REZINOMOTORNAYA, CONTOUR

Usually, it often happens that the outwardly unprepossessing models-silhouettes start your journey in technical sports boys. After one or two procopii, they are taking with them part in her first competition and… don’t remember about contour, as we approach a much more sophisticated technique. Therefore, it is rare silhouette microcodable worthy of attention: because most often they come out from under too inept students.

But the appearance and contour of the model, and its driving characteristics largely depend on fabrication technology. Typically, the basic material used plywood medium thickness. Namely with her, and are associated main problems: the main tool of processing of the contours of the jig — saw, contact with which on “you” guys learn how only a couple of years. So now, when it is not so difficult to provide a circle of foams of good quality can be recommended to move away from traditional technology and use of the foam. Of preparatory operations should be undertaken only cutting boards on “Board” with a thickness of about 5 mm and polishing their surfaces.

 

It should be noted that the cutting contour of the ships of these billets becomes a pleasure with very good directional tool — polished knife with a sharp narrow blade. But the results are higher than those of plywood. Moreover, the foam — material pliable, and a little know how boys manage to make of the individual parts add-ins, tubes and towers. Even beginners can offer such a complex and seemingly busy copies, one of which is as an example shown in the figure.

1 — bow bracket rubber motor, 2 — hook with the curved retaining feature when moving forward to have a rubber tourniquet, use a drill directly on the model 3 — the wiring of the rubber motor, 4 — power beam engine, 5 — horizontal plate-circuit (“top view”) housing, 6 — contour image of the topside of the ship, 7 — rear bracket rubber motor, 8 — the side-wheel, 9 — the main Central wheel, 10 — wood insert for mounting the wheel and bracket, 11 — trim plate-contour “top view”, 12 — foam part 13 — bow insert for the mounting bracket.

Drawing on the bare foam is better not to move: a drawing made on thin paper or tracing paper is fixed on the workpiece in several places on the “points” of PVA glue outside of the working area. Cutting is conducted along with a paper detailing drafting drawing. The outer surface of the silhouette after Stripping of the contour in the right places podsalivaya and is painted with oil enamels. In this way it is easy to make and “top view”. However, before painting it is useful to turn over fake veneer, sliced into strips of appropriate width.
