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.

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.:

(that one is very expensive - I got mine years ago on eBay as a lot of
10 for about $1 each).

I bet if he had used flood coolant, far less resharpening would have
been required.

Or just taken pecks no more than a drill diameter before re-lubing. I saw
him cut more than an inch in dry metal more than twice. I also saw him
pause in the drilling (just one or two times), which kills the hell out of
bits and work-hardens the surface.
