Wow. We use flanges like that here. I wonder how many of ours were actually made that way....
wow... it's mesmerizing to watch. Obviously this team has built a bunch of these. It's remarkable the steel remained hot enough to be formed over the 13 minutes.
Did you catch the use of calipers at the very end, measuring outside diameter?
It would be interesting to compare this process to what occurs in a modern mechanized steelworks plant.

Brings back good memories for me, I was 20 when I hired on at the Southern Pacific RR. Being a Boilermaker/ Blacksmith using the Hammer was a thrill to work with, we made everything from snow plows to gears for turntables for bridges. We had to get permission from the court house in Sacramento because we shook the building downtown... good times

Just wondering why these wouldn't be cast instead of pounded? Anyone know?
forging is stronger?

I used a power hammer like that to make my outhouse, becoming the first on my block to forge a head...

Forging is much stronger, yes. A casting is like styrofoam compared with a forging.

Exactly. Think of crankshafts or connecting rods in racing engines vs. your common Chevy Vega engine. All the HiPo engine parts are forged
From Wikipedia: Forging can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, its internal grain deforms to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a piece with improved strength characteristics.
