Dowel rod is a must. Once you drill a hole in the tip for the dowel, drill a small hole in the barrel channel perpendicular to the dowel hole. Example: If you drill a 1 inch hole for the dowel, Drill the small hole 1 inch frm the surface to be glued. This will allow air to escape when the dowel rod is inserted into it's hole. This will keep the air from compressing and splitting the tip. Do this in the stock barrel channel as well. A small amount of glue will squirt from the "breather"
Use a pair of heavy duty wire cutters on a small nail and make a two pointed sharpened pin. About 1/2 inch long. Drive the pin into the stock on the surface to be glued. When you are ready to mount the ebony tip, after applying
the glue, use a hammer and tap the tip onto the stock. This will keep the tip from rotating once mounted. The dowel rod will act as a guide. Acetone is a good idea as well
