A simple field apparatus for measuring relative gaff penetration and assessing the effect of additives for improving pole climbability
2000 - IRG/WP 00-20187
A simple apparatus for measuring and comparing the relative "hardness" of utility poles is described. This "slide-hammer" gaff penetration apparatus was designed as a field testing unit to measure the depth of gaff penetration into test poles after application of a uniform and reproducible force to the gaff. The apparatus is simple to use in both the laboratory and field. Data is provided for resu...

An overview of recent studies involving the thermal modification of hardwood species
2019 - IRG/WP 19-40869
This paper outlines recent activities related to the thermal modification of hardwood species, and particularly to tropical hardwood species. Timber demand is ever increasing, but this is being limited by the necessity to protect virgin forest stands. As such, the majority of supply of popular species is being met from juvenile short rotation stands. The limited age from these stands often plays a...
