Lifting The Logs
One of the more daunting tasks that we are planning is the lifting of the logs to form the walls. Each log will be 45 feet long and 12 to 15 inches in diameter. We're not sure how much that means they will weigh but it is surely going to require some sort of mechanical lifting device to get them on top of each other to a height of 10 feet or more. We've read about people doing it without needing cranes so we know it can be done but it sure does seem like it will be nearly impossible. We probably think this since we haven't done it yet. Time and time again we have heard of people doing things that seem impossible and as soon as they are taught the proper way to do it, they say it is much easier than they imagined.
When we first started thinking about this, our first thought was to get someone to come in with a crane and lift the logs one by one. That's surely possible however those things rent for about $100 per hour. If we could lift them all in a single day, it might be worth considering. However, since we have to place a row of logs and then
pin them, we will have to drill about 20 half inch holes thru each log. That is 80 holes per round of logs. That will take some time so it is unreasonable to think that the crane is going to be cost justified. We sure don't want to be paying a crane operator to sit there while we drill and pin the logs.
The method that the Log House Builders Association advocates is to erect 4 poles (one at each corner) and then use a block and tackle at the top of each one to lift the logs. They say that this can be done by one person.
These pictures are from another log house builder up here in Washington. His name is Paul Kahle and he has been using this technique with success.
As you can see, he was able to lift the logs and place them perfectly by only using that block and tackle. He says he did need a wench that was mounted on his truck for the bigger ones.
These pictures pretty much take you all the way thru his building of the walls and give you a pretty good idea of how he did it.
