Re: Mysterious Screw
Large versions of this little screw are used to adjust position on satellite dishes all over the world. I work with one dish that has a lead screw for elevation and it is connected to a 3/4 HP motor with an electric brake. The screw is about 4' long and at least 2" in diameter. Another dish that is much larger has two, one for azimuth and one for elevation. Both can be operated by a hand crank or electric drill attachment. The dish is 6 meters in diameter.
