With some Edison content at 15:00 here is an interesting discussion into the origins of screw threads. The self locking nature of worm screw threads is discussed. The clever spiral drive adaptation that Victor used is not mentioned. Overall, a very good presentation, almost as good as one of Shawn’s!
