There was a time when to the store to buy any device, especially metal cutting machine tools was difficult. And was expensive, and a run of outlets had. Today to buy such a product just just pay. But the homebrew is still not translated, offering a new design made based on their capabilities. With the technical creativity of Feodor Nikitovich, Kuhtenko our readers are already familiar (see “M-K” N° 6 – 2012). This time we offer the more complex its design – drilling machine, constructed primarily from what the designer had on hand, though without turning and milling operations has not done.
DRILL ON THE TABLE
The first thing that comes to mind after Novoselov obtain a warrant for the apartment – such as drilling holes in concrete walls, how to attach the hooks to the asbestos cladding? Meanwhile, a variety of designs, there are many traffic jams, and you will always be able to do any of them, taking into account the thickness and strength of the wall, its technical capabilities and the number of required hooks and screws. The simplest option – all known wooden plug of solid wood. Its cross section should slightly exceed the diameter of the prepared hole. Cork hammered with a hammer, then drill its center, thinner than the intended nail or screw, nasverlivaetsya hole.

People who ever interested in these issues, know the key-lock type “bolt of the sea” (perelamyvaniya bolt) — on the upper side latches or conventional valves cut teeth (grooves), into engagement with which includes the “falling” part of the key, and when you turn the last latch moved over. All is good here, but if necessary, and can be, and malice two or three attempts easy matching desired length of the free end of the key…

If the layout of the rural house or garden such that the largest room borders the kitchen, instead of the disparate sources of heat (conventional oven or the fireplace in the “hall”, and plates in the kitchen) it makes sense to build the complex furnace-fireplace-stove. In our farmhouse and made: all heat sources are connected to a single volume with a single tube (of course, alternately use it) that gives a noticeable savings of space and materials. Feature of the complex is that the fireplace is easy to turn to the oven and Vice versa. In addition, by manipulating the valve-mi-sliders from great room to heat the kitchen or, on the contrary, from the kitchen to actively nurture a warm room.
Externally, this padlock is no different from thousands of his fellows, keepers of the storerooms and garden sheds and utility rooms, stores and warehouses.
