Tally     The thickness, width, and length piece count of lumber shipped on a particular order.     Back to top       Tare Weight     Tare weight is the weight of tractor-trailer with no load. A tractor trailer typically weigh 30,000 to 35,000 pounds leaving a legal load weight of 45,000 to 50,000 (22 to 25 ton). The heavier overweight loads not only pay the trucker more, but are also more wear and tear on trucking equipment. Back to top         Thinning     The process of removing excess and poorer quality trees from a stand to allow the remaining trees adequate sunlight, nutrients and moisture and to grow at an even rate which improves stand value. Trees that remain when surrounding trees are removed in thinnings or partial cuttings respond to this more open environment by stimulated crown development and the formation of wider growth rings along the bole. Effects upon growth are often dramatic. The effect on density of wood formed thereafter is largely unpredictable. However, the timing of thinnings has much to do with the effect upon wood quality and thus should be considered when developing a management plan.     Back to top       Thousand Board Feet (MBF)     One board foot is wood that measures 1" x 12" x 12". Logs and lumber are measured by MBF or thousand board feet. MBF is determined by one of three major scaling rules: Scribner, Doyle, or International Rule. The board feet scaled for logs is an estimate only. The actual board feet yield depends on how the sawmill cuts the log. It is possible for a log to produce more board feet than was estimated producing an overrun.     Back to top       Timbers     Lumber 5" or more in thickness. Back to top     Trimmer     Square-edged boards must pass in a transverse or sideways direction through a battery of saws that precisely end-trim (PET) the lumber to prescribed lengths Back to top     Twist     A defect referring to a deviation, flatwise, in a piece of lumber, creating the form of a curl or a spiral.
