and to assure that they get the volume
they need on time.
A close connection with the supplier also assures a reasonable return
policy for incorrect material and
supplies in a tight market. Note: Some
wholesale lumber suppliers do have
staff that works closely with buyers, especially medium and small purchasers,
but this is not always the case.
As I said at the Wood Pro Expo,
our industry needs to begin working
back into the supply chain for lumber,
perhaps back to the sawmill. And
maybe in the extreme, we will see some
medium sized companies following the
lead of some larger companies, like
Ikea, that are purchasing their own
Short of such land purchases, our
industry will likely find direct contact
with sawmills by a dedicated lumber
buyer representing the manufacturer
of wood products is essential as we
move forward in the next few years.
Indeed, we do export lumber, but
oak is the largest volume. Overall, we
import 10 percent of our hardwood
lumber needs. But, the big issue
increasing hardwood lumber prices
will be supplies, because of a lack of
Higher lumber prices mean that
the yield of parts for lumber will be
extremely critical for a profitable
operation. I will be giving practical
tips about improving yield at Wood Pro
Expo educational seminars in Wood
Pro Expo Lancaster this fall.
QWe have received some complaints about small cracks (I believe you call
them checks) in the red
oak stiles and rails of our kitchen
cabinet doors. We replaced the doors
a few months ago and have no more
complaints, but what should we do to
avoid this costly issue in the future?
AChecks or cracks that open up in the finished product are the result of shrinkage of the wood after finishing.
However, dry oak is very strong…so
strong that it is virtually impossible to
have enough shrinkage force that will
initiate a new check or crack, even if
the moisture loss that causes shrinkage
is 3 or 4 percent MC.
Stated another way: It would be very
unusual to have lumber that is so wet
(always check the MC of incoming lumber) and air in a home or office that is
so dry (measure the RH) that the moisture change would be large enough to
crack the strong oak wood. Plus, the
stiles and rails of a door are normally
quite narrow, so the overall shrinkage
is very small, so the force, even with a
large MC change, is small.
So, what you are seeing are preexisting checks; the checks were created at
very high MCs when the lumber was air
drying or predrying. In the manufacturing process in your plant, it is often
difficult to see these checks as they will
be tightly closed (but not healed).
The only cure is to prevent the

of quality in that grade.”
