I know they make glue from horse hoofs ect.,why not deer hoof, or maybe they or some of you do.Just A thought I had for using as hide glue. Would much app. any and all thoughts.
I bet you could grind it into a powder by filing it with a rasp, then add a little water and boil it. I imagine it would make a fine glue.
Try it and let us know how it works out, but I bet it stinks? You might want to do it outside.
