Most youtube videos about making a blacksmith anvil from a piece of rail (railroad, crane, trolley car, etc.) don't show how to make the hardy hole, so I made a video on that subject. Note: In the filing sequences it sounds as though the file is just skating, but it is really cutting quite well. It's the microphone in the video camera, I guess, that makes it sound that way.

Excellent video! Very informative and great production.
Re: metalworking. You had to resharpen drill bits a lot. Would carbide tipped bits work? You also had to do a lot of filing. I use a carbide rasp bit in my die grinder that might be good for roughing. E.g.:
