Abstract:
1. A sawmill having a saw blade which can move between a substantially horizontal cutting position and a substantially vertical cutting position, the sawmill having a control arm which operates to move the blade between the substantially horizontal and vertical cutting positions, the control arm being mounted for pivotal movement about an axis, there being runner means which runs along a side part of the control arm to push the control arm to cause the control arm to pivot about the axis and move the blade between the cutting positions; the runner means being such that it is able to cause the control arm to move to one of the cutting positions at which time it bears against the control arm to lock the blade in that position; the sawmill formed such that the side part of the control arm provides a raceway against which the runner means runs as the blade is moving between the cutting positions, the control arm having a second side part, the first and second mentioned side parts each having a flared portion and wherein the runner means can be moved to bear down against the flared portions in turn to lock the blade in one of the two cutting positions respectively.
