The thickness planer
has a rotating cylindrical
cutting head that
has 2-3 dual sided
removable blades. The
blades rotate at a high
RPM and shave off
layers to flatten the
sides and cut the
lumber down to the
desired thickness.
The motor not only
drives the blades but
also the feed rollers,
usually at 16-26 feet
per minute. The in-feed
roller has ribs to pull
the lumber into the
planer and the
out-feed is often
smooth in order to no
leave imprints on the
finished board. The
blade head moves up
and down to adjust to
the desired thickness.
Sam passes the
stringers through the
machine until all of
them are the same size
and let’s lays them together
until he is happy
with a composition of
the aesthetics of the
finished wood. This
machines drastically
helps the boys improve
the look of the timber
they receive and use.
