Here's a head scratching one for you... a couple of years ago I saw a video where a person was using a machine of sort to assemble boxes. As I recall, you put the sides and ends in the machine and it squeezed them together and the machine could be rotated (spun) around so the operator could nail one side then rotate (spin) it around to continue nailing the other sides/ends. Anyone know what I'm talking about? No where the video is? Who makes/made it?
