Cut all four pieces for
the box to the exact
dimensions of the final
unit.
Make sure ends are
perfectly square and exact
widths.
The workpieces are
clamped together for the
cut. Ensure the workpiece
face sides are towards the
front of the jig.
Before joining the actual
workpiece make a trial cut
in waste scrap timber.
Box Joint Waste
Piece
For box joints, the waste
piece must be 5mm thicker
than the work piece. It
should be long enough to
be held securely by the
clamp bars.
The width should be at
least 5mm wider than
work piece. The waste
piece reduces likelihood of
breakout.
