What's the problem?
Currently, the Nobelisk requires these ingredients: beacon, black powder and steel pipes. So, to automate the production of Nobelisks you have to build 2 manufacturers (for beacons and boom sticks themselves). In addition, you need to provide sulfur, coal, iron and copper ore (for stock wire recipe). This seems to be quite a high requirement in case you want to make a convenient explosives/ammo factory.
I propose removing the beacon from the Nobelisk recipe. This will remove the need for copper (required for wires in beacons) and manufacturers (no need to manufacture beacons, and you could use the assembler for Nobelisks). This recipe will allow the player to more easily acquire explosives (thus exponentially increasing the enjoyment), but it still requires the player to find sulfur + coal sources and automate the production, so i think that it is quite balanced
