Power saw guide kit

DETAILED DESCRIPTION The instant invention supplies the above-stated need.
It is based on the square that the carpenter already owns, and in its kit form, which is the most easily described, it comprises a pair of elongated open channels and a slidable rod in each of the channels with a set screw in the channel to fix the rod at a selected length of extension from the end of the channel.
The kit includes means to mount each channel on one of the legs of the carpenter's square so that the two channels are not only on opposite legs, but on opposite faces of the flat sheet metal that characterizes carpenter's squares.
Each of the rods is extended out beyond the corner where the two legs join, a distance equal to the spacing between the sole plate of the saw which typically it rides on the fence, and the cutting plane of the rotating blade.
Now all the carpenter has to do is to make a mark on a board edge indicating where the right angle cut should be made, and align the distal end of the respective rod with the check mark, and, using the carpenter's square itself as the saw fence, draw the saw across the board, where it makes an even orthogonal cut right at the tip of the respective rod extending from the channel.
Provided the rod tip is at the cut-off check mark, there is no doubt that the cut will be at the right place, and the use of the carpenter's square as the saw guide insurers orthogonality of the cut.
There is no need to try to see past the safety guide, and no (or at least less) temptation to remove it.
Structure is also provided in the kit to ensure that the mounting of the channels on the square can be done to accommodate both left and right handed carpenters.
