Hi,

I am also trying to make a robot using Hydraulics.

I think I am somewhat behind the curve on the need to know slope though...

I fI buy a hydraulic pump what do I need for the valve/switch thingy? How easy is it to connect one part to another and where do I go for those bits????

And then how do you show that it has been tested to 120% of the opperating pressure?

P.S. And how do you get the cost of it past the wife.....
