Hi Stewart,
If you want retro there is an Australian guy who produces videos on YouTube (I know – more technology but it's not all bad) At the moment he is producing a series on his building a version of the Antikythera machine (ancient Greek mechanical computer) and is doing it using tools and methods that he believes may have been used by those ancients.
He has even made his own files from case hardened mild steel and uses these to cut the gear wheels. His videos include ones which explain how he believes those Greeks adapted their methods and tools in making the machine. Well worth watching.
He goes by the name 'Clickspring'. Just search on Youtube for him and 'Antikythera machine. These videos are also very well produced and are as polished as his excellent craftsmanship which I can only dream of achieving. His videos on making a skeleton clock are also excellent.
His video on making hand files is here:
