building a cnc waterjet?

[fastolds]

I would like to build a cnc waterjet but who makes good plans for these? If I do it I don't want some piece of junk.

Every few months I see people talk about the feasability of building one, but I've yet to see anyone actually build one. The 25K-50K PSI is usually the issue.

It's no different than any other three axis motion platform except the cutting device is a bit more expensive and your table would have a collection tray below. Shielding your motion components from moisture is a big design consideration. I think the main reason you don't run into a lot of home brewed water jet machines is the cost of the pump, head(s) and controls for the high pressure water, as Gerry eluded to.
