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,

///Low volume for water jet operation but ample volume for an explosion. I see alot of posters dabbling with the idea of a water jet. I hope everyone realizes the dangers of dealing with such high pressures. A tiny stream of water without abrasive even at 10,000 psi is enough to cleanly take off a hand. and that could happen as easily as a hose rupturing. The pressures required for water jetting are nothing to play around with. Especially when we talk about containing them in a large vessel such as an old modified hydraulic cylinder. I'm not trying to thwart anyones enthusiasm. Just be careful and aware of the potentials of the design.

A few weeks back I had the notion of building a CNC laser. Until I researched it and discovered how dangerous it can be. The lightbeam which is invisible could be reflected off of a workpiece and blind someone or myself permanently. No thanks. Not to mention the initial expense of a tube powerful enough to cut even thin steel. For metalcutting in a gantry type machine in the homeshop, for safety's sake we are limited to plasma or acet/oxy torch. Although, if someone achieves a homemade water jet capable of cutting steel and after 6 months they still have enough fingers to type with, I'd love to hear about it. :-)

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.
