I have been building small hydraulic forging presses. I run a 5hp motor and a 16gallon per min two stage pump. The forging press moves pretty fast, what I want to do is make a self contained hydraulic hammer sort of like an air hammer. I am thinking about using a 30 gallon per minute pump with the 5hp motor but keep the pressure around 200 psi. I should see ram speeds of around 15inches per second on a 3 inch cylinder. I will set up the valving to allow the cylinder to cycle like a power hammer. The low pressure should keep the HP needs very modest and wear and tear on the system tollerable. I just made a 4 inch cylinder with a 14 inch stroke, I put 1.5 inch ports on it they are huge so that oil flows very freely. Anyone ever seen anything like this I have seen giant hammers but never small ones, I am thinking 50-100 lbs ram and 200 blows per minute probably less but a guy can dream.
