Abstract:

A method was sought and evaluated for making flakes on a ringhead planer modification of a high-speed planer by which flakes would be comparable to those made on a disk flaker about 0.020 by 2 in. by random width. This exploratory method could upgrade the value of the residue from high-speed planers. Matched specimens were cut from typical Construction grade Douglas-fir. Variables were examined Moisture content, angle of knives in ringhead, angle of cutting edge, position of ringhead in relation to centerline of piece being planed, and cutting speed. Attention was also focused on a design that would permit feed rates of up to 1,000 feet per minute.
