I'm a big fan of Clickspring. One really interesting aspect of his Antikythera mechanism videos is that, along with constructing the mechanism itself, he is using the physical details of the recovered artifact to make educated guesses about what sorts of workshop technology were available in the eastern Mediterranean world at that time. Including fairly in-the-weeds stuff like entire videos on what sorts of materials a craftsman of that era might have used to lay out marking lines on workpieces or how one might've soldered two metal pieces together.
