. Among them not last place is occupied by precious, semiprecious and ornamental stones. One Ural! It is therefore not surprising that in Russia, many artists and fans involved in the processing of ornamental stones. And in order to do this successfully, little one desires and abilities – you need a special tool and at least a minimum of equipment; diamond circular saws and accessories for cutting ceramic tiles. However, there are two “but”. First, their application area is quite limited (e.g. diamond discs have a thickness of 2 mm or more, in many cases for cutting ornamental stones are not acceptable). Secondly, their value, to put it mildly, inadequate to the modest income of the average working Russians, especially pensioners.

Wood planers used in school workshops is simple, but it does not deprive one significant drawback: the imperfection of the V-mount glands. If mishandled she tries to slip out of a plane or obliquely to become in the yrs. Besides, it is necessary to learn how to swing a mallet to install it, it will not be adjusted tool.
For many operations performed in the training workshops and technical circles, very comfortable would be portable universal tool like dental drill. However, to acquire such is almost impossible, and, as always in such cases, the question arises: is it possible to make something similar on their own?
In most jigsaws, with whom I had to deal, there is provided a cantilever clamp blade relative to the mounting bolt (Fig. 1). Because of this, I think, often encountered distortions of the working body, and the canvas breaks down, not having served on time. And to release such a clip when changing the saw blade gave a hard, requires considerable force.
If a hardware craftsman himself makes various machines, such as small tools that facilitate work on the farm and in the home, then no welding machine he can not do. Among designers and fans of the most common machines, electric arc welding stick electrodes.
This compact machine on the basis of drills is intended for wood and plastics. It allows you to cut bruski, boards, plywood, plexiglass and the PCB, cut the slats and shaped plank, milled grooves, carve the wood, polishing surfaces, drill holes, sharpen drill bits, chisels and other cutting tools.
Offer DIY (and home) is a device for welding plastics. However, it can be used to solve a variety of problems of technical work — for example, to blow away solder from electronic circuit boards dismantled. Because the temperature coming out of the nozzle-tube air reaches 300°C, and warm-up only takes 5 — 8 minutes.
A device for sharpening cutters of the disk provides the necessary accuracy and uniformity of treatment of each tooth. It allows you to accurately fix the cutter relative to machine tool — grinding wheel. The fixture is mounted on the table of a milling machine and is fixed with two screws M8.
When working with metal often must bend, to stamp, to pull from sheet materials of different parts, figure out, puncture, cut them all kinds of holes. Such operations are performed with a press and set of dies. However, the study of the hydraulic press, commonly used for this purpose, has drawbacks: it is impossible to work with sheet material wider than 80 mm, it has no reverse enhanced speed, and the speed of movement of the piston is small. In addition to fixing tools special tools.
Often there are cases when you need to drill a hole to a predetermined depth. To do this, you will a simple device, consisting of three parts. The clamp-holder — mounts on the body of the drill. Two guide holes is inserted a stop, which is bent, as shown in the figure, from metal rod O 6 mm. During operation, the emphasis gradually moved into the holder until it reaches its locking (Fig. 1) fixed at a distance equal to the required drilling depth.
