Hey, so i was thinking about making some bone heads, but i noticed that most of the time the bone heads will be around 50 grains. so to increase weight i was thinking, could i drill a hole in the center and then cut a same diameter steel rod section so i can fill in the hole with it. I was thinking this would allow me to get upwards or 150-200 grains or more, and at the same time i would be adding some style. Is there any structural disadvantage to what im talking about? The metal would be glued in.
