As an engineering orientated person, that firewood machine is superb.
It makes me laugh that it has a "Danger" sign on it. Like we didnt know.
Having come across the term "cord" related to firewood quite often I looked it up.
A "cord" of firewood is a stack measuring 8 feet x 4 feet x 4 feet. (2.44m x 1.22m x 1.22m)
This equates to 128 cubic feet, or 3.6 cubic meters of wood.
That is a lot of wood.
