Aidan Williamson/Metal Fabrication Certificate
Contents
Introduction
Purpose
This page will be where I can try a wiki-embedded attempt to achieve the OSE Metal Fabrication Certificate remotely. Remote achievement of this certificate does not have to be absolute - it could be a precursor to an on-site exam. I recommend this for experienced first timers at Factor E Farm looking to demonstrate their existing competence and avoid unnecessary training.
Completion of this page will happen over time, as photos/videos arise.
