Executive summary
Background
The NZDFI aims to establish a ground-durable eucalypt resource under a short rotation regime to produce pole wood for use as agricultural posts (Millen et al., 2020; Millen et al., 2019). While manufacturing of round wooden posts is a mature technology for which machinery of various capacity and different technical solutions exist, their suitability to process the NZDFI species is unknown.
More details on wooden post manufacturing (Altaner, 2020) and experience of durable eucalypts used as agricultural posts (Lambert and Severino, 2018; Millen and Altaner, 2017; Millen et al., 2018) can be found elsewhere.
Objective
The objective of this work was to test the feasibility of manufacturing posts from NZDFI species with existing post manufacturing machinery. The work focused on the question of whether the thick and fibrous bark of the durable eucalypt poses a challenge for the post manufacturing machinery. It was not intended to produce an elaborate data set enabling robust statistical analysis but rather observe the post production process with the NZDFI species to a) give confidence that round posts can be produced from NZDFI species and b) identify potential problems guiding the development of technical solutions. A by-product of the trial were the availability of a small number of posts for further study and demonstration purposes.
