 TM 55-1915-200-SDC
Section VI. APPLICATION OF SHORING
7-10. TRIMMING AND FITTING SHORES. Shores must be trimmed to fit the shoring structure, and the trimming must
be done in such a way as to prevent splitting or chipping of the shores. If shore A in FIGURE 7-3 is to fit against a plane
surface of shore B, and if it must take a load in compression, the end of shore A must be cut square and perpendicular to
the long axis of shore A. Sharp points must never be used when shoring is required to withstand pressure. FIGURE 7-4
shows the correct way to fit shores to present a flat surface at each pressure area. The carpenter's square can be used
to measure the angles of cut and to mark the shore for cutting. Shores are sometimes notched at the end to fit against
other shores, but this method should not be used if any great pressure is to be expected. A safer method is to cut a
socket in the side of one shore and fit the butt of the other shore into the socket. This method is shown in FIGURE 7-5.
