This is a 100 lb Hackney power hammer dated 1888. I use this hammer for shaping the iron while it is hot, along with my other two hammers and my press. This machine offers exceptional control. It is a pneumatic hammer with variable speed and a brake acting directly on the ram. This brake allows the ram to be stopped quickly, and it also allows a very positive hold aginst the work. It has over 30" of ram guidance, a solid anvil and a hollow standard with the control links contained inside. It is the Rolls Royce of all power hammers. Unfortunately, the company went out of business in 1894, and this is the only working Hackney known to exist.
