Underbucking
Begin on the underside of the log with the
top of the saw against the log; exert light
pressure upward. During underbucking,
the saw will tend to push back at you. Be
prepared for this reaction and hold the
saw firmly to maintain control.
◾ ◾
When the log is supported along its
entire length, it should be cut from
the top (overbucking) (Fig. 19).
◾ ◾
When the log is supported on only one
end, cut 1/3 the diameter from the
underside (underbucking). Then make
the finishing cut by overbucking to
meet the first cut (Fig. 20).
◾ ◾
When the log is supported on both
ends, cut 1/3 of that diameter
from the top overbuck. Then make
the finished cut by underbucking
the lower 2/3 to meet the first cut
(Fig. 21).
