68 Australian Wood Review
TECHNIQUE
After this, or if your board is only mildly cupped or
twisted, you can now take a mid-sized plane set for a heavy
cut (a No.5, 6 or 62 would be perfect) and start by taking
cross grain shavings directly across the face of the board.
This will quickly bring the high edges down to the concave
centre of the board (photo 3).
You can either boldly mark the face with a crayon to
determine when you’ve reached the end point, or you will
quickly feel and hear when you’re taking full width shavings
across the board. You can also use a straightedge (such as
the edge of the sole on your plane), to visually check your
progress (photo 4).
Now to actually flatten the face you’ll need to take an
overlapping series of diagonal shavings that will traverse
the full width and length of the board as shown on p.66.
Then switch your approach and repeat the process, taking
a set of passes on the opposite diagonal.
Once you’re taking full length, full width shavings for a full
set of passes, you can check your results with a set of winding
sticks (photo 5). I’m using traditional handmade sticks, but
straight lengths of aluminium angle from the hardware store
will achieve the same result. Use the deviation of the sticks to
identify and highlight any remaining high points and target
those on your next set of passes.
Once your face is perfectly flat, I typically take a longer
No.7 but on the smaller board that I’m working on for this
article I’ve chosen a No.62. This is now used to remove the
diagonal plane tracks. Work in overlapping passes along the
longitudinal length of the board. Once again, the goal is
full length, full width passes (photo 6).

- Removing the high
edges of a cupped
board by taking cross-
grain shavings. - The edge of the sole
of a quality plane is a
handy straightedge. - Winding sticks are
perfect for checking
flatness and the
absence of twist. - Remove the diagonal
toolmarks with
longitudinal passes. - A finely set smoothing
plane will finish the
process. - Taking full-length
shavings to dress the
face edge. - Using the sole of
the tool to check
straightness.
