Mysterious Screw

The function of that part is to keep one student occupied playing with it during the entire build season. It doesn't have to be the same student all the time, they can take turns.

i have one of those on my hobie cat, i have no idea what it does though, so i leave it alone

Can't you connect one directly to a motor and use it to open and close claws and mechanisms of that sort?

Actually, the primary operators of this device should be those who cannot land the lead position for "Time Waster", whose sole purpose is to use the Igus track throughout the entire season.

Team 79 used one this year to raise and lower our scissorlift.

[Lowfategg]

An awesome device used like crazy on all sorts of machining tools and other great things.

Lead screws FTW!

Sweet guys! Thanks for the info.

i know that team 103 has used them last year on their robot, to raise a section of their robot up to knock off the track ball.

Hmm, your team is organized different then mine... I always thought the head time-waster got the screw, and the assistant was stuck with the track... especially considering we actually used the track this year!

you will find lead screws and ball screws in machines such as lathes and mills.
they are both do there job very well as for which is better it depends on what you are doing i have been told that for mills and lathes if set up right ball screw tend to be more accurate but u can get real accurate lead screws as well.

Lead screws can be made exceptionally accurate. Moore Tool developed jig boring machines that are very accurate and they used lead screws. Richard Moore has been recognized as the man who "gave the world’s industry an additional decimal place of accuracy!"

His son Wayne wrote the book "Foundations of Mechanical Accuracy".

I don't know what they use these days, but they have jig grinders that will position within 90 millionths of an inch in 18 inches of travel.

From what I hear, on team 829 the Head Time-Waster becomes the Lead Button-Maker.

Because after a day of cutting out circles with scissors your hands are so cramped up you cant operate the lead screw anymore.
