貌似就是用来制作齿轮的，材料可以自己配置的样子。

@Kharmah
That question isn't that easy to answer. I subscribed and checked (just for you) and you can build the recipe by specifying the needed items from a pre-organized list. the list includes flint, log, boards, rock, cut stone, gold nugget, electrical doodad, blue/red/pruple gem. so far it's the most dynamic gear-crafting-mod I've seen. Thank you very much, Kowalth!

what does it take to craft the gears?

@CrayFish: Hello, CrayFish! For crafting Gears you need by default the Alchemy Engine. It is located in the Science Tab.
