I use my jointer to clean up sawn edges
before glue-up. The results are great except
when I try to joint figured wood. Any suggestions?
Jointing highly figured wood often leaves nasty tear-out. It’s times like these that
a tablesaw and a specialized blade called a glue-line rip blade come in handy. A
glue-line rip blade produces a much smoother edge than even the
best 40-tooth combination blade can.
Glue-line rip blades are designed and used differently
than standard rip blades. General-purpose rip blades are
made for fast, rough cuts. Typically, they have 24 flatground
teeth. A typical glue-line rip blade, on the other
hand, has 30 teeth with every other tooth having a
“triple-chip grind.” The triple-chip tooth hogs out most
of the material and the flat tooth cleans up what’s left.
This produces an ultra-smooth cut that’s ready for glue-up.
You set up a glue-line rip blade differently than you do
a typical blade (see photo, left). You’ll get the best results
by feeding the stock at a slow, steady rate.

The glue-line rip blade
should be set so no
more than one-quarter
of the height the tooth is
above the wood.
