DescriptionYellow-poplar was dried as 7/4 flitches at high temperatures and subsequently ripped into studs to meet National Grading Rule Standards for STUD grade. The effects of growth stresses in these flitches from smaller logs appear to be minimized by this process. Dry bulb temperatures from 235° to 295° F were explored in five drying trials. Best results were by drying for 28 hours at 235° F, followed by an equalizing period of 48 hours at 200° F and an equilibrium moisture content of 10 percent.
