I do a lot of hardwood splitting by hand. Lots of good advice here. I'll echo those and add a couple:
- Search for existing cracks/weaknesses
- Hit more towards the outside vs dead center on big pieces
- Try to hit the exact ame spot multiple times. Accuracy takes practice keep trying! Its very satisfying once you get it.
- Keep the round lower. Don't put it up on a tall chopping block. The lower it is the more time you have to build force on the downswing.
- Build up your confidence/technique with the maul so you can really let loose and smash. I sometimes even yell or jump a bit for that extra umph. Especially if beer is involved lol.
- Sometimes the wood will simply laugh at you and the maul will bounce off like it's hitting a rubber ball. Stumps are a good example. Don't kill yourself and turn the round/your body into hamburger just set it aside and noodle it with the chainsaw. Live to split another day.
- Be aware of knots. Put them on the bottom when swinging, you arent gonna swing through one. It can feel like hitting steel and be painful. If its too knotty noodle it toss it. Not worth an injury.
- Switch to the lighter axe after the first break or two once its a manageable size. You'll be able to go a lot longer using the smaller axe.
- Learn your species of wood. Red oak splits like butter but elm or box elder will give you a heart attack. I can split a 36" red oak round in one swing but be unable to split a 16" box elder round in 20 swings. Save the tough ones for the splitter day.
- Buy one or borrow/rent a splitter for a day. Hand splitting is one of my favorite things to do but doing 3-5 cords a year adds up physically and it's time consuming. Even if you get a splitter you can still save a cord or however much for enjoyment/exercise but at the same time save your body in the long run.
Here are some big boy rounds I've split this week with my maul. Red oak, cherry, red maple. The oak took 1 swing and the cherry/maple 3 or 4.
