MODELING
Model skin imitation. Tips for a modeler
Directory / Radio control equipment It is good to imitate the fabric covering of aircraft from the Second World War on copy models as follows. On the model that has not yet been primed with white enamel, according to the drawing, we mark the axes and edges of the protruding rigid elements (ribs, stringers, edges of the edge of the junction of the rigid sheathing with linen, etc.). Then, according to the marking, we glue the "ribs" of copper wire Ø 0,15-0,25 mm. The wing, plumage, fuselage of a real aircraft are a power part with a rigid sheathing and a non-power part with a linen one - on the ribs of the ribs and stringers, the linen sheathing slightly "sags". Stretching along the markup the wire that reproduces the ribs of the ribs and stringers, we press and draw along it once or twice with a brush dipped in enamel, highly diluted with acetone. After making sure that the wire is grabbed, cut off the excess ends with a sharp cutter or a piece of a razor blade. Thus, all "ribs" or "stringers" are glued in succession. Rigid elements are simulated in the same way on the sections of the fuselage of the model with non-powerful "cloth" skin. Due to the long length of the "stringer" and, as a rule, poor approaches (often interfere with the plumage or wing), it is quite difficult to provide the necessary tension to the wire. In this case, the tension is carried out with the help of pins. The ends of the wire are fixed on the bases of the pins, stuck into the body slightly with an allowance from the points of the beginning and end of the "stringer". After gluing the wire with a sharp knife, cut off the protruding tips and remove them along with the pins.
Before applying the primer (white nitro enamel), the area with linen sheathing is isolated with a mask of adhesive tape, the shape of which must exactly repeat the geometry of the edges adjacent to the "linen" sheathing of the "rigidity" areas. After that, the primer is applied. The mask should be removed after sanding the soil. During subsequent painting, due to the boundary of the ground coating, a fairly clear visible edge of the rigid sheathing is formed.
On a model made, for example, on a scale of 1:50, the corrugation pitch should be 0,5 mm, and the width of the rib flanges at the junction of the skins should be 0,6-0,8 mm. The height of the corrugation is 0,1-0,2 mm. In the same way, the skin of the horizontal and vertical tails is also performed. To imitate the corrugation, first of all, it is necessary to carefully prepare the surface of the wing for painting and draw out the places of the ribs. It is necessary to apply the boundaries of the smooth sections of the wing ("forehead" - to the front spar and the tip), then a thin copper wire Ø 0,15-0,2 mm - "corrugation" - is glued onto the surface of the wing - "corrugation" - with the necessary step. The most suitable for this purpose is varnished wire from the coils of radio devices. The wire is wound evenly, coil to coil, so that all coils are parallel to the longitudinal plane of the model. We fix the first 20-30 turns on the selected section of the wing, previously lubricated with liquid enamel diluted with acetone. As soon as the entire necessary surface of the wing is covered with overcasting and fixed with a layer of enamel, you can "free" sections of the wing with smooth skin, carefully cutting off the excess wire along the marking, trying not to damage the fixed corrugation. Then, with the sharp tip of the knife, we “thin out” through the coil, carefully tearing off one or two subsequent ones, depending on the diameter of the wire. 3-4 wires are not thinned out at the joints of the skins along the shelves of the "ribs" - after coating they will imitate a wide "shelf" of the rib. The hatches on the wing had a smooth skin - we cut the corresponding sections of the corrugation with the tip of a knife to the level of the wing surface. Then this area can be sealed with a piece of foil. The resulting corrugation is finally fixed on the wing surface with three or four thin layers of liquid enamel. Each subsequent layer is applied after the final drying of the previous one. At the same time, it is necessary to ensure that the enamel lays down in a thin layer, without local streaks and accumulations - otherwise the wires in these places may come off. Use the softest brush, the direction of its movement is along the "corrugation". Author: O.Lagutin
