Thanks Ed.
Well got the other cylinder done and,,,,,, well the presser test was good. I was playing around with the air, extending and retracting. I was just using the air nozzle and have a small brass tube hooked up to it that I can squeeze into the hose. As long as I keep hand tension on it , it stays put. But the trigger on the nozzle isn't too precise and it's all on or all off. Really gets the rod to slam in and out. I was trying to be gentile but I hit the trigger and blew the back right off!!! Well it handled the pressure well but not the sudden impact!!! Was being too lazy to actually hook up the pump and fill with oil!! Well looking back its good and bad. Bad that I have to resolder the back onto the cylinder but good (I guess) that a weak spot showed up now and not later
