Water-powered trip hammer video

Featured Replies

From YouTuber Lindybeige, whose videos about ancient military history are also quite good. 

(Thanks to Daswulf for reminding me about this.)

Really fun history and to see the old hammers and buildings. 

Amazing that they kept the Gravity turned on at all times!  I was impressed that they included Abraham Darby, Benjamin Huntsman and Henry Bessemer---people we should all know about!

I do wish they had discussed how shear steel was made and how the transition to crucible steel went.

Excellent video!  Thanks for posting.
