HOW TO LOCATE THE PALLET ACTION.
With the parts related to each other as shown in the cut, to establish
where the inner angle of the pallet stone is located in the drawing, we
measure down on the arc _k_ five degrees from its intersection with _a_,
and establish the point _s_. The line _B b_, Fig. 90, as the reader will
see, does not coincide with the intersection of the arcs _a_ and _k_,
and to conveniently get at the proper location for the inner angle of
our pallet stone, we draw the line _B b'_, which passes through the
point _n_ located at the intersection of the arc _a_ with the arc _k_.
From _B_ as a center we sweep the short arc _j_ with any convenient
radius of which we have a sixty-degree scale, and from the intersection
of _B b'_ with _j_ we lay off five degrees and draw the line _B s'_,
which establishes the point _s_ on the arc _k_. As stated above, we
allow one degree for lock, which we establish on the arc _o_ by laying
off one degree on the arc _j_ below its intersection with the line _B
b_.
