SHIPPING, UNLOADING AND ASSEMBLING 45hold the inachiiie in the oar.Two lon^ plauks are placed from the doorof the car dowu to the j^roimd and are used to roll the machine ont ofthe car.Open ill (J})().i-es.—A screw driver and bit brace should be used to removethe screws in the top, sides and ends of the box. The top is removedfirst, then one side. All smaller parts of the machine should betaken out, after which the remaining- side of the box is removed, andlastly the ends.Asseiiihliitfj a machine.—The landing gear should be put on first.To do this the fuselage must be raised by one of two methods. The firstis by chain falls or l)lock and tackle. The rope sling should be passedunder the engine sill just to the rear of the nose plate. The tail of themachine is allowed to rest on the tail skid while the nose is raised. Thesecond method is by shims and blocking. This latter method is the mostcommon because chain falls are not always available. Enough blocksshould be secured to raise the fuselage high enough to slip the landinggear underneath. The tail is first raised l)y 2 men and blocks are i^lacedunder Station 5 or the rear wing section strut. The blocking must bedirectly below the strut and must have padding upon it. Then the tailis depressed and another block is put under the forward wing strut. Thisoperation is then repeated until the fuselage is high enough for the landinggear when the nmchiue is blocked under nose and tail and the otherl)locks are removed. Three or four men are all that should l)e requiredfor this second method.Assembling WingsAfter the landing geiir is assembled the center section panel shouldbe attached and approximately lined up. Then the wings are assembled.There are two methods for doing this; one is to put on the top i)lanes,place supports under the outer edges, then put in struts and lower planesand connect up the wires. The other method is to assemble the wingscompletely while on the ground. Wings are stood on their enteringedge, struts are put in and wires tightened up to hold the wing sectionstogether. Then the wings are attached to fuselage by turning them overand attaching the top wing first, then the lower wing. One side of themachine must be supported until the opposite set of wings is attache
