Terry, Your friend may be interested in this little tidbit :) I posted this little idea on this list a while back. First, make small pattern of the bridge holes for later use. Next use a hollow screw extractor like Issac suggests. Remember, the pin is at an angle. There is no way to really do a nice neat job at this phase of the repair. Once the root canal is done, fill the hole with a dowel, glue in and trim flush with the top of the bridge. The purpose of the dowel is solely to provide some material for a 1/2" forstner bit brad point to center on. Next, use your 1/2" plug cutter to make a maple plug (1/2" should work). Note the direction of the maple material as to planing with and not against the grain, and mark your plug accordingly. With the forstner, drill down to a depth a bit less than the height of your plug. Glue in your plug; it should stick up a bit and will extend partly into the notch area. Trim down with a sharp chisel, sand smooth and DAG the area. Next re-drill your bridge hole (or two holes) and chisel-cut the notch in your usual way. See photos.

The top (broken end) of the bit is about 1/8" below the top of the bridge. Any suggestions short of gouging out a hunk of bridge? If I get a good suggestion, I'll pass it on to my "friend". ;-( Thanks! Terry Farrell </blockquote></div> -- Nick Gravagne, RPT AST Mechanical Engineering
