This is a system/method of clamping or securing or connecting one or more objects together in a wide variety of ways with the main means being a specifically designed bar and mated slot combination. While the main embodiment is the "Handy Table" project, there are many other ramifications of this invention. The bar and slot design can be altered to perform many other tasks where some way of attaching one or more objects to another need be accomplished. The main embodiment is, in my estimation, the most advanced type of work or project surface. The combination of a tri-sectional work surface, adjustable in a variety of ways, in size, in tilting, in multi-angle clamping capability, in precision height adjustment, and in the ability to transport the object being worked on easily, plus the addition of accessaries that enhance the overall capabilities of the "Handy Table", make it useable by many different professions and by the average project worker, be it man or woman, young or old.
