There are some old training videos that show how this worked: https://www.youtube.com/watch?v=gwf5mAlI7Ug

Also the Battleship New Jersey YouTube channel has some nice content on this: https://www.youtube.com/watch?v=szxNJydEqOs

See [1] for the basic mechanical components. It's a better scan of the same film the Periscope Film archive sells, which is the first one linked above. No sprocket clatter.

I forget where I saw it (probably YouTube someplace) but the fire control systems (including radar) on the Iowa-class battleships apparently way outperformed their Japanese counterparts. The Japanese has a couple (?) ships with bigger guns/longer range but they couldn't actually take advantage of that longer range to hit big US ships.
