Should have taken a pic, but I just loaded a piece that looked very similar to the bottom one in this pic of yours. Pretty sure it was Maple. Those first 3 pics are kinda gnarly.
Talk about a slippery slope. woo, someone might ask , "who the hell are you talking about!" Your on your own buddy.
I gotta get a picture of a piece of white pine, full of knots and resin, I put through the splitter at least five times and still couldn't get the pieces apart without a sharp hatchet. I got disgusted with it and tossed it aside, couldn't see fit to put it on the stack for "normal" firewood.
Looks like what I have been dealing with. It is all heat the hard part is finding a good way to let it season without messing up the pretty stacks. Thanks for sharing!
Dave, if you were a good artist, I'd bet you could make some really neat things putting some of those together in different ways!
