To check the symmetry of the punch of a model of the ship on the drawing manufactures all of its frames (or polosamote). Although this work is easy, but requires time and material cost. For ship modeling clubs and laboratories, which launched production models of ships of various classes, I suggest using a universal mechanical pattern. It reliably and quickly provides control of compliance with the hull lines of the model of the vessel its theoretical drawing and defines even the most minor asymmetry to each side of the punch.WITH COTTON — TIGHT
The surfaces are usually not only previously degreased, but cleaned with sandpaper to get the roughness that increases the strength of the connection. The same effect can be achieved if between the abutting surfaces to lay impregnated with glue a thin layer of cotton wool: it will increase glue area and grip will get stronger.
In the journal “modelist-Konstruktor” was published an article by a teacher from the city of Severodvinsk Vladimir Arkhipov, dedicated to the manufacture of plastic fine-grained cylindrical gears for motor car, ship and plane models on the example of gear made of polyethylene with the basic settings of m = 0.8 mm and z = 8. Continuing the theme, the author offers the readers a mold similar to the previous one, but with one fundamental difference — it is designed for making small batches of disc gears with the end location of the tooth.
This area may be under the stairs not only in the country with an attic, but in the modern duplex apartments as living room and kitchen downstairs, and bedrooms upstairs. And usually this “Appendix” is seldom used as such, even a small space can be equipped diligently and thriftily, and, as evidenced by the Polish magazine “Throb himself”, is available for solo performances of pieces of furniture. The more that trade provides such a convenient and non-deficient materials, such as particleboard, furniture Board, wooden bars, wooden boards, slats, which can be treated with the usual household tools such as a hacksaw, drill, jigsaw, chisels, and screwdrivers and, of course, a hammer.
“If we turn the pages of aviation history, you will find that most modern aircraft as heavier than and lighter than air born motorless aircraft were gliders, airships — balloons. Motors came in the process of evolution. About the same we are seeing now in hang gliding: after the glider to a pure glider version began intensive work on its “motorization”. They were conducted in parallel, both Amateurs and serious scientific institutions, aircraft manufacturer. And got results that suggest that in the near future, the trikes will become an independent unit of the aircraft. This is evident, in particular, a recent flight on an ultra-light aircraft across the English channel from London to Paris, in the ways of the early aviation pioneers. At last year’s aviation show in Le Bourget has demonstrated the device “Metadata”, produced in Germany. The machine flew well. No doubt that experiments like performed by S. Belikova, deserve every poderina, first and foremost, the Federation of hang gliding sports of the USSR”.
