The large circular saw that does the work is guided by a laser. Cut boards are piled and covered with plastic sheeting to air dry. A 20 x 36-foot wall of solar panels heats their kiln. Up to 50,000 board feet of lumber can be dried in the kiln at one time. Depending on the weather, drying time can be only but a few weeks.
Fans push air down and through the unstrapped lumber piles to slowly remove moisture.
Daily cycles of warming and cooling release stress that could produce twisting and curling. The result is straight, high-grade lumber from trees normally destined for firewood. For trees to use in constructing log buildings, the Hallands look for standing spruce forest that has been killed recently by forest fire. They shrink the least, and settle the best. We'll go 100 miles to get them, sometimes.
