Cleaning out my old tin shed (getting a new tuff shed) I came across a hydraulic jack from an engine hoist. I forgot I even had it, it goes to show you that you should clean your shed up every 15 years whether it needs it or not! My next door neighbor actually gave it to me a long time ago as he was moving. Anyway, I think it works, I can take a picture of it if you are interested. I have no need for it and its yours if you can use it.
