As a young twenty something, I sat in the “saw box” with Wally Purcell, a veteran sawmill manager, who explained to me the way to cut this monster 3 1/2 foot diameter log to get the highest grade value. It was 1980, and I had just been hired to be the salesman for a world class sawmill in Estacada, Oregon owned by Crown Zellerbach. For years, this mill cut big Douglas Fir logs from the Mt. Hood National Forest. The mill known as Estacada Lumber was one of the best quality, 40 foot cutting mills in world, shipping its products all over North America, Australia, Japan, and Europe.
