Hi,
could you maybe provide a feature like in this mod?

I am pretty sure that the only thing you would need to do, @raoulvdberge is add ProjectE as a library, then add support for the solderer, because that is the only new crafting type that is added. I think that the way it works, is it checks things like ore spawn rates, and such, adds a value, and basically combines that when crafting, or smelting, or similar methods. NOTE: I THINK this is how this works...

That seems like something either Project E or EE should implement. Or an addon mod.
