I was playing FTB Ultimate, Single Player Survival, and I decided I wanted gunpowder for TNT (I don't like mining too much...) but I am trying to save supplies until I have a decent amount (I'm trying to be as 'cheap' as possible). I was wondering if this design would work. I used a ton of Cobblestone and some Conveyor Belts. At the bottom is an Item Collector connected to a Chest. I'm not getting too many drops, so I was wondering what's wrong with my design, or if that's as good as it's gonna get with my lack of resources. By the way, the torches are temporary (Just for the shots).
