Newbie,meet Newbie.I just signed on recently.----------I bought my first wood furnace in 1993 and used a vertical log splitter for several years.If you don't know about TimberWolf log splitters,Google them and look at what they offer.They show a splitter that splits 10' logs on their display page.
I have a Timber Wolf splitter that is 4 or 5 years old (TW2-HD) and I am crazy over it.You can see it in their display.I bought this splitter with a 4" cylinder as a HD 20 ton splitter.After using it awhile I found myself getting chunks stuck on the wedge and had to beat them off with a 30# sledge all too frequently.That aroused my curiosity and I began doing some math using several pressure numbers off the top of my head.I discovered that a 4" cylinder took a tremendous amount of pressure to develop a 20 ton splitting pressure.Much more than possible with this pump.When I contacted the company,they sent me a pressure gauge and told me to check the setting of the relief valve and raise it if necessary.It was set where it was supposed to be.Long story short,the 20 ton splitter was putting out a little over 13 tons force.They sent me a 5" cylinder,I installed it and it worked great.They never did pay me for my aggravation but at least they guided me toward solving the problem.I still see this splitter listed as 20 tons splitting force with a 4" cylinder.Apparently they don't fear lawsuits.----------shorman
