Cross Pieces for Rudder Beam.
To do this he should begin by putting in a cross piece, 2 feet long
by 1/4 x 3/4 inches between the center struts, in the lower
plane. This may be fastened to the struts with bolts or braces. The
former method is preferable. On this cross piece, and on the rear frame
of the plane itself, the rudder beam is clamped and bolted. This rudder
beam is 8 feet 11 inches long. Having put these in place duplicate them
in exactly the same manner and dimensions from the upper frame The cross
pieces on which the ends of the rudder beams are clamped should be
placed about one foot in advance of the rear frame beam.
