Yes, an auto jack COULD be made to split wood, but it wood be s-l-o-w. But if you only have that one or two gnarly pieces.....
I use a maul, a monster maul and a sledge with wedges. Elm is the most tenacious, twisty, fibrous wood that I have come across in my woodlot.
I am tempted to rent a log splitter to do just all elm, because some days it is just beyond my ability.
The Smart Splitter looks like it wouldn't make much more than a dent in my elm.
They are all standing dead wood. An old timer told me that elm is hardest to split green, to wait a year and then it will split more easily. So far this hasn't been my experience.
I have made the cuts with the chainsaw on top for the splits to use wedges and sledge, but elm is still aggravating with this technique.
I'd like to hoist a heavy wedge with chains above the log and let it drop.
I wonder how high it would need to be to gain the drive power of a gas powered splitter?
