Set the Logs into Place and Secure
Set the first log in place, resting atop the 1 x 6 baseboard (Image 1). Align the trim nailer to the stud lines drawn on the wall and attach the log with 8-penny nails.
Measure for the height of the outlet box in the second board and notch. Set the board atop the first one (Image 2), overlapping the tongue, and nail in place.
From this point upward, the logs are only cut to length, set into place and secured.
The last board near the ceiling won't have the tongue to nail into, so it can be secured to the wall at the thinner part of the bottom of the log.
