I have a log splitter i built that works really well and will split about anything. It doesnt flip vertically though. I see people building a lift with hydraulics and different valves. What is comes down to is i cant afford to by another valve and cylinder right now. I was wondering if a 12v scissor jack with 2500lbs capacity might do the trick. I have all kinds of scrap steel and welders, so i can make it fit. I just dont know how much force you would really need to lift a decent log. I wont be lifting anything 48" in dia. Any advice on alternatives would be appreciated. Thanks
