When flatting a workpiece of more than 75mm thickness the bridge guard must be lowered on to
the table and adjusted horizontally to the workpiece. The workpiece should be straightened,
with flat hands beside the guard, along the fence.
Foot positioning
It is important that a good
firm and balanced base is
made and maintained by the
feet during planing. The feet
should move forward with the
work piece giving good control
of
the

9.3 Planing Bowed Boards
Slightly bowed boards may be planed by the method shown below, but care must be taken to
ensure two point contact on the infeed table to avoid throwback. Badly bowed boards should
not be planed in this method and should be cut up for jobs requiring shorter lengths.
Always plane the board hollow side down, as shown
Working round side down causes timber to rock,
thus making it very difficult to obtain a straight parallel
face.
