I bought the plans years ago from the Appalachian Blacksmith's Association to make my own power hammer. The parts slowly piled up as I found bits and pieces. Finally in July 2010 I stated construction. It was built over 12 days - a month of Sundays plus other days with lots of learning as I went.
I used a "Super Rusty" style, with inspiration from many other hammers on the web, but tried to keep it as simple as possible. Some statistics
- The "anvil" weighs 140kg made from four 75 x 75mm solid bars 800mm long
- The ram weighs 18kg with the dies, made from a 40 x 40mm solid bar
- The initial dies are made from a cut up 10lbs sledge hammer head
- Dies are bolt on and interchangeable
- The leaf springs were "straightened" in my Hydraulic press
- I use a 1hp motor going 1410 RPM
- The pulleys are 2" and 14" which provide just over 200 hits per minute
It was retired in 2014 and rehomed at a forge by the sea. Still thumping strong.
