That's about the same setup as I have been looking at and that's what I'm getting ready to dive into, BUT, if this isn't a good idea, let me know. My stand will be about the same, I'm going to get a Prince Cylinder from Northern Tool, along with a manual Porta Power Pump since the cash outlay for a totally powered system is impossible at this time. The one last question I have and forgot to ask my expert was the fittings between the pump and the cylinder are different, but I'm sure I can get some adapters to make everything fit. Would I need to worry about a loss of power? Here are descirptions of the cylinder and the pump. I may go with a different cylinder, but this is close to what I'm looking at.
