The proposed model has a classic pattern glider A-2 “Hawk” in a reduced form. The main material for its construction – balsa. I must admit that over the last three or four years, such constructions appear frequently in competitions of any scale (though the schoolchildren they are made of more affordable material – to-ceiling foam). A return to this scheme due to the stability of the flight of such a rocket plane. Except only on the runway (starting) station.
This elegant Desk lamp is enough to have two rods with a cross-section 12X12 mm, length of 480 mm and three cubes of appropriate size. The most suitable material for this purpose is beech or birch. Good rails out of plywood in the thickness 10 — 12 mm.
Currently to build a sauna from a variety of building materials offered on the market today. The main criteria influencing the choice, become their own preferences, financial capabilities and experience with a particular material. A private bath may be the embodiment of your design decisions.
On the border of abandoned orchards, in a thicket of nettles, accidentally discovered the old axle with a pair of wrought-steel wheels – the remains of the village hand truck waited in the wings. Excavated and cleared of earth and grass rarity brought home and presented to the “home of the Commission on restoration.” It was decided to restore the cart-a cart to original appearance.
Simple and beautiful ball-point pen can be manufactured in a few minutes, if there is a rod with pasta and… a colourful illustration from a magazine or just a sheet of paper. For this purpose the attached drawing is cut out of the billet that the part A is screwed onto the rod. A large part of the workpiece (dashed line) are pre-lubricated with glue AK-20, BF or white synthetic, giving a flexible joint.
This car is well known to motorists. She enjoyed a well-deserved recognition among agricultural workers, geologists, soldiers, builders. For two decades she was on the production, which in itself is a clear proof of how successful was the design of the GAZ-69.
Pikirayi bomber SBD DAUNTLESS. In 1934, the US Navy announced a competition for the creation of new carrier-based dive bomber, according to the American classification — scout-bombarde-Rossica (scout bomber). The main requirement for a new aircraft — a significant increase in speed compared to BOM-Bardi rustami predecessors. Bomb load was to be placed under the fuselage on a special suspension unit with a catapult device, which provided a safe separation of cargo at high speeds during the dive. The fleet was ready to consider any proposal, regardless of the aerodynamic configuration and other characteristics of the aircraft.
Cut or broke off and remained in the hole pin or a tap when cutting threads in cast iron or aluminum parts — it is unpleasant, but not hopeless. Rescue proven the following simple technology: the hole reams a larger diameter, allowing not only to remove the chip, but to cut a thread and screw stem nut on new stud or bolt.
“beats” the beats not only sound, but light pulses. In his scheme includes two transistor of different conductivity. The excitation amplifier is implemented by using positive feedback through the capacitor C1. The pulse repetition frequency — from 40 to 210 per minute — adjust the variable resistor R2. The amplitude — adjusted with resistor R5.
Mirage IV was created in France as one of the elements of the nuclear triad. The prototype took to the air in June 1959. Produced at the company “Dassault aviation” in 1963 -1968 years, total built 66 units in the nuclear bomber and reconnaissance.
