What it concludes

Wood tools can successfully form sheet metal without being damaged if the right shape and clamping are used.
Pressure-treated 4x4s do not machine well in a CNC machine with a roughing end mill.
Plasma cutters provide clean cuts for sheet metal clamping plates.
Compound bends in sheet metal exhibit severe springback that requires over-bending in the tool design.
A 16-gauge sheet metal is the optimal size for this forming process compared to thicker options.
