and rough lumber is of the highest quality, kiln-dried lumber.
Our lumber is locally harvested (within 60 miles of our mill),
cut, and dried at our mill location in Petoskey, Michigan. All
of the lumber is dried within 7% to 10% moisture content. Ready
to nail or glue, perfect for the professional carpenter or the
Buying By The Board Foot
Until the late 1800's, lumber was sold by the pound. Under
that system, dry boards were less expensive than green wood. So
obviously something had to be done. The system of measurement
that evolved centers around the board foot, a measurement that
covers all the dimensional variables of cabinet-grade lumber,
thickness, width, and length. Today when you purchase this type
of lumber, you buy it by the board foot. To help you estimate
your lumber needs, we have provided you with the formula to
figure board footage below:
A board foot simply is equal
to 144 cubic inches of wood. Think of it as a piece 1 inch thick
and 12 inches square. Board footage is always calculated in
quarters of an inch thickness (starting at no less than 1 inch).
A 5/4 board 6 inches wide and 72 inches long would be figured
like this: 1.25 (thickness) x6 (width) x72 (length) = 540.
Divide 540 by 144 to determine the number of board feet in the
stock. If the board length is stated in feet rather than inches,
use the same method but divide your total by 12 instead of 144.
Hardwood Lumber Grades
Lumber that comes from the outside or the live part of the tree.
Heartwood: Lumber that comes from the inside or dead part of the
White: Lumber sorted for the white sapwood - usually
Hard or Soft Maple.
Unselected: Lumber that has a mix of
heartwood and sapwood.
Brown: Lumber that has been sorted for
heartwood - usually Hard or Soft Maple.
Imported: Lumber that
doesn't grow in the United States.
Domestic: Lumber that
grows in the United States.
Flat Sawn: The grain of the wood
Quarter Sawn: The grain of the wood runs
Select & Better - This is the top furniture
grade. The lumber will range from clear to pieces which will
yield just over 80% clear on the good face. Widths must be 4"
and wider and lengths 6' and longer.
No. 1 Com - This is
the middle grade in hardwoods. It contains more character than
the select & better grade. Each board must be two-thirds or more
usable. For small projects or when a variety of sizes are to be
cut, No. 1 Common is more economical. Widths must be 3" and
wider and lengths 4' and longer.
No. 2 Com - This is the lowest
grade of hardwoods that is normally kiln dried and sold for
furniture and cabinet making. Each board must be one-half or
more usable. Widths must be 3" and wider and lengths 4' and
Walnut & Butternut are typically graded lower than
other hardwoods due to the scarcity of good timber. The widths
and lengths will not be as good and the yield will be less - so
