Hey All, thanks for the welcome back.......
Appreciate all the input to the question. Yesterday, the fella that gave me the Porta power and lift cylinder, said he needs me to come down and he's got a vent for the upper cylinder, that will make the double action cylinder act like a single action. Super cool, huh? Mr. Oztules, thank you for the right on answer. And, thanks to all (Wooferhound, TomW, Wolvenar) for your inputs, too!
I'm gonna rebuild the pump and the cylinder before I build the mount for the tower. But I'll keep you all posted as I go (good or bad). Like I said, I've never played with hydralics before so this is a learning process.
Take care all and thanks for the warm welcome back.....
Bill
