Abstract: A Custom Construction System consisting of a novel structural member in combination with as required, spreader members and equalizer members which are assembled together by various nuts, bolts and other hardware to produce various pieces of furniture and other home improvement projects. The basic structural member consists of a rectangular shaped member having rounded edges and a plurality of bores passing through both its wider and narrower surfaces. The basic structural member and the spreader members can be constructed utilizing a template. The template consists of piece of material having two flanges at approximately a 90.degree. angle with respect to each other. One of the flanges has a rounded end. Both flanges have bores located on their surfaces which are used for marking the location of the bores on workpieces to be converted into structural members and spreader members.
