How NASA brought the monstrous F-1 “moon rocket” engine back to life

Ars Technica has a great story about NASA engineers "reverse engineering" an F-1 engine so that the plans could be put into modern systems for design and computer modelling purposes. Starting from the outside everything was imaged and in one case a custom torque wrench was recreated. The original work was done in ways that wouldn't be used now and basically resulted in an engine where every one built was unique in some way and built largely by hand. It's a really fascinating story.
