Military aeroplanes; an explanatory consideration of their characteristics, performances, construction, maintenance, and operation, for the use of aviators . d warp thewing out of shape.

Assembly and Alignment by Cross Distances. The several steps in the assembly are indicated by referring to thesketch on p. 124. To begin with, the center section of wing over thebody, is set over the body, on the four small struts. The first step inalignment is to make this center section parallel to the body and centeredover it. Since the body is lined up, and the section affa, is a parallelo-gram, it follows that the cross distances, indicated as af, may be madeequal, in order to center up. When this is done for both front and reartrusses, the center section is bound to lie parallel to the body axis, provid-ing, of course, the distances were measured between symmetrical points. 124. u^ur. Diagrams for Alignment. It then remains to adjust the front and rear wires until the section hasbeen ])ulled forward or l)ack, so that one measurement fa agrees withthe similar one on the other side of the body and with the data on themachine. But these wires should not be tightened up until the wingsare on, in order to give pla> for the spar fittings of the wing the center section is somewhat near centered, however, difficultywill be found in fitting the rest of the wings. The next step is to fit thelower wings on either side to the body, and to hold them up by meansof their landing wares, fastened to the proper fittings at aa, but nottightened up. The top wings next to the body are then fastened to thecente
