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.
SPRING A BLUEPRINT
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.
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.
