ABSTRACT:
A mill for guiding the cutting of a chain saw includes a pair of rail members, each rail member comprising a length of C-channel, with a lip joined to the distal edge of one leg of the channel and extending parallel to the web of the channel. At least one hole is disposed in the web of each channel length, and a long bolt extends through the hole to join the rail members in parallel disposition. A plurality of rectangular spacer members of various thicknesses are each provided with a hole therethrough to receive the bolt. The bolt extends through a hole in the chain saw bar near the power head to assemble the rail members and spacer members to the chain saw. The lip of one rail member acts as a rip fence riding on a previously cut edge, with the spacers employed to join the chain saw bar to the rip fence at a selected spacing interval therefrom.
