The leaf is made up of two central boards and two strips of oak edging these at either end. The central boards have separated and lost dimension due to shrinkage and a previous poor repair.The edges are rejointed with use of a router and the loss of material made up with a thin strip of oak cut into the joint.The thin strip is glued up first to one side with use of hide glue.When this has gone of further strength is added with biscuit joints,the two halves can then be assembled and glued up again with hide glue.The two strips of oak at either end have been cut to release the central boards again from a previous shoddy repair,this unfortunately renders them useless.Replacement end strips are made from old well seasoned quarter cut oak. These are tongue and grooved into the central boards and the oak substrate is completed.
