Trip Hammer

It is a model for a big and working trip hammer and because of its measures you need to turn the mill slowly by your hand for understanding the mechanism. Tap water could be less or more powerful than you need. You can see that it requires calculations for different measures, for different turning speeds and strength of the water stream.

"A trip hammer, also known as a tilt hammer or helve hammer, is a massive powered hammer. Traditional uses of trip hammers include pounding, decorticating and polishing of grain in agriculture. In mining, trip hammers were used for crushing metal ores into small pieces, although a stamp mill was more usual for this. In finery forges they were used for drawing out blooms made from wrought iron into more workable bar iron. They were also used for fabricating various articles of wrought iron, latten (an early form of brass), steel and other metals." (Wiki)
