      A total of logs from two species, red oak (Quercus rubra) and yellow poplar (Liriodendron tulip(/era), were measured in five typical hardwood sawmills across West Virginia to evaluate log sawing practices and lumber recovery. Log characteristics such as length, diameter, sweep, taper, and ellipticality were measured in sawmills, while log.

The drawback to this method is that it creates a stack of narrow boards (drawing 1). Instead, I use a method referred to as sawing “through-and-through” (drawing 2).

In smaller mills this is the only saw that makes boards from the log. A log having a single high-grade face is placed with this face against the knees. At mills turning down, a 90 turn is used for successive faces (fig.
