The "Iron, How Did They Make It" collections from Bret Devereaux ( https://acoup.blog/2020/09/18/collections-iron-how-did-they-make-it-part-i-mining/ https://acoup.blog/2020/09/18/collections-iron-how-did-they-... ) describe the complete process of making iron tool (you want to make some steel: for that you need some iron; for that you need to melt it; for that you need heat; for that you need coal; for that you wood) in a medieval setting. Otherwise I enjoy the Primitive Technology YouTube channel ( https://www.youtube.com/@primitivetechnology9550 https://www.youtube.com/@primitivetechnology9550 ). John Plant makes stuff strictly and entirely from scratch. It really shows how difficult it is to start civilization.The distinct lack of spoken narration and typical YouTube overstimulation is refreshing (it's closer to the ASMR style of channel in that regard).
