And im trying to make the overflow misc item chest, basically more chests for more misc storage, and i don't know how to do that. I tried connecting hoppers ontop but they dont transfer over they get sucked into the bottom hopper and stay there.
Not sure what you mean by "bottom hopper", but there is an easy way to expand chests. Just have cascading chests. It requires each additional chest to be lower than the last. But just put a hopper that feeds the upper chest into the lower one. If that doesn't make sense I can post a picture.
