The mill attachment consists of a pair of guide rails which are attached to the bar of the chainsaw. The rails ride for the first cut on a plank or on a metal ladder which is screwed to the log (but not so tightly that the guide is pulled out of plane), and then on the previously cut surface of the log, and guide the chainsaw blade through the log at a consistent depth so that planks of a chosen thickness are cut. The distance between the rails and the bar determines this thickness and it can be adjusted by moving the rails along a post at each end of the mill attachment. During use it is important that the rails extend out past the ends of the log so the cut has support the entire time. [4]

Small mills use a single chainsaw and can be handled by a single operator. Larger mills use two chainsaw power heads, one on either side of the attachment, and these require two operators. This larger style of mill needs a special bar which allows the two chainsaw heads to be attached at either end. The length of the bar decides the width of the plank that can be cut, up to 34 inches (86 cm), so for logs with a large diameter, the longer bar is necessary. Also, to waste less wood due to the kerf width, a special chain is designed to make rip cuts rather than the usual chainsaw chain which is for cross-cutting.
