Modelers know how difficult it is to facilitate fine rib, without violating its strength. In the model airplane circled our House pioneers a way of cutting out successfully replaced the cutting. This causes the strength of the part and the work is done much faster. Hole punch tubes of different diameter, with the end sharpened on a lathe (a type of punch or die-cutting). This method is acceptable not only to facilitate the ribs, but also in the manufacture of the fuselage, and keels in many other parts. A. BUYANOV, Taiga
