Figure 33. This is an example of a surface
planing operation.
Surface planing flattens the concave face of the
workpiece in preparation for surface planing on
a thickness planer (Figure 32). The flat face
allows the thickness planner to produce a work-
piece that is flat and uniformly thick.
Figure 33 shows an example of an operator
using the jointer to surface plane a workpiece.
Notice that the operator’s body is not directly
behind the workpiece and that the operator is
using push blocks.
To perform a surface planing operation, do
these steps:
1. Read and become familiar with the
Operation Requirements sub-section.
2. Place the workpiece so the concave side is
down on the infeed table and press the
workpiece firmly against the fence.
3. Start the jointer.
4. Using push blocks, feed the workpiece
through the jointing operation. Make sure
to maintain even downward pressure.
5. When your leading hand gets within 4" of
the cutterhead, lift the push block up and
over the cutterhead and place it on the
workpiece as it passes over the outfeed
table. Do the same thing when your trailing
hand gets within 4" of the cutterhead and
try to maintain pressure on the outfeed
table.
6. Repeat steps 4-5 until the surface is flat.
