When repairing thin lines (such as a car or refrigerator), it would be good to have on hand a small pipe cutter, and for connection of pipes with swivel nuts — device for rolling. Not hurt in a home workshop and a small vise. All of these devices can be made in the form of a set of interchangeable tool based on a simple clamp of suitable size (or specially manufactured). The design will need slight modification for mounting of tools for different purposes. In the first place must be milled afterwards the groove under all replacement fixtures (cage support rollers, rolling, vise) and drill a hole for the stopper.

Those who had to work with small parts, you know how hard it is to drill holes in them, the axes of which would be strictly perpendicular to the plane. The slightest imbalance leads to marriage, and often to breakage of the drill. Even the holes are not cylindrical in shape.
The proposed transformable workbench can be used not only at home but also in workshops, at stations of young technicians; “fit” it in the garage.
The scroll saw is a common tool. However, when working with him, guys sometimes faced with certain difficulties: the blade breaks, POPs out of the clips, if the cut on a curved path is often twisted, making it difficult to maintain the required direction.

Hams often have to drill into circuit boards of a large number of holes of small diameter. To do this a serial drills is not very convenient — too big size. And slim drill not so easy to squeeze in a larger cartridge.
Not long ago I discovered, in his home workshop old Microdrive MK-12-In, preserved, apparently, since childhood. What to do with it? Throw a pity, and here decided though somehow to use.
Osnova difficulty in creating a homemade drilling machines — making mechanism of vertical movement of the working body. What if you make a machine entirely without the mechanism to serve Chuck with a drill bit, and the item itself? In this case the structure is greatly simplified. No claim to originality for his decision, but it is this idea that allowed me to design and manufacture the machine, the device which is shown in the figure.
Novice hams are often hesitant to begin the Assembly of electronic devices just because in the description is missing the picture of the PCB, and to develop its own not everyone can. Indeed, without sufficient experience to make it easy: it is necessary to know how to choose the best dimensions to correctly place items in a timely manner to detect and correct errors. Therefore, we recommend you to master the design of printed circuit boards with the simplest.
This simple device can be useful to the house master in the manufacture of various frames, boxes, lampshades and other articles made from organic glass sheet, thermoplastic plastic or foam.
