Building solutions, lubricating oils, protective fluids, paint, varnishes for coating of many modern “self-leveling” materials require special spray tips.
The machine is attractive for its versatility. It must be equipped with protective devices. Over the slot in the table it is necessary to install a height-adjustable pressure roller. Then Board when planing stops to jump and escape from the hands of: the quality will be better and fingers — safer. Of course, we cannot forget about the protective fence of the saw blade. And again. Because jaw Chuck is not moved, feeding parts for drilling, obviously, have to manually. To mechanize this process is also useful.
This fixture is also from Kazakhstan. It was designed by the tenth of the city of Shymkent Pinhasov Sergey and Valery Dubinin. Designed the mechanism to define the groove mortise door lock. The device is actually a small milling or, more precisely, tenoning machine, assembled on the basis of the drill. As with milling, it Read more…
Modern engineering makes high demands on the materials, and they, in turn, to the machining tools. Not by chance all the exhibitions NTTM necessarily demonstrates the new development of young innovators dedicated to solving these problems taking into account the specifics and requirements of each specific production, and often cross-sectoral in nature.
I’m a subscriber “Modeller-designer” already since 1972. Much of that time has changed, but the content of the magazine, I (and not only me) are quite satisfied. Let increased its subscription price (which is of course not pleased, but not scared — I understand the difficulties of the editors), I’ll write a journal, yet it will exist. Not going to list those topics in it that interest me the most is all that can be done in a home workshop, ranging from simple stools to, for example, motoriety. I also do many things with their hands (friends call me by this “local Kulibin”).
With it easy to turn tightly wound cover and the clutch. In this tool, as the tape uses a rubber strip with a thickness of about 3 mm, width 22 mm and length of 450 mm. If you want to use the key for the caps of large diameters, respectively, and increased the length of Read more…
In technical circles often there is a need for a wooden workpiece, having a flat, smooth surface. To ground the Board easy manual processing is laborious and requires specific skills. The machine, designed in the laboratory, missile and space simulation CSUT of the Kazakh SSR, allows to mechanize the grinding of wooden parts. The design of the machine is clear from the figure. Used to the drive motor of the brand AOL-21-4 power of 0.27 watts at 1400 rpm, but you can use any other motor with similar characteristics.
Blades from the safety razor is often used as a kind of microcycle. But keep them in the hands uncomfortable and unsafe. Holder, shown in the figure, will significantly simplify the business. The handle can be made of aluminum tube with a diameter of about 12 mm. One of its ends flattened and bent at a comfortable work angle. It bent the end of prikladyvaya steel plate, which split three threaded holes M3. Wrapped in two outer screws, and their heads serve as guides when installing the blade.
Many probably had to watch as the metal is heated during processing it on an emery wheel. The phenomenon is harmful: heating “releases” hardened metal. Is it possible to turn it to their advantage? Well, for example, to cut metal? For the experimental verification of the idea took only an hour and a half I’ve ground off the teeth from an old circular saw blade and secured the tool (smooth disc) is grinding in elektrotochilo.
This device allows you to consistently perform those operations which are performed simultaneously jigsaws, tension and clamp the blade. It is especially difficult to learn this kids — those who are just starting to learn this tool. The essence of the device in the following. On that machine, the jigsaw is pivotally secured the strap Read more…
