Fixture is used for manufacturing propellers boat on lathes Тb-4 and TV-7. Using the tool it is possible to produce propellers of aluminum alloy (D16T), brass and plastics. Moreover, the production of screw blanks of alloy D16T takes up to 10 minutes, and made of brass — up to 40 minutes. The diameter of the screws up to 50 mm Number of blades — 3. You can do two – and four-bladed screws, but this requires modification of the spindle and tracer. The fixture consists of a housing, which is attached to the copier. In case the spindle is inserted, it is secured to the arm and disc. In a lathe Chuck clamped to the mill.
…Already left behind a crucial period of the war. Vienna, like many Austrian cities, a lot of bitter’ve seen over these difficult years. Destroyed the magnificent palaces and buildings, and striking in its beauty of the bridges in the centre of Vienna there was only one “Imperial”. Yes, and it is now given purely strategic value — now only it connects the two halves of the city between them.The command of Hitler’s troops, based in the Austrian capital, could not know about the approach of Soviet troops, and therefore a lot of attention to the protection of the Imperial bridge. And despite this…
No matter what, the army of auto – and motor-fans continues to grow; it now joins a band of enthusiasts velomobiles transport. Much worse is the case with garages. However, they had remained a cherished dream of motorists and unattainable utopia of all others. Meanwhile, for the motor-fans and homebrew that creates micro cars, motorcycles and pedal cars, this problem is solvable. In particular, I managed to create a version of the garage… wheels, which can accommodate motorcycle, motor scooter or as me, a recumbent.
We are talking about different versions of electronic ignition devices (UEZ), is made as transistors and IC. The lack of scarce elements, as well as the simplicity of the schemes allow you to collect the block of electronic ignition even ignorant in electronics motorists. UEZ can work together with the ignition coil B-117 (B-117A) and B-115V, used in cars “Zhiguli”, “Moskvich” and “Zaporozhets”, and since there is no special transformer to storage capacitor, the device consumes virtually no current when the ignition is on, has small weight and dimensions.
Ten years ago I accidentally fell into the hands of the magazine “Modemist constructor” — and from that time on, I his sincere admirer and a regular subscriber. I can say that it is the only publication that I fully retain, often address to it and a lot of published use for yourself.
Today we offer young modelers rather unusual development of high-speed cord models apropriada. Novelty design in unusual approach to design. Perhaps this is an approach based on the full (but competent at the same time, taking into account all the important factors) simplification, truly perfect. For good reason, among these designers, there is a widespread saying: “a Difficult decision can find any, and to solve the task a minimum number of simple parts and assemblies — only genius.”
Currently a subclass of “school” high-speed cord does not Shine sport results. The competition clearly shows the separation of equipment into two groups. First, as a rule, are simplified “veneroida” contour type, which, if a young athlete is able to cope with the management, you can show only average speed, and even then with a good engine. The second group consists of devices created exactly according to the samples of a champion techniques (if not outright borrowing occurs). Do note that the gap between the two groups as the quality of the models and their flying capabilities, and initially decide the issues is very high. Poluchennye contoured speed are likely only tasks “to designate” the presence of this class at the event.
