A master homebrew, working with metal, have in their Arsenal, angle grinder, called colloquially the “grinder” (the name originated in the old “stagnant” times, due to the fact that this power in the USSR were exclusively Bulgarian production). The undoubted positive qualities (high performance, ease of use, versatility, etc.) have angular shlifmashiny quickly wear out and even break the teeth of bevel gear pairs. To acquire the right set of gears and to sort out the gearbox — no problem. However, this does not relieve further from repeated repairs. It’s all about the grease, or rather in its failure. In the process of thick grease under the action of centrifugal forces distributed over the walls of the casing, divided into sectors by ribs, and thus out of business.
INCREASE THE RELIABILITY OF THE “GRINDER”
Present Board milling machine come in handy craftsmen who love to work with wood to get the blanks embossed surfaces, various geometric patterns, as well as cutting slots, grooves, sockets (both simple and shaped), etc. the Machine consists of two main parts: a base attached to it the guide posts and spring-loaded platform on which is mounted an electric motor.
Soldering metal tin solder — one of the most common but, unfortunately, the connection is not too strong. A more reliable seal provide so-called “hard” solders — silver-copper or copper-zinc. Most often, when brazing use a gasoline blowtorch. However, they should be treated skillfully: the lamp is unsafe in the fire relation, smokes when running, the flame is poorly adjusted.
Currently in stores you can easily buy any necessary household products. At the same time, attention and creative efforts of Amateur designers more going on technically complex objects: tractors, ATVs, cars and even airplanes. Changing the homebrew approach to the implementation of the projects; they are not afraid of the need for self-production of complex and accurate parts, which moreover may be subject to strict requirements in terms of strength. One such typical elements present in almost all energy-intensive structures, are cylindrical helical extension springs or compression. In this regard, many of our readers will be interested and, hopefully, it is useful to get acquainted with the methodology developed by the Ukrainian engineer Vladimir Vinichenko, which will help the responsible production of springs with the required quality and accuracy.
Rust metal, faded over time, brickwork, lost look painted surface… In all these cases is taken sandpaper or a metal brush — and stop! In the direction — is the last day! The lion’s share of tedious work in the clean-up should be given to the mechanism of the electro.
This machine will be your helper, if you’re into modeling or just like tinkering. Even at home, you often need to cut the rail and otfugovat it or sharpen tool — all these operations “on the back” made by me machine. It’s small — the dimensions 80X180X360 mm, so it is convenient to store in the apartment.
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.
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.
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.
