Firewood. part 2: Splitting, stacking and air drying
I
have now begun the splitting phase of my firewood project. A big job
in itself, but if I take it a bit at a time and spin it out over a
couple of weeks it will get done. I do not get myself into a lather
and out of breath however, no blistered hands and aching back, but
when I am splitting I am very productive, because I have done this
job all my life and have developed a style that gets the best out of
the splitting maul and the special characteristics of trees.
Firstly,
when handling the maul, which is not an axe but is designed for
splitting, I do not grip it tightly and use all my force but rather
swing it smoothly and guide it accurately. A careful blow, aimed
precisely in the right place will cause the wood to spring apart,
while one swung hard but a half inch to one side will either bounce
off or jamb in the wood . A steady rhythm, a calm and focused mind
will see the wood pile grow as if by magic. If this sounds like the
Zen of.... , or the Tao of..., you would be right!
It
makes a big difference whether the species will split cleanly ( like
maple) or will cling and resist the maul's attempt to force pieces
apart, (like fir). How the tree has grown at this particular section
of its trunk makes a big difference; wood that has grown under
tension, or which has twisted fibres, can be very difficult. Knots
are impossible to spit through and must be worked around. A knot is a
branch that began when the tree was small and so extends from the
centre core right out to the bark; you cannot split across it (well,
never say never). So, if making firewood is this difficult why start
at all? Because there is a way.
The
most important part of the tree for splitting purposes is the middle
of the growth rings, the bulls eye. Notice that this is not
necessarily the centre of the tree because a tree does not usually
grow symmetrically, even the rings will be wider on one side and more
tightly packed on the other, and that will affect how it will split.
That centre eye is critical to smooth splitting. One might say that
centring oneself takes place in unity with each separate piece and
its own true centre. When both are in alignment the blow falls and the
wood comes smoothly apart. ( see Tao of...). I'm making a joke out
of this, but it is true never-the-less.
A smaller piece, chopped through the eye |
A
small diameter piece needs a different approach from a larger one, so
a simple blow directly across the end and through the eye will
break it into two halves and these pieces will also split once more
through the central eye. Miss that centre however and even a small
diameter piece will resist splitting and you will find yourself with
the piece of wood jammed securely on your maul. The temptation will
be to lift the whole mass and bang it down again to force the split.
This might work of course but is bad form and should only be
performed in secret! Then you pick up the pieces and chuck them away
from your work site because stumbling over wood underfoot is
dangerous and upsets the even tenor of the work. For small pieces its
a good idea to place them on a larger round as a chopping block
because your blow will be more effective if much of the energy is not
absorbed by the soft ground. Closer to hand too!
The completed pile of wood |
The big grand fir was beginning to rot in the centre |
Progressively removing pieces off the outside |
An
alternate approach for a large round is to begin, not with a split
across the centre eye, but with a series of smaller pieces peeled off
the outer edge, following the direction of the growth lines. One must
avoid knots of course, but things usually go smoothly, and then the
final smaller centre section can be split across into pie shaped
pieces. This technique is particularly useful when there is some
resistance to beginning with a split directly across the round as in
the previous example.
Completion of that round! |
When
I have finished splitting there will be some particularly awkward
pieces that have complicated knots or cross grains. I will use steel
wedges to beat them into submission or cut them up with the chain
saw, whichever works the fastest. ( No Zen here!)
That little knot needed extra force |
Although
I haven’t begun yet, I will describe the reasons for building the
woodpile and drying the firewood in the forest. Of course I could
just throw the wood into rough piles and then immediately haul them
up to my woodshed and stack them just once. I don't do that for
several reasons: wood fresh from the tree is heavy and my VW van
which has to double as a truck would not carry much in each individual
load; loading and unloading would be heavy work too, especially for
my back, and tightly packed wood in a shed would not dry well, even
through the dry summer months. Dry wood is essential for proper
burning!
Wood
that is stacked in a sunny place ( like the clearing you have made
just by cutting down the trees), just two rows wide, four feet high and as long as you like, with some plastic tarp or old
metal roofing to keep the rain off will loose a lot of its weight
with the sun beating down and wind free to blow through it. Then in
the Fall, before the winter rains make the forest road soft and
slippery I pack the the Winter's firewood up the hill and stack the
now dry wood into the wood shed which is within a short walk of the
house. Mind you do not stack you firewood against the house ( think
of those wood eating bugs) or have your wood pile or shed too close
to the house ( think forest fire and all those combustibles so close
to home.) And, happy wooding!
