Anyone here handy with a chainsaw? I have a question. I borrowed a nice new chainsaw with a 20" bar to cut up a huge fat limb that fell in my backyard. I've cut it up into 18 inch pieces, but now I want to split them lengthwise into firewood so I can burn them in a brushfire. I've tried a splitting maul, but I just can't seem to split them; my axe just bounces off. So my question is: Is it safe to use a chainsaw for splitting wood lengthwise? With the grain? The owner's manual has hundreds of safety warnings and talks about felling and limbing but it doesn't say anything about splitting.
