Open-face technique
Making sapwood cuts
D = Felling cut
Conventional and open-face technique:
C = felling notch - determines the
direction of the fall
:
For medium sized or larger trees
make cuts at both sides of the trunk,
at same height as subsequent
felling cut.
:
:
:
:
Begin 1 to 2 inches (2,5 to 5 cm)
higher than center of felling notch.
For an open-face cut:
:
Properly place felling notch
perpendicular to the line of fall,
close to the ground.
Cut horizontally towards the felling
notch.
:
Cut to no more than width of guide
bar.
Leave approx.1/10 of diameter
uncut. This is the hinge.
This is especially important in softwood
in summer - it helps prevent sapwood
splintering when the tree falls.
:
Cut down at app. 50-degree angle
to a depth of app.1/5 to 1/4 of the
trunk diameter.
Do not cut through the hinge - you
could lose control of the direction of
the fall.
:
:
Make second cut from below at app.
40
degree angle.
Remove resulting 90-degree piece.
