slot to remove all the pitch or sawdust. Coat
the knife and gib with a metal protectant
(refer to
page 32), then fit the gib back into
the cutterhead with the knife.
9. Make sure the beveled side of the knife
is against the cutterhead, as shown in
Figure 61.
10. position the straightedge on the outfeed
table and over one end of the knife, then
use magnets or an assistant to make sure
the straightedge stays in full contact with the
outfeed table along its full length.
11. insert the 3mm hex wrench through the
access holes in the cutterhead, then rotate
the jack screws to raise or lower the knife (see
Figure 62). When the knife is set correctly, it
will just touch the bottom of the straightedge
without lifting it.
