Everyone who had to drill holes using a hand drill or a hand brace, knows how difficult it is to keep the drill bit in the desired position (usually perpendicular to the surface of the workpiece). In many cases, to avoid such difficulties helps homemade machine hand drill.
Its design can be like this. Thick wide stand mounted vertical stand with two guide rails. In the grooves of the rails easy to move the strap connected to the Shoe (“slide”), to which by means of a metal strip is attached to the body of the drill.
MAGNETIC PROBE WITH ALARM
Of the readers who didn’t lose metal parts or tools? Sometimes it happens at the most inopportune time and threatens to permanently stop work. Lost somewhere in the grass screwdriver that fell behind the Cabinet chisel or a failure in a pier of pliers is able to ruffle anyone. In such cases a simple device – a magnetic probe with light and sound alarm. Using this simple device, you can easily find the loss in hard to reach places and the fact findings you will be notified outbreak warning led and buzzer. The principle of operation of the probe is quite simple – on a long rod fixed two magnet “sticking” to the metal object which closes the circuit and lights the warning led. Thus, you can know when the probe with discovery, you can extract the “light”.
APPLES INSTEAD OF… UNDERWEAR
Fans of Apple juice can offer simple to manufacture and does not require significant investment homemade juicer. It is made from an old washing machine.
The factory extractor has low performance and poor reliability, because they contain a lot of plastic parts. In my homemade bucket of apples processed in 7 – 10 minutes.
For its production we will need from washing machine is mainly drum and its casing. You can rent them from either end washing machine with horizontal loading. To get such a machine nowadays is not a problem, since models change every 2-3 years.
BRONZE SCULPTURE
Bronze is the oldest metal alloy known to mankind. It is ideal for casting works of art because in molten form fills everything, even the most minor deepening of the form. This allows the sculptors to capture the smallest details.
According to the modern view, for the first time man learned to cast products from metal in about 3500 BC, in the era which is called the bronze age. Many civilizations created sculptures of their kings and gods. As for art, the masters of bronze sculpture was the French sculptor of the late 19th century Auguste Rodin. Said that in his sculptures more life than those they portrayed. Bronze is widely used in contemporary art.
Ball BEARINGS
In the world of modern industrial production on a prosaic bearings start to forget. However, for rotating parts of virtually any desired mechanism ball bearings. They are in household appliances, factory machines and even car engines.
On the video you can see deep groove ball bearing with deep groove. It steel balls move along the slotted rings of solid steel. The balls are made of the same steel.
TANK SU-122
TANK SU-122. Scale model 1:25.
Self-propelled gun SU-122 was developed in November 1942, the design Bureau of UZTM under supervision of L. I. Gorlitskiy. Leading engineer of the car was N. In. Kurin. A sample of the plant (factory designation I-35) was made on November 30, 1942 After the factory test, in the first half of December of the same year self-propelled unit has passed the state tests Gorokhovetsky Anope. On the arms were adopted on 5 December 1942 the Serial production started in December 1942 and lasted until August 1943 and All were released 638 self-propelled guns.
CAR PLOWING
Motorists that have a cottage or the HOMESTEAD, in the spring together take up the shovel on par with car-free part of humanity. Meanwhile, they could avoid such wastage of own physical effort, shifting a significant part of them on your car.
THE TRUCK WAS A TRACTOR
I’m a longtime, or rather, hereditary subscriber of the journal “modelist-Konstruktor“. First (1972) the journal was written by my father – Galkin Grigory Petrovich (he is now 80 years old), and then myself. Since the beginning of the output of the app “Aviacollection” – sign on him.
How many can remember, our yard has always been the vehicles. Love for her father has passed and my brother and me. In his youth are still fascinated by aviation. Under the influence magazine chose and the profession: graduated from Vyborg technical school and got the specialty of aviation mechanic. Worked for 21 years with a touch of 7,000 hours of on-Board engineer for the Mi-8 helicopter in the far North.
At the end of 1990-x years the father retired (although he worked another 7 years – 8 at the request of the leadership – he was a good crane operator). At the same time he built the tractor, so that it can serve the readers of “M-K“.

HIGH-SPEED PROCESSING AND MODELING
Three-dimensional, or 3D printer is the output device a three-dimensional data (typically, three-dimensional geometry). The result is some physical object, the prototype.
There are several 3D printing technologies, but the basis of any one of them is the principle of creating a layered solid geometry.
The principle of operation of 3D-printers Z Corporation more similar to a conventional inkjet printer. The main difference is that instead of applying ink from the printhead to the next sheet of paper into a 3D printer binder through the printhead is applied to another thin (about 0.1 mm) layer of powder, creating a single cross section of the object.
