Device for measuring timber degradation with handle and angled timber engaging portion, with amount of rotational spring back indicative of degradation

摘要

Handle 11 is connected to shaft 8, the axis of which is typically offset from that of containing tubular body 7 which is held stationary via holding plate 6, and located within a drilled aperture 4 of the timber. The handle is turned and the amount of spring back is measured to indicate the extent of timber degradation.
