Abstract: This mill comprises two parallel guide rails which are releasably attached to the upper ends of two spaced, vertically disposed end frames, the lower ends of which are releasably attached to two parallel, elongate skid members, which can be dragged along the surface of the ground to move the mill from one site to another. Two pointed log pins are carried by vertically adjustable blocks on the two end frames, with the pointed ends of the pins facing toward each other to be engageable in opposite ends of a log for supporting a log above the ground, and beneath the two guide rails. A chain saw carriage, which is slidable on the guide rails, supports a chain saw beneath the rails to have its cutting chain travel in a generally horizontal plane, and in position to cut elongate strips from a log when the carriage is moved manually from one end of the guide rails to the other. A device is also provided for adjusting the chain saw vertically on the carriage.
