Restoring Antiques (Cont'd)

Some dents may have the fibers of the wood so badly crushed and broken that they will not respond to the steam treatment. Those really deep gouges, splintered areas and dents can be repaired by inlaying a similar species of wood. To save a lot of work and trouble during the final finishing phases, match the color of the bare woods as nearly as possible. If the colors match closely enough, the need for spot staining and color blending will be eliminated. Grain patterns should be matched as nearly as possible. The success of making an almost invisible inlay rests almost entirely on grain match. A patch whose grain runs against that of the general surrounding areas is immediately apparent under the final finish.

An inlayed patch must fit so that there is continuous contact all around the edges and this requires skill and know-how plus a lot of patience. The damaged area should be excavated no deeper and no larger than is absolutely necessary, usually a % in. or so. A boat shaped or double wedge patch, as shown in the sketch, will attract less attention and blend better than one with square ends. A cardinal rule is to always make the patch thicker than the depth of the hole so that when glued in place it will stand slightly above the adjacent surface. The edges of the excavation and those of the patch slope inwards, with those of the patch being cut at a somewhat lesser angle than the sides of the excavation. Then when the patch is fitted and glued into place, and pressure is applied by clamps or weights, these edges are brought into contact all around the periphery of the patch. The angles should be cut so that the area of contact is at least '/a in. wide. As pressure is applied on the patch, the wood fibers of the edges on both sides will be crushed slightly and will close any small irregularities along the line of contact. After the patch is cut down and sanded level with the surrounding surfaces, only a minute line will reveal where the patch meets the repaired surface. If a really good grain match has been made, this line will be almost impossible to detect.

Next issue we will continue with stripping and finishing techniques. W\\j
