Very interesting project to watch Erkka, and I laughed when you pulled the beer from your pocket at the end of the video. I have often done this process before, using only a chainsaw, and yet, it is mostly the same. We would make quick benches, tables and such for our wilderness camps. Even with the power of the chainsaw, it is still important to observe the proper grain of the wood, to make the best pieces and avoid accidents. You must also use wedges, to prevent the chain from binding in the middle of the cut. We would quickly make wedges using an axe, or use the plastic orange professional ones. For an inexperienced worker, it could be somewhat frightening to constantly move the wedges up the cut as the sawyer works the spinning chain towards your hands. But using this method, a log that size could be split in about 5 minutes. Of course, the old methods are often more satisfying. Anyway, great project! Can't wait to see what you work on next :)
