My hydraulic splitter has a wedge angle of 10 degrees. It will shear cross grain with no problem. I can literaly cut wood across the grain. However, when I split a log, the ram must push the log almost entirely through to the wedge before it comes apart. Since my six inch ram has plenty of power, I am thinking that a wider angle wedge, maybe 30 degrees or so would cause the logs to pop apart sooner. Anyone willing to help by measuring their splitter wedge angle? I think I will leave the original wedge in place and build a slip on four way, but I want some better angle knowledge before I make it. Thankyou.
