The school project model log cabin uses horizontal logs which are notched to fit at the corners |
In
'Joan's Summer' the two girls, with help from the Blackburn family,
build a log cabin. This, for couple of twelve year old girls is a big
project, but not impossible, but the building process must seem
complicated so here is a simple explanation.
When
Heather and our family moved to Saltspring Island the first thing we
built after the pumphouse and the barn was a piece en piece style log
cabin. We had cut our lodgepole pine logs in the Okanagan where we
had lived previously and brought them with us. Like Patti and Joan
our first job was to clear a building space and make foundations. In
our case we poured concrete bases on the uneven rocky ground and then
placed cedar posts of different lengths on top and levelled their
tops. In the girl's project they used some big rocks they found
nearby and levelled them by digging the holes to different depths. We
cut down some fir trees and rolled and levered these sill logs into
position on the cedar posts. The corners were notched to fit
together. With dad's help the girls did much the same. Good
foundations that keep the bottom logs off the damp ground means that
the cabin will not rot from the bottom up!
To
work on the walls we really needed to have the cabin floor in place
so we could stand on it and work safely. We flattened the inside
faces of the sill logs and levelled and then nailed boards to them
and then installed the floor joists and the plywood floor. Our cabin
was twenty by thirty feet and Joan's cabin was eight by twelve feet (
three sheets of plywood).

The vertical posts are cut to length and the vertical slots or mortices are cut with a chain saw |
The
upright posts had long slots, or mortices cut lengthwise and they
were then placed upright on the sill logs, pinned using rebar, and
then braced vertically on the corners and along the sides of the
cabin.
Unlike
the usual log cabin which relies on the stacking of horizontal logs
to hold up the roof, a piece and piece style is a post and beam
structure and the log walls simply fill the space between the posts.
One could use a variety of different materials for this - sticks and
mud, adobe, rock masonry, cordwood, glass, hay bales, you name it.
In our case and in Joan's cabin the walls could be built of already
available, small diameter and short-lengthed, easily lifted logs.
Once the logs had the bark skinned off ( no bugs to eat the wood
under the bark if they are skinned) they were cut to length and the
ends cut into a tenon ( or tongue) that would slide down the mortice
( or groove) in the upright posts. All this cutting could be done in
an assembly line sort of way using simple tools, - a saw, a
carpenters square, a level and an axe. In our cabin we also
scribe-fitted each log to fit the shape of the one below and placed a
strip of insulation between them. With Joan's, the girls simply
stacked them into a wall and the later dad ran his chainsaw down the
gap between each log to get a tighter fit. Later they would use some
mortar to chink them some more and make the cabin weather proof.

Each filler log that fits between the posts have a tenon cut on the ends |
So
the work for the girls involved skinning the logs once Little Guy had
dragged them to the building site, cutting them to fit between the
posts and making tenons on the ends. When Patti was away at the
riding stables, Joan could do all this by herself. Together, they
could then lift them into position. What might seem like an
impossible task for the girls could be broken down into manageable
parts.
|
Once the logs are have their ends tenoned they can be lifted up and slid down the slots in the upright posts. Notice the temporary bracing that holds the posts vertical. |
Then
the roof and wall top beams were raised and the rafters and roofing
nailed into place. Dad had some old pieces of galvanized metal
roofing that would do the job even if they look a little rough on top
of the beautiful newly skinned logs. The basic frame was up, but of
course for any builder that is really just the beginning - all the
picky work of finishing still lies ahead! For this simple cabin
however, there would be no electricity or plumbing, just the most
basic furnishings, a ceiling and a woodstove. Once Joan left for the
city, between Jamie and Dad all that could be finished before the
snow flew!
|
Once the walls are completed the roof frame is built. The top logs for the walls and the ridge pole and then the rafters are raised and pined and nailed in place. |
For
Joan though, she had already built a visible HOME and had done much
of this by herself. A real accomplishment in the midst of her
troubled times. And she will be back!
|
By the time Joan comes back to the farm in the winter, the ceiling and furniture, the stove, window and door will be ready. Joan will walk into her warm cabin with an armload of firewood, shed her outdoor clothes and settle down to enjoy that wonderful feeling of being HOME! |
