ABSTRACT:
A guide apparatus is provided for guiding movement of a chain saw in a direction parallel to the longitudinal axis of the bar of the saw through a member in which it is desired to cut an opening with the chain saw. The guide apparatus includes a guide member disposed contiguous to the member to be cut. The guide member has a guide surface thereon which is disposed parallel to the axis of an opening to be cut in the member and parallel to the longitudinal axis of the chain saw. A guide means is provided for engaging the guide surface and guiding relative movement between the guide surface and the guide means in a direction parallel to the longitudinal axis of the bar of the saw. The guide means is supported by a support member which is attached to the chain saw to enable the guide means to guide movement of the chain saw as the guide means moves along the guide surface to enable the chain saw to move in a direction parallel to the axis of the bar to thereby penetrate the member to be cut to establish an opening therein having an axis parallel to and co-extensive with the longitudinal axis of the bar of the saw.
