I had a bunch of 50" oak to split, and at more than 1000 lb each, these rounds are too heavy to move to the splitter... even vertically. I figured my best approach was to split these rounds into 200 lb chunks with sledge and wedge, so that I could then wiggle them under the splitter. One big crotch, the confluence of two 30" trunks, was the toughest piece of wood I'd ever split. Full blows with the sledge would barely move the wedge 1mm, and when I did finally get it wedged apart (pounding six wedges two-wide each into the gap), it just wouldn't let go. I grabbed my favorite axe-handled maul, stuffed it in the crack, and gave a gentle twist. That's when the handle just twisted off, with surprisingly little effort. This handle is only two years old, and has never seen a bad hit /overshot. Should've used the sledge-handled maul, I guess. I managed to flip the round using my LogRite cant hook, no small feat, and finished from the bottom, with more wedges.
