Try to cut multiple identical workpieces on a lathe. How many times have to use a caliper! But if you make for his Studio, universal focus, the workpiece will turn out one in one — and without the frequent use of any measuring tool. Arranged focus just. In the tool post of the lathe near the cutter secured using a steel strap with a screw hole, in which is wrapped a screw. He will serve as a measuring stop is enough to set it to the desired size and fix it with the locknut. Now, to cut the workpiece of a given size, the rod from the holder just forward of the machine until it stops at the bolt head.UNIVERSAL STOPS

Vocational school graduates, finishing school, to protect diploma. They are often self-development: engineering and manufacturing of complex parts, assemblies, or fixtures. Cartridge-machine — theme of the graduation project of the former student of vocational school № 40, now training master M. Arkhangelsk.
Usually a heavy box, container or pallet with a load attaching to a lifting mechanism using four ropes-slings; lumber, pipe of large diameter it is possible to raise two. If you overwhelm sling loop-the loop, the normal load will rise and it one. Well, if you want to move, say, heavy sheet metal?
When my family moved to is not a new manor house with land, I faced the problem of its thorough repair and erection of outbuildings. It was clear that with only hand tools this kind of work will not do. And therefore decided before you start construction, along with concrete mixer, to make at least a simple woodworking sawing-planing machine, called artisans “circular saw”.
The need for large apertures of various diameters occurs very often. Some cut them with a jigsaw, others use a drill and then sanded the edges with a file, others are turning to so-called centraliza — fit to a normal drilling machine.
The coil is the most convenient form of packaging thin sheet materials and for the transportation and storage in warehouses. Foil, a synthetic film or paper in a tightly collapsed become a monolith, convenient in handling and are not particularly suffering from the hard grips of different mechanisms.

The idea is to make the jigsaw came to me many years ago, but brought it to life much later — when I got someone thrown the faulty sewing machine production Podolsk factory. From the “inside” machines only took the main shaft and the node of the “needle bar”, and other parts dismantled. Cut and the front part of the platform, leaving only a foot under the bar of a G-shaped case. On the sandpaper I ground off all the tides on the lower surface. The bearing at the corners of the drilled hole and through them, inverted the machine was attached to the top of the pedestal bottom. By the way, the Cabinet is also used from the old foot-operated sewing machine. However, to find such a Cabinet should be harder than the machine itself. But it may or may not be made of chipboard with 20 mm thick Top cover closed steel sheet thickness of 1.5 mm (and dural).
Creating some kind of mechanism or tool, the person usually by its name defines its main functional purpose. So, saw, saws, drill — sowing, the hole punch punch holes, and, say, a wrench used for screwing or unscrewing the nuts.
These two even look something like a high-performance tool developed by young innovators Dmitrov excavator plant. Brings them closer, and purpose: making large-diameter holes. The difference between constructive because they are intended for use with different materials.
