Log Rivening

• arclein

This problem of modern productivity has been an open question for me for decades. It turns out that any log passing through our cutting system does several things; 1] Half the material ends up in the chipper 2] Real strength is variable, as is warping and twisting. All adds additional post manufacturing losses. For this reason boards are generally used only as cladding or for short length reinforcement. Even robust two by fours are uneven in strength and must be watched. 3] The heartwood or outer shell is completely wasted in all but the largest logs while we fully utilize the weakest wood in the core. What heartwood that is preserved is also ill positioned in the plank for providing more strength and general integrity.
