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 log clamp.
3. Make first cut, then remove slab from log (see
Figure 35).
4. Lower blade the desired thickness of lumber
and cut first flitch (see Figure 35).

5. Rotate log 180° and secure with log supports
and log clamp (see Figure 36).
Note: Logs can be live sawn from top to bot-
tom without being rotated, but rotating once
provides a stable base to saw the rest of the
log.
6. Continue to cut flitches from top to bottom
until log is fully used. Adjust log supports and
log clamp throughout process to keep log
secured and supports below blade.
7. Edge flitches as needed.
— If available, an edger can be used to
quickly and easily edge lumber.
— Without an edger, the sawmill can be
used. Refer to
Edging on Page 29.

Note: Live-sawing a square cant will produce lum-
ber than does not need to be edged. However, it
typically produces more waste than live-sawing a
log and edging it..
