Hi David, There is a screw extractor that is a tube with reverse saw teeth at each end. Put it in a reversible drill and it will go through the rail and leave a .250" hole is rail and dowel. Plug with a plug or dowel, redrill and put in a new screw. The screws are longer than those available from the supply houses unless they come from APSCo? Alternatively you can use a very small bit and drill a series of small hole around the parimiter of the screw stubs and punch the remainder out. I like the first way though. The extractors are available from several woodworking supply houses. Newton
