Hi Folks,

I haven't been around much for fabrication of the frame and probably won't be there on saturday build days at least until mid june, but I would like to help with the implementation of the hydraulics system.  All the designs I've seen are centered around the powercube which is powered by a briggs and stratton engine.  For simplicity and flexibility, I propose using an electric pump either 12VDC or 120VAC, or a standard mount and coupler so we could swap them out.  It could still be powered by a generator for remote applications, or ideally from solar/batteries.  I just see the OSE powercube as being a little more complex than we might prefer moving forward, and we can still get the same force even if we go to a lower power pump, the machine would just operate more slowly.

valve example (just a cheap one...not researched)

does anyone know the force/pressure we need for the rams?

Cheers,
