Love it and not a bad description either. If we worked to standard engineering practises then a 1/4" nut would be tightened to about 80 inch pounds (near enough 7 foot pounds) and a 5/16" nut to about 120 inch pounds (10 foot pounds). That's only a 14 or 20 pound force on the end of a 6" spanner (wrench, if you like).

Most prop drivers are machined from bar stock but the ST prop drivers are cast and hollow inside. They're designed to handle the forces involved but don't allow for the occasional gorilla that buys an ST .
