Brent explains the process of rough milling wood. Making windows and doors starts in the rough mill. Hull’s process starts by taking rough lumber from a saw mill and then smoothing, cutting and milling the rough wood into smooth blanks. The tour starts in the rough mill showing the shop, planers, joiners and other machines. Then he shows the finish mill, the shapers, the set ups and how mortise and tenon joints are cut. Machine junkies enjoy.
