I missed this post last night. Your mill is similar to my Woodmizer as well as the Woodland Mills series, and a few other "budget" mills by various manufacturers. They all work on the same principle to achieve the same goal... a carriage running down the track, with an engine to spin the blade, turning logs into lumber.I reread all the posts and noticed no one mentioned a small manual mill. I have purchased a Hudson Sawyer mill. Max size as purchased is 21 inch diameter and 9 ft length. Works pretty good I have to say. I have 12 logs 8 to 12 ft long and 12 to 20 inch diameter. But to test and learn my neighbor who cut a couple pine trees down volunteered them.
