ABSTRACT:
An auxiliary pressure clamp is provided for a bar clamp structure on an internally threaded sleeve for adjustably engaging an elongated bar of the bar clamp at a right angle thereto. A force-applying screw is threaded into the sleeve and has a handle at another end to rotate the force applying screw within the sleeve. A head will engage with a work place at a right angle to the clamping action of the bar clamp to apply pressure thereto, especially when various parts of the work piece are being glued together, or a veneer is being glued to a surface of a work piece.
