You may get lucky and the kerf of the hole saw will allow you to use the piece/plug you cut out. Steam the bow, put the plug back in the hole and bend the bow around it to tighten it back up. I'm going to try that with mine but I still won't get a real nice glue line I don't think. I'll post a picture after I clamp it all up. Oh, timer went, steaming is done, time to clamp it up.
