Abstract

Potential of two processing methods to reduce sweetgum and sassafras lumber defects.

Abstract

Sassafras (Sassafras albidum) and sweetgum (Liquidambar styraciflua) logs from Louisiana were grade sawn and the lumber milled to 4/4 thickness and processed according to two methods. One half of the boards of both species were ripped prior to drying and the other half were dried prior to being ripped to the desired dimension. A statistical analysis revealed that the non-conventional method gave a significantly greater twist, crook, and crook per foot than the conventionally processed boards for both species. Sassafras boards produced with the non-conventional method had significantly higher bow and bow per foot than conventionally processed boards. It is emphasised that the non-conventional method did not follow the Saw-Dry-Rip (SDR) methodology.
