79. MEASURING AND CUTTING SHORES WITHOUT A BATTEN. If a shoring batten is not available, measure the
shores for length by using a folding rule or a steel tape and a carpenter's square, as follows:
a. Measure distance A (FIGURE 72) from center of strongback to deck. Then, measure distance B from edge of
anchorage to bulkhead, subtracting thickness of strongback.
FIGURE 72. Determining Length of Shore.
b. Lay off, on a carpenter's square, measurements A and B, using ratio of 1 inch to 1 foot.
c. Measure the diagonal distance between A and B. In the example given in FIGURE 72, this distance is 77/8
inches. The distance in feet would be 77/8 feet, or 7 feet 101/2 inches. Subtracting 1/2 inch for wedge space, the
required length of the shore is then 7 feet 10 inches.
