Here is another one joining the crowd and making a press. I am trying to decide whether to build my press onto the rear of my Kinyon style power hammer or to use an H frame I have. My hammer uses an 8 X 8 X 3/8 wall tube for its frame so it should take the pressure really well without deflection. My pump is two stage, 13 GPM. Which way would you go guys? H or built off a vertical post?
