Update on Cabin build- Done insulating the East side. Had some tar paper get torn up with the wind over the weekend, but no biggie. Discussing the ventilation holes and cap ventilation. Also will change from "built up roof" / "stepped roof" to just a thick roof with one layer. I won't insulate the overhangs, but the roof will look better from the ground. It'll also make it easier to install drip edge. Cost a little bit more, but that won't matter in the long run.
I discovered that my state says the roof must be insulated to R30 (I thought it was R40). This info changes my plans- I no longer need to shave these panels flat because I no longer have to get 9" of foam in place- I only need 7 or 8 inches- this gives me more vertical space between the foam and the plywood. It also means the thickness/height of the foam can vary more, so I don't need to worry about the foam being perfectly flat.
But I also need to fit a 48" wide panel in a 46.5" space (sleepers/ribs must be 48" on center to allow the plywood to attach). So I turned my foam cutter sideways.
Answers the problem not being able to measure how far to cut the roof decking while up on the roof. This would be easier with a man-lift, but with just one person and no man-lift, it becomes dangerous to try to lean out over the edge and measure how far the rafter is from the edge. Roof decking is now trimmed.
A demonstration of the foam cutter I made from Nichrome wire, part of my scaffolding, and a variable power controller. I have to cut 1400 cu ft of foam into uniform thicknesses to install on my roof as insulation. The decking on the roof is complete, the underlayment is in place. I have enough 2x10's to box in this foam. Just need this foam insulation, covered over by plywood / OSB, tar paper, and then shingles, and the roof will be complete!
Note: I'm just a regular guy building a log home from scratch. I have no professional construction experience. I'm just good at following directions.
How I ended up getting the decking up on the roof. Wasn't easy, but this is how I did it. Blog: https://loghomejourney.wordpress.com/
- I wanted to do 20 or 30 boards at a time, but this proved unfeasible. Each board weighs about 30-40 lbs, so 20 or 30 would weigh 600 - 1200 lbs. I didn't feel like the existing decking could take that much weigh dragging over it- would definitely tear up the edge.
- I thought about building a small crane, but this would've taken days to do.
- Also, with the above ideas- the roof can only handle so much weight concentrated in one spot- it's engineered to withstand about 180 lbs/sq ft. With the boards being 16' long, I can only get 2 stacks of them on the 58' roof and still have room to put more up (16' on one edge, 16' on the other, 16' space in the middle to bring more up = 48'.
- Along with this, I stacked them directly over where the rafters meet the walls for maximum capacity. This way, I was able to get about 60 boards ready to install at at time.
After installing the Ridge Pole, we had the crane operator release the pressure on it, and it immediately "rolled" a bit. This video shows how we rolled it back to center. Then I installed more rebar pins in it, and it is holding up very well. Blog: https://loghomejourney.wordpress.com/
installing rafters on my cabin using a crane and the correct spreader bar - 20 feet. Much easier than with a narrow spreader bar. Blog: https://loghomejourney.wordpress.com/
installing quick release pins on the straps from the crane for lifting rafters- saves having to climb up 30 feet to release the straps. The pins can easily be pulled out from the ground via a long string. Blog: https://loghomejourney.wordpress.com/
We hired a guy with a nice pretty crane to help install our Ridge Pole (RP) because the cost of buying stronger chains and heavier equipment was the same as paying him to do it, and he could do in a day what would take us a month. With winter coming on, we want to get this thing dried in ASAP. The plan was to install rafters and RP at the same time, but when he released pressure on the RP, the RP decided it didn't like its position and rolled to about "1 o'clock". Crane guy got scared, and pulled off the job. Told me to call him when I got the RP stabilized. Fast forward 10 days- after a week of rain, and making a new pair of rafters, stabilizing the RP with a chain hoist, shims and more rebar, we are now ready for the crane again. Didn't turn out like we thought, but it will turn out alright in the end.
cutting a rafter for my cabin with the Hud-Son Oscar 121 sawmill. The saw came with a 12 foot track, but I need to make 26 foot rafters, so I welded another 18 feet of track for a total of 30 feet of track, along with extra log dogs. a 4"x12"x26' rafter costs around $300 from the mill or lumber store, and for 28 rafters, that's about $9,000. I got this sawmill for a few thousand dollars, so I'm saving about $7,000 on the rafters by making them myself. This will help keep the total cost of this cabin down to about $20 per square foot - around $60,000 for a 3,200 sq ft log home. see my blog: https://loghomejourney.wordpress.com/2018/08/24/cutting-rafters/
just a small clip of a picnic I played for this week with some friends. nothing special, but sure enjoy playing this type of music- guitar, banjo, autoharp, accordion.
I cut down this 56' long Sweet Gum last fall, and then couldn't even budge it with my tractor. It is 29" at the base, 14" at the tip, and it's estimated weight is close to 10,000 lbs. It will be installed at the peak of the roof, and hold up the rafters.
Using a 30' track I welded from 2"x2"x1/4" angle steel to extend the track for a Hudson-Oscar 121 sawmill I bought from a friend. I'll use this sawmill and track to mill my own 4"x12"x28' rafters from logs on my property. I need 28 rafters and they cost about $300 each, so that would be about $8500. This mill and track was much less than that, so I'm saving money. Made my own log dogs for the track, as well.
unloading a shipping container- used for storing tools and equipment for my log cabin during the build. Even the tractor fits inside.
