Hey all, I'm looking at doing a water jet/ abrasive jet machine for use on wood and I'm having problems finding pumps that are in the hobby price range. I wouldn't mind building some parts due to the fact that I work in a machine shop but just trying to some basic plans to work off of would be a start. I've thought of using a radial piston pump for hydraulics but there's lubrication (don't know if water would be enough) and then there is how much pressure I could actually get out of it. Piston pump systems typically run around 3000 psi to my knowledge and I'm looking probably closer to 10k psi. I think this would be a great open source project and I'd be willing to try and make some head way but I need somewhere to start from. Any help would be greatly appreciated.
