Re: [CAD_CAM_EDM_DRO] Re: water jet

Recently was a discussion re: water jet - as Dave pointed out, X-Y is
not a problem, the problem is a water jet.
In this respect why not to make a pressure cylinder, instead of a high
pressure pump, which could supply necessary pressure of the water jet?
Present hydraulic cylinders can operate up to 10,000 psi, but this
pressure can be increased without hugh cost overruns by increasing wall
thickness and number of seals, number of tie rods. Then the piston can
be driven by several hydraulic cylinders, providing an operation
pressure. An orifice can be located
at the other end of the cylinder. This seems to be not that hard to
implement even at home shop. Just a thought.
