This is one of two pedestal bases that support a dining table.The curved Sabre leg is housed in a dovetail joint in the main column.These joints will often fail over time due to the constant pressure upon them from the weight of the table.When reglueing it is importance to clamp the joint,so that continued pressure can be applied while the glue is drying out.With this being a curved surface a jig is made to turn a curve into a square clamping surface.
