The Tao of Firewood

I hurt my thumb yesterday when I was splitting firewood with an unfamiliar six pound wood-splitting maul. I’m still trying to get the accuracy thing down. The maul glanced off the edge of the log and flew out to the side, twisting my thumb in the process.
I bought the splitting maul for my wife for Christmas. She loved it of course, but since she never splits firewood, she lets me use it. “I’m touched,” she said, “but God wants you to have this.” That was so sweet.
My wife's gift, with it’s relatively lighter head and fiberglass handle, it’s far superior to the 10-pounder I had been using. The reason is because velocity produces much more force than mass does, and this lighter maul can be swung a lot faster (at the sacrifice of accuracy I found out). My smarter brother John, the physicist, is where I go for all my angular momentum needs. “Grasshopper,” he explained, “energy is proportional to the square of velocity, but is only directly proportional to mass.”
This is one time when less really is more. (It's artistically incorrect to say, but usually more is more. By a long shot.)
What my smarter brother meant is that you want the head of the maul to be going as fast as possible when it hits the wood, and although Goliath could have done serious damage with a 10 pound splitting maul, he could have cleaned up Dodge with a six-pounder.
So now I have ice on my thumb, and some time to contemplate the splitting of firewood.
Very few logs will split on the first whack. In fact usually the maul bounces off at first. I call a new log “laughing oak” because it seems to be mocking me. Sometimes the wood just wants to test me, to see if I am worthy to cut it. After all, it has lived 75 or 100 years and has seen a great deal more hardship and change than I have. As I look at the rings on the cross-section, some them are so close together as to almost be on top of each other. Those are the rings denoting scant growth – from years of no rain, or long and bitter winters. Several tight rings together can indicate a prolonged dry spell.
Running my fingers over the rings, I ask the section of trunk to tell me its story. It wants to tell everything.
But it wants to ask everything as well.
If it's going to be used it wants to be used well (and who doesn't?); it wants to be burned for warmth by people and families worthy of its sacrifice. If my intent is selfish, and my heart filled with darkness, then the wood is sad. But even grateful, contented wood doesn’t let the axe in easily. “You may feel free to split me,” it says, “but you must work hard for it, breathe heavy and sweat if you want to earn me. And finally, when you burn me, you must have a character that loves all humankind.”
That last one is the hard part.

Grasshopper, kinetic energy may be proportional to the square of velocity, but kinetic energy is not conserved. Momentum is conserved, and momentum is only directly proportional to velocity. Your lighter head will rebound more, passing the shock into your hand and up your arms, putting you at greater risk of joint damage. A heavier weight allows you to apply the energy more gradually, and for less shock to come back to you. Ohmmmmm.
According to the Zen of Firewood, you would do better to buy some of those glued wood logs at Safeway and keep warm until such time as you are worthy to split those wise logs you were dialoguing with.
Mychal, damn. I had forgotten about the non-conservation of kinetic energy. But my hands and wrists understood it immediately. Since writing my post, I have felt the bounce of the lighter maul and thought there must be some energy going to waste in that. I also noticed that the heavier maul stayed put on the wood much better. So your point is well taken.
Still, there are some situations, like when the grain is straight and uncomplicated and the light maul hits squarely perpendicular to the tree's rings, it yields up a mighty crunch. Also, I can get several more swings-per-corpuscle out of my aging body when using the lighter unit.
I have found it productive to sometimes use the lighter maul to get a fissure opened and then using it as a splitting wedge, drive the back end of the light maul with the blunt end of the heavier one.
There are some drawbacks to this, such as the possibility of the handle of the lighter maul flying up and carving a six-stitch groove out of my chin.
But the whole thing does give me a nice Abe Lincoln feeling.
