Gimbal - Wikipedia

The gimbal was first described by the Greek inventor Philo of Byzantium (280–220 BC). Philo described an eight-sided ink pot with an opening on each side, which can be turned so that while any face is on top, a pen can be dipped and inked — yet the ink never runs out through the holes of the other sides.

Antenna Pointing Mechanisms

A common movable element on spacecraft is the communication (or radar/microwave) antenna. Antenna Posinting Mechanisms (APMs) have long been used to perform the vital function of pointing the antenna boresight to its target, and tracking to maintain the RF link to the spacecraft.

Restoration Procedures utilized at Oak Tree Vintage /

Many units manufacturers switched to using control potentiometers that are soldered to the circuit boards and simply stuck through a hole in the face with no "shaft nut" to secure it. Every time you manipulate the control you stress the solder joint. Some fare well, but most do not over just a few years of use. Two terrible designs that are ...
