In the modeling practice is often necessary for the creation of ellipses of various sizes, with different ratios of semi-axes. There are several ways of constructing such figures. But they are not without drawbacks. Well, I offer reliability and simplicity. However, the required pantograph is a device well-known to widely used. Moreover s requires no change in its design.AT FULL SPEED
Modelers working in rezinomotornaya know what it means reliable set of threads of the harness. This operation is generally performed in pairs: one holds the folded ends of the stretched rubber bands or thread, the other’s wrapping the joint.

When dressed flange with seals on the axle, wrapped with any fabric and impregnate any paint in several layers. Bushings on a “leg up” – saylenbloki with “Fields”, inner tube.
