Book excerpt: This paper describes increment cores (a useful tool in forestry and wood technology) and their uses which include age determination, growth increment, specific gravity determination, fiber length measurements, fibril angle measurements, cell measurements, and pathological investigations. Also described is the use and care of the increment borer which is essential in obtaining good cores. A caution is also given as to the tree damage that boring can cause, with suggestions for minimizing damage.

Book excerpt: In some areas, harvesting mixed hardwood species may be necessary to provide enough log volume to keep a hardwood stud mill in business. Basswood and red maple should make good studs and should be suitable for combination with yellow-poplar, paper birch, or other species shown to be good performers using the Saw-Dry-Rip (SDR) process. This study evaluates basswood, red maple, and black willow for making studs using SDR. Results show that basswood and red maple have lower crook when SDR is used with either conventional or high-temperature drying. Black willow crook is lower using SDR but is still much higher than basswood or maple. This poorer performance is believed to be due to wetwood and poor drying. Wrap in wetwood studs is due to wet pockets that are exposed when ripped from the flitches, causing delayed shrinkage after ripping. The percentage of pieces rejected because of warp, based on the STUD grade, is 50-100 percent lower for SDR than for conventionally sawed studs.

Book excerpt: Data show that the saw-dry-rip (SDR) method produces higher yields of STUD grade material than is produced by conventional sawing and drying or than has been produced in other studies using young-growth ponderosa pine. The studs are also more stable. Small logs were live sawn into flitches. The flitches were kiln-dried and then ripped into studs for planing. The SDR treatment with high temperature drying resulted in 77.8 percent of studs so produced meeting the STUD grade after 30 or more days of storage. Juvenile wood, compression wood, and less than optimum drying are discussed relative to problems yet remaining in the manufacture of studs from small ponderosa pine logs. (Author).
