Abstract:
A foot for a chainsaw adapted to support the chainsaw for making headcuts in rafters, said chainsaw including a guidebar to support the circulation of a cutting chain in a direction away from the operator defining an upped cutting edge for the chainsaw and in a direction toward the operator defining a lower cutting edge for the chain saw, said support comprising:a flat baseplate to rest upon the rafters during cutting, the baseplate having an aperture;a hinge disposed on the baseplate and supporting a clamp for pivotal motion about an axis, said clamp having spaced arms to pass the chainsaw guidebar there between and through the aperture, a backing plate on one arm to support the guidebar and threaded screws on the other arm adapted to contact but not penetrate through the guidebar to clamp the guidebar against the backing plate and to the clamp, said guidebar when clamped adapted to pivot about said axis from a vertical position to approximately 75 degrees from the vertical;an adjustment bracket upstanding from the baseplate proximate the aperture, said bracket including an arcuate slot having a radius centered at said axis;a threaded stud secured to the backing plate and passing through the slot to receive a wingnut to secure the position of the stud, clamp and the angular position of guidebar relative to the baseplate, whereby the chainsaw is positioned to cut the rafters with the upper cutting edge with the weight of the chainsaw supported by the baseplate and while moving in a direction parallel to said axis.
