(2) The number and size of each piece
in a section is given to the man in charge of the
cutting party. The cutting party cuts the timber to the
correct length with a handsaw or power saw. The
length is measured by the use of square and tape.
After one piece has been cut, it may be used as a
pattern for marking the remaining pieces. The
pattern is set up by nailing two blocks to the piece of
correct size, one near each end, as shown in figure 5-
2. These blocks act as stops to hold the pattern in
place on the timber to be marked. Several cutting
and assembling parties may be used at one time on
different types of sections.
