I was playing around on a log splitter speed calculator I found online. I filled in all the fields with different size cylinders and pumps just to get some ideas. One of the calculations was a 3 1/2 inch cylinder with a 20 inch stroke and paired with a 22 gpm pump.The cycle time was 4 seconds. I know that sounds ridiculous, but I started thinking. Is such a thing even possible or would the internals of the cylinder self distrucked under that kind of speed. I don't know anything about hydraulics. but I figured you guys could answer my question. Thanks.
