I built this circular swingblade sawmill from scratch. The function of the mill is in its name "swingblade" - the blade swings 90 degrees making it possible to cut both ways while moving the carriage up and down the log resulting in dimensional lumber in one pass. I built a chainsaw mill ten years ago and milled lumber that I used for my cabin / sauna house project. Then I built a bandsaw mill five years ago and used the cut lumber to build a partition in my barn I currently call my workshop. Both of them worked great, bandsaw mill was faster than chainsaw mill for sure. But I think I there's an even faster mill and swingblade sawmill in my opinion is just that. There are different types of swingblade sawmills, one type utilizes a railway system where the saw carriage rides on rails so both rails are in the way when loading the logs. This is a beam-type mill where the saw carriage is suspended on a single beam over the log that sits on the ground fixed by a couple of wedges so it doesn't roll off while cutting. There is no need to clamp the log down, there's no need to move and turn the log. Cut depth and width adjustments are all made on the sawmill beam end frames. I think this design is ingenious! And it cuts great!
This sawmill build is based on www.turbosawmill.com "Manual Mill" design and it is patent pending.
