I have a handle on a stick tang knife that I'm just about ready to assemble. I have a brass guard, a 1" piece of light colored weathered antler, and a 4" brown antler crown. They're all fitted to the tang and fit up pretty tight. I wasn't planning on pins, just epoxy. Should I glue one piece at a time, or stack them all and glue at once? I will have to finish profiling the pieces of antler to the guard and to each other. I assume there's no way to do this without first gluing it all together? Never done a multi piece handle before.
