Power hammers have been in use for hundreds of years at least - the change is almost entirely in the size of the power source (modern engine vs a waterwheel). Power hammers were the reason cams were invented. Whoops: I had conflated trip hammers and power hammers. Power hammers date to the mid 1800s. (Kids this is why you look up citations before you post :) ) |
