I don't know much about the FTB pack, but here is some advice:
- Regular macerator is disabled, there is the automatic macerator to replace it. It's a GT machine which does exactly the same, and more.
- Universal Macerator is not really an early game machine. (like any electricity using machine in GT)
- Actually you are supposed to go through the bronze age, which included machines such as the Small Coal Boiler, the Steam Furnace, Squeezing Extractor and the Sturdy Grinder. Currently, NEI is a bit lacking in that department, but you can macerate Lapis in the Sturdy Grinder and hope for the best.
Whoops, I meant I wanted to craft the automatic macerator instead of universal. And for some reason, I've never heard of the 'bronze age', so I'm reading wiki pages now! But still, thanks!
