11x15 cabin build part 5

Here are a couple of pictures of the subfloor. It is 3/4 " tounge and groove OSB. I just nailed it down with 8 penny ring shank nails.

Another picture of the subfloor. Later, I will put down a finish floor.

The picture below shows preparation for cutting the window opening in the back wall. A couple of boards screwed to the logs will keep the logs in place after the cuts are made. The logs are very dry so I am not making any allowances for shrinkage.

temporary boards

I drew lines on the logs where the cuts would be and just cut them with the chainsaw, keeping the cut perpendicular to the wall as best I could by eye. The hole is slightly larger than the window frame dimensions. I allowed about an extra 1/2 inch in each dimension.

The edges of the logs were beveled with the saw. Later, this area will be chinked or caulked.


bevel logs
Here is the window frame which is just 4 boards fastened together with screws. The boards are 7 inches wide which is the same dimension as the wall thickness.

Here is the frame installed. Shims are used to postion the frame so that it will be square and plumb/level. Shims are needed between the fram and each log end. 4 inch screws driven through the frame into the logs will support the log ends after the temporary boards are removed.

The front door opening required cutting part way into this log. This was fairly time consuming and took a lot of hammer and chisel work. The top edges of the openings have a bevel also.

Later, I will build sashes for the windows and a door.
