11x15 cabin build part 3
Two logs are 22' feet long. These will extend beyond the front wall
about 6 feet for a small porch and beyond the back wall by
foot. The rafters will go on these logs. The notches for these longer
logs are not near the end. To make the notches, the plywood end block
is removed from the jig which allows it to slide down the log to the
proper location. The jigs have to be fastened at the same spacing as
was used for all of the 15' logs cut previously.
The photo above shows me cutting the underside notch. Nothing different
here- this is the same way the other notches were cut.
However, for the upper notch, the saw can not enter the log from the
end so it is necessary to make multiple cuts perpendicular to the notch
surface. The cuts shown above were made with the jig in place. The jig
provided a "stop" to keep from cutting too deep.
Some chisel work and the notch is finished.
As luck would have it, this notch happened to be right where
knot was. This is a weak area anyway so I will have to be careful when
working on the porch roof to make sure this log is well supported.
.The tractor makes quick work of setting these logs.
Notice that I did use short logs on the front wall to form a
small opening. This allowed me to use some shorter logs I had leftover
as well as giving access to the inside. Later, I will enlarge this
opening for the door and cut openings for windows.
