The arrow cut or joints can be used in various places. Some of the advantages of the present invention are as follows: The parts are self-aligning, straight joints are eliminated, increased strength is provided in the taper or arrow cut because there are no right angle cuts. Further, the rows of logs are alternately pointed in opposite directions and there will be no daylight in joints and no heat loss. Exact corners are assured, and it will be impossible to point logs in the wrong direction. The logs may be numbered by the piece to facilitate construction.

As to manufacturing, in addition to the previously described advantages for use in erecting a building, in manufacturing, the process or apparatus of the present invention permits logs to be cut in one direction and allow for each measure of each row. Further, there will be minimum waste, since random lengths and widths of logs can be used. Any length or width of house can be cut and mass production can be utilized. Only two measurements are needed such as for cutting four walls. It is not necessary to turn the logs over or end-for-end while cutting. The arrow point fits into the notch of the corner or into the feather end of another log. The arrow out can be used in the manufacture of log cabins, homes, motels, ski lodges, restaurants, stables. garages, alps buildings or any other type of log structure.

Having thus described the preferred embodiment of tize invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
