Re: Mysterious Screw
Gee... I can't believe all these teams that let the students play with their leadscrews and IGUS e-chain track... I thought those were to keep the mentors busy!
I also can't believe that no one has mentioned the coolest part about the leadscrews... you will note that they are quad-start (look at the end of the screw and you'll see four "bumps"). That means that there are actually four seperate "threads" twisted around the axis of the screw as opposed to just one for a standard "single start" bolt or screw. That is why the nut moves so quickly. It moves so smoothly because it is magic. Jason
