Yeah, the wiki is a big help, as is being aware that any item that has ‘Material’ in the list of traits when you mouse over it, can be brought to the guide, when you talk to him one of the options is ‘crafting’, and the empty blue box in that menu can have said items dropped into it for a list of all recipes using it, along with what workstation it takes.
Any sufficiently identical copy of me is me. A copy just means there are more me in the universe.
