As the song says, “I started out with nothing, and I’ve got most of it left.”
Those lyrics summed up my feelings since starting this log cabin project in February. I all I had to show for my effort was a bunch of skinned logs scattered through the woods and fields. That all changed this summer. Here’s the progress as of mid July…
Setting Sill Logs
I had my doubts about dry-stacked stone piers as my foundation. The largest sill log measured 14 inches in diameter by 18 feet long. A handy online log calculator estimated the weight for this one log to be 925 pounds. The stones/boulders were far from flat. I did my best to shim them with smaller stones to keep them steady.
I spent way too much time with a water level trying to ensure all the piers were the same height. Round logs are not dimensional lumber. Get the stones close to the same height and lay logs on top.
In all honesty, my plan was to use only hand tools for this trial of self-reliance. Trees were felled and bucked with an ax, debarked with a bark spud and draw knife, and hauled to site by me as the mule pulling my LogRite Junior Arch… until I attempted to move those half-ton sill logs. A real mule was needed for this job.
My best friend Philip had just finished skinning the two sill logs when Allen, the land owner, walked up to visit. He told us he had just acquired a Kawasaki Mule. Perfect!
Even with Junior hooked to the back-end of the Mule, the big sill logs were a beast to haul back to the cabin site. But it worked!
Log Lifting Tripod
Lifting close to a half a ton of wood, even a few feet off the ground, would require a lot of mechanical advantage using simple machines. Dead cedars were cut and lashed together to form a tripod. The largest leg/pole was about 6 inches in diameter. Standing this heavy tripod up by myself was like watching the Three Stooges. Wish I had filmed this for some comic relief.
Here’s the video of how I lashed the tripod for those interested…
After positioning the tripod over the heaviest sill log, I attached a four-to-one block and tackle system at the top of the tripod. Upon testing the pulley system, I could only lift the log a couple of inches. Not good. I quickly realized that, even if I was able to lift the log, I could not hold the log in place by myself and control the placement on the piers with precision. I needed a lifting device I could control when working alone. I bought a one-ton chain fall (hoist) for $60 the next day. This one tool revolutionized the job!
Our video below shows how maneuverable the logs are when choked at the balance point.
Sill Logs Notched and Set
I positioned the first sill log on the ground next to the piers to mark for notching. I made relief cuts with my bow saw on each mark about one inch deep. I used a boy’s ax to remove wood chips between the saw cuts. This produced a flat surface for the log to rest on the non-flat stone piers.
I re-choked the log with the tow strap near the bottom of the log. Lifting by myself with the chain fall, the log slowly turned until the notches faced down. Then the log was lifted to the height needed to be lowered onto the piers. On the way up, the log scraped the side of the piers toppling a few. I re-stacked them and lowered the log cautiously. They held up fine but had a touch of wobble. Small rock shims were inserted to steady the piers.
After months of preparation, the feeling of seeing a huge log off the ground and resting on rocks was pure excitement!
The next day I set the second log to create the first corner. How do you make corners square using different sized logs which are not even? Here’s how I did it…
I’ve used the Pythagorean Theorem many times to square corners using dimensional lumber. You need straight lines for this to work. I popped a chalkline down the center of each log. I tacked a nail at the intersection where the two lines crossed in the corner. From that corner nail, I measured three feet down the chalkline and tacked another nail. On the other log, I measured four feet and drove in a nail. I lifted the second log just enough to allow me swing in or out until the distance from both nails measured five feet. This creates a 3-4-5 right triangle ensuring the logs are perpendicular in the corner. A 6-8-10 triangle would be more accurate, but I was by myself and didn’t want to stretch a tape measure 10 feet from nail to nail.
The Butt and Pass method requires no notches. Metal pins hold the logs together to create a sturdy, solid structure.
I cut 1/2 inch rebar in 20 inch lengths at my shop. Back at the build site, I use a brace and bit to bore a 1/2 inch hole almost through the first log. Probably should drill all the way through but almost through seems to work. Now I drive the pin through the pilot hole and into the adjacent log. I started using a 6 pound sledge with a 36 inch handle. My accuracy suffered. The long handle also kissed my ribcage a few times while hammering bent over. We sawed the handle in half and found it to be the ticket.
A note worth mentioning on driving pins. If you miss hit and bend the pin, stop. Straighten the pin as best as possible before pounding more. A bent pin will find its way through the side or top of the adjacent log. Once all four corners were pinned together, the sill logs became unbelievably steady on the piers.
Log Floor Joists
I’ve begun hewing log floor joists. Dimensional lumber would speed up the process but I want to use as many raw resources as possible on the cabin. One side of a log gets hewn flat and notched with tenons on both ends. The tenons will mate with mortises notched into the sill logs. I’ll do a more detailed article on what I’ve got planned for the floor system.
Until then, here’s our latest video on the floor system…
