I think that guy has done this once or twice before,... really liked that "monkey killing wrench" at the 1min mark. Everybody has one of those single-purpose wrenches in their garage.
Mine is about 4' long to fit a 54mm nut torqued to 365lb/ft, which is the Jesus Nut on a 13b rotary engine eccentric shaft that holds the entire rotating assembly together. Single purpose, other than bragging rights...
