Clamping Jointer and Planer Blades
Loosen the thumbnuts securing the three clamps on the jointer blade
sharpener. Position the blade with the bevel facing down under the
short legs of the clamps and lightly tighten the thumbnuts. Turn the
unit over and adjust the blade until it overhangs the edge of the jointer
blade sharpener body by about
shown in Figure 4.

Before you fully tighten the thumbnuts, slide them forward until
the clamp springs touch the rear of the blade. This increases the
clamping force, reducing the possibility of the blade shifting during
sharpening (see Figure 4).
Hint: The blade can also be positioned by putting two pennies (one
at each end) under the front of the jointer blade sharpener as it rests
on a fl at surface. Let the bevel of the blade slide down to rest on the
surface, then tighten the thumbnuts.
