For many years I have had excellant results repairing large and small holes using strips of wood sliced from a piece of hammer shank or a round toothpick. When I think it important to preserve the centerline of the hole, as in your case for example, I prepare three slivers just long enough to be flush with the top of the hole when fully inserted, coat each with glue (white glue such as Titebond) and try to arrange them about 120 degrees apart in the hole. Immediately (ie don't wait for the glue to set) put the screw in the hole and tighten down to a depth it would normally be. The screw serves as a clamp to make a good bond between what's left of the slivers and the wood of the hole. Wipe off excess glue. If the wood still has integrity for a good glue bond this will be a good fix. In most such repairs the parts can be immediately screwed together, such as leg and lyre screws. I had not heard of the leather strip repair before and will probably try it one of these days. Travis Gordy --------------------------------------------------------------- > > >
