ABSTRACT:
This invention is related to wood working, more specifically to repairing wooden and or other materials that have round or oval shapes, that have separated at old glue joints, or that have splintered or split. This invention will preferrably be used in conjunction with one-half or three-quarter inch pipe clamps and/or bar clamps, giving multiple clamping pressure points around any size circumference table top, desk top or any other object, circular or oblong. By using this invention, the object to be repaired can be subjected to the constant pressure needed around it's circumference to insure that a proper permanent bond forms between the separated or damaged pieces of wood or other related materials.
