I want to be able to precisely rotate a item. For this I have positioned the item on top of a very large gear. It is driven by a smaller gear. When the item is in the correct position, I will lock the smaller gear and the item is fixed in the correct position.

How can I achieve a more precise system without making the large gear larger and the small one smaller(without using motors)?

Large gear has item on top of it and is driven by small gear

add intermediate gears, or consider an epicyclic reduction...

Or use a worm and gear, these can do higher ratios compared to gears in a similar volume... see https://www.motioncontroltips.com/worm-gears-what-are-they-and-where-are-they-used/
