Live Sawing
Live sawing is a method of sawing logs that is fast
and produces very little wasted wood. In a live
sawing procedure, the log is cut from top to bot-
tom and is rarely rotated more than once.
Lumber produced when live sawing will range
from flatsawn (cuts made near the top and bot-
tom) to quartersawn (cuts made near the middle
of the log). Because no specific type of lumber is
prioritized, live sawing maximizes the amount of
board feet produced per log.
To live-saw a log:
1.
Inspect log and outline a sawing plan.
Consider orientation of log on track and
where to start cutting to produce the best
lumber. Mark planned cuts on end of log.
2.
Load log on track bed and secure with log
supports and clamps.
3.
Make first cut, then remove slab from log (see
Figure 84).
4.
Lower blade the desired thickness of lumber
and cut first flitch (see Figure 84).

5.
Rotate log 180° and secure with log supports
and clamps (see Figure 85).

Note: Logs can be live sawn from top to bot-
tom without being rotated, but rotating once
provides stable base to saw rest of log.
6.
Continue to cut flitches from top to bottom
until log is fully used. Adjust log supports
and clamps throughout process to keep them
below blade and to keep log secured.
7.
Edge flitches as needed.
— If available, an edger can be used to
— Without an edger, sawmill can be used.
