In the processing of metal surfaces and finishing of the joinery is quite often used grinding sandpaper. It is usually navertyvajut on the bar, but they sandpaper wears unevenly, and cleared material remains between it and the surface, preventing their contact. In addition, a significant portion of the abrasive generally remains unused and is discarded.
(UNIVERSAL MACHINE). Replacement of manual mechanical tools is of great importance not only in manufacturing, but in the home work of the designer-lover, embodies with wood and metal in their designs. Sometimes even the most simple fixture, primitive stanochki significantly speed up the work, facilitate it and to dramatically improve the quality of the product. That is why in recent years an increasing number of miniature machine tools for processing wood and metal, designed for hobbyists and tinkerers.
One who is engaged in sawing wood, is constantly faced with difficulties and inconveniences that arise when a seemingly simple process — the clip blade in the jigsaw. Assistance here will have a fixture, the basis of which are the lever, bearing and clamp. All items are made from metal strips with a thickness of 2 mm.
In the practice of the house master, there are cases when you need to drill a large diameter hole, and nothing. In this case, will help improvised hollow drill bit, suitable for non-ferrous metals, plastics, wood. It leaves a cylindrical disc, which can also be used, and quite a bit of shavings.
DPJ-quality processing of wood of iron planers, chisels and other tools necessary not only to sharpen, but to rule. This is achieved by lapping on the touchstone — the operation usually done manually and require usually more qualified skills than sharpening on elektrotochilo.
In your journal repeatedly describes the various designs of devices for removing pressed on the shaft bearings, bushings, pulleys. I propose another option — simple in construction and quite versatile. This puller has become my indispensable assistant: allows you to avoid damage to parts during disassembly, making the work easier.
Machine UK-4 is still popular among hobbyists and tinkerers. Over the years of its release, home craftsmen invented many devices to improve its performance and broadening the range of operations. Many of these upgrades were reported in the “M-K”. However, nothing was said about using his motor at full capacity. But it is quite enough to handle larger workpieces than the number specified in the passport of the machine. And the need for such a feature: in this we have repeatedly seen at work in our model aircraft club. Here and was made a fixture that allowed to increase the depth of milling parts using standard cutters b to 17 mm with their width up to 260 mm instead of 60.
In one of the shows can viewers was submitted to design a universal machine, designed by the engraver of the suburban town of Troitsk Y. M. Orlov. Not only a discussion of a design program participants, but also by the numerous letters received by the author, editions, TV and the magazine “M-K” showed how great the interest was this table versatile machine capable of performing a number of operations for machining a variety of materials. To meet numerous requests, the editors asked the author designs to tell more about it.
Designed for parts that are in processing it is necessary to fix in an inclined position. Clip design is simple: to steel base welded corners-brackets; on a coaxial screw-clamps rotated box, which can be installed in a wide range of angles.
This device will serve you well — will facilitate the drilling of holes: in the grip gear grip force and a half times more than usual, which increases the reliability of fastening, and turn the handwheel Udinese than a normal pen. Changing pads (each of them attached to the jaws by two screws M8), it is possible to clamp items of different configuration Maksimalna thickness up to 80 mm. the design of the grip to the gearbox all the parts are quite simple, made of steel of common grades.
