A materials cut list is useful. I have transitioned a lot in terms of thoughts on how to model efficient workshops and production processes. I no longer have a physical workshop. In fact I have no carpentry skills considering I work with wood a lot. My favorite tool is a brain and the only other tool one really needs is a computer – in these days of cnc cutters, laser cutters, waterjet cutters, 3-d printers, tech shops, hacker spaces etc. Whichever are your favorite tools, just remember precision is more important than accuracy for the construction process of a smart aquaponics garden.
