I've successfully tested the second version of a high pressure hydraulic pump. I'd like to make it open source.But having some trouble getting the design simple enough that it can be made with a drill press. There aren't any projects that I've seen coupling Arduino with high pressure hydraulics...I'm wondering if anybody is even interested in building their own stepped motor driven hydraulic pump?

I can't see how your pump works but I'm interested to know why you decided to use a stepper motor to power it. Wouldn't a DC motor be cheaper and more efficient, or are you making use of the precise positioning capability of the stepper motor somehow?
Precise positioning capability of the end component (without feedback) will probably depend on the pump design. Getting linear pressure control from just the pump could be an issue.
