Splitting wood rightly


When we first moved into a house with a wood-burning fire, I needed to get and prepare the wood, but knew only what I had seen in movies. Through reading and consulting neighbours, I learned the basics of felling trees – either invasive species on our property, or wood that could be coppiced or pollarded and would grow back – and then to dry the logs and saw them into blocks. Finally, I tried chopping the wood the way I’d seen people do it on television, taking an axe and swinging it down full force, but it took a lot of work, and the thin blade often got stuck. Pulling it out seemed like getting Excalibur out of the anvil, and most of my attempts yielded slapstick results that I’m glad were not being filmed.

Eventually, though, an elderly neighbour stopped by and gave me a bit of advice: you don’t chop wood with an axe, as you see in movies. You split wood, with a maul.

The thin, sharp blade of an axe, I discovered, is designed to chop across the wood fibres, as when you’re chopping down a tree. Hitting a tree trunk over and over in the same place cuts the lignin fibres above and below, knocking out chips and creating the familiar V-shaped incision. Axes are also lighter, about two kilograms, as you have to put all your muscle into the swing and don’t have gravity to help you.  

A maul looks similar to an axe, but has a longer handle and a wider, heavier metal blade – wider so it doesn’t get stuck, and heavier so it comes down with more force. A maul’s wide, blunt blade is made to cut in the same direction as wood fibres, as when splitting logs for firewood; trying to cut down a tree with a maul is about as effective as doing so with a sledgehammer. Mauls usually weigh about four kilograms to carry more momentum in the swing; you’re swinging in the direction of gravity, so the weight becomes an advantage and not a liability.

Once you realise their purposes, their handles also make sense. An axe’s handle is great for swinging sideways, but swing it down and you risk hitting your legs. A maul’s longer handle hits the log with more force than an axe can, and if you miss, you just hit the ground.

To split wood, wear safety goggles if you can, although I’ve worn just my glasses in a pinch. Do wear something, though, as splinters can fly everywhere. Wear gloves that fit and can grip the handle.

Take a log of about 20-to-50 centimetres long – any longer than that and you want to cut it again with a saw before you try to split it. Check for knots – you can have some, but position the log so your blows avoid them as much as possible. If it already has small cracks, try to cut in the direction of those.

Put the wood you want to split onto a stump, or onto the ground – but not onto stone or pavement, lest you miss and get shards of stone and metal flying everywhere. Stand with your legs apart slightly, with one farther back than the other, like you’re taking a step forward.  If the maul won’t split a stubborn piece of wood, you can get a few wedges, inserting them into the log in the cuts your maul made, and then hitting them with a sledgehammer. 

I wait until my logs are dried before splitting them, but ours are lilandia trees in the pine family – other types of wood, I’m told, are easier to split green. Most woods need to be dried at least six months before they can be burned in the fireplace, and preferably nine. By the way, we only cut our lilandia trees, which were numerous and overgrown on our property and are an invasive species, or woods that we can coppice or pollard and that grow back quickly, like willow. I find that wood seems to split more easily in cold weather, although it might just be in winter that I’m especially motivated to get it cut fast.

In any case, splitting wood this way on cold days keeps you warm twice; once from the exercise you get, and then in the evenings when you curl up by the fireplace with a good book.
