I have just recently discovered your site and I will be asking all sorts of advice and hopefully I can use everyone elses expertise to learn the things I don't know. I figured if you were willing to share with me then I should respond by sharing my expertise with anyone who may want it. I am a log home builder that uses the scandanavian full scribe (cope), shrink fit saddle notch method. I also build all my own roof trusses, purlins and post from round log with a mortise and tenon joinery system( all wood no nails or screws ). This method wastes almost nothing and can be done completely by hand in the bush and requires almost no outside materials. If you have trees a strong back and are good a freecycling (windows, doors, and roofing) you can build a stunning home for next to nothing. If anyone has any questions regarding tools, techniques or materials please just ask and I will do my best to help.
