In this final segment, apprentice Matt Rohrer joins up with a crew of experienced log homebuilders to quickly and permanently reassemble the cabin shell created in the previous segment.
Safety Alert: Always wear safety glasses and ear protection when working with chainsaws.1. The logs arrive at the home site where a pre-poured concrete foundation and plywood sub-floor are ready to support the cabin (figure A). For this process, Ron coordinates with a crane operator and rigs up each log in sequence (figure B).
2. After aligning and indexing the position of the base course, Matt helps tack down a strip of insulating plastic sill seam along the perimeter of the sub-floor (figure C).3. After squaring and repositioning the base logs over the sill seam, Matt drills in long lag screws to bolt the base course to the sub-floor (figure D). 4. Gravity plays a major role in the strength of the cabin, but to bolster the cabin laterally, Matt and his crew add support by embedding steel rebar through the base course, and then into the sub-floor (figure E).
5. With the base course set and squared, the crew now quickly stacks up the cabin log-by-log using peavey tools and elbow grease. Just prior to setting each log, Matt and his crewmates place a square of fiberglass insulation into each joint to later minimize energy loss (figure F). They permanently fasten each log to the next by drilling a long lag screw into the intersection (figure G).6. To finish the cabin shell, Matt helps position the members for the roof support (figure H). The crew permanently fastens the gable ends, pillars and posts by toeing in the lag screws.
In the weeks ahead, the homeowner will finish the cabin, seal in between the logs—called chinking, and finally install the roof.
