Abstract: A log turning machine is described in which a support frame mounts a rotary cutter with a log receiving opening positioned to receive an elongated log workpiece that is moved relative to the support frame in a forward direction of travel along an axis. The rotary cutter is operable to cut the log workpiece to a prescribed diameter centered on the axis. A set of elongated guide members having opposed first and second ends are mounted to the support frame by sets of links for adjustable movement substantially radially with respect to the axis between a minimum and a maximum cutting diameter. The first ends of the guide members are positioned downstream of and adjacent the rotary cutter and extend substantially parallel to the axis by a distance that is a multiple of the maximum cutting diameter. Guide member positioners operatively connect at least some of the guide members and support frame to enable selective adjustment of the guide members substantially radially between the minimum and maximum diameter. A cutter head and support frame adjuster may also be provided to enable positioning of the cutter head and axis for adjustment of the cutting diameter relative to a log infeed plane.
