Commercial Evaluation of SDR (Saw-Dry-Rip)–Using Aspen for Door Parts
Manufacturers of aspen door parts (stiles and rails) use lumber from grade-sawn aspen logs, dried at temperatures less than 180?F. This practice results in a great deal of material that […]

Comparison of stiffness and frequency characteristics of a Hi-Earn, Detenso, and standard sawblade
Two developments in circular saw design aimed at improving performance are the Detenso and the Hi-Earn saws. Undocumented claims by saw suppliers and sawmillers state that these saws reduce kerf, […]

Compression Slicing of Wood
The compression slicing technique is an alternative to ripsawing for producing thick lumber from cants. Lateral pressure, not exceeding the wood’s proportional limit, is maintained while a sharp-edged blade is […]

Control of Veneer Thickness During Rotary Cutting
A major cause of thickness variation of rotary-cut veneer is a reversal of the forces between the knife carriage and the wood, depending on whether or not the pressure bar […]

Cross-Grain Knife Planing Hard Maple Produces High-Quality Surfaces and Flakes
Hard maple panels of short, clear cuttings were aligned parallel and perpendicular to the feed direction so the material could be knife-planed parallel to and across the grain. The panels […]

Crosslinking Affects Sanding Properties of Wood-Plastic
Heat generated in sanding wood-plastic combinations (WPC) causes clogging of the abrasive by the thermoplastic resin. By adding 1 percent of a crosslinking agent such as l,3- butylene dimethacrylate or […]

Crushing Strength and Modulus of Elasticity of Unmachined Lodgepole Pine Stem Sections Compared to Machined Dowels of the Same Diameter–Kerfed and Kerf-Free, Round and Half-Round
Six-inch-long cylindrical or half-cylindrical stem sections from suppressed stands in two western Montana locations, tested when dry in compression, showed that specific gravity and two mechanical properties–maximum crushing strength parallel […]

Cryogenic treatment of tungsten carbide reduces tool wear when machining medium density fiberboard
A cryogenic treatment (-306?F)was applied to C2 tungsten carbide (WC -6% Co) and compared with untreated carbide to determine if tool wear could be reduced during turning tests with medium […]
