Re: Great Dane excavating co.
Cooper your drawing of the cylinder shows a lower and an upper port why? If you are going for a telescoping cylinder you only need one port. As for your cylinders you don't need a hole on the stage bottom you just need the tube and the seals to keep the oil in the cylinders. Your picture shows a bleeder on the top stage and that is good but not really need for what you are going to do. You will need o rings to seal the stages and to be guides. Hope I have helped it has always been my intentions to build a multi stage cylinder but that is as far as I got. Ed
