These will be part of a very cool, very macob staff. Once I figure out how to join them. And I know it looks cool but the feline skull is from an old aquarium.
Very cool! You could always drill a hole through every bone, and run a thin metal pole through it. If it's going to be curved then I'm not quite sure how that'd work, unless you can bend the pole somehow. Lol, I'm not an expert at inventing/creating things.
Aluminum Tubing or thick wire may give enough strength without the weight also.
Though it hassn't been mounted you can see the finnished product here...[link]
