Mofish - thanks. I like the idea of putting a pigtail screw on the back of the head. Had not thought of that. The toothpick idea is interesting as well.

I made those heads myself out of Big Hammer 'Hammerhead' leadheads. Making them was a total pain. Lead is hard to drill through. Kept breaking my drill bits doing that. It would be so much easier if they were molded. But I never got that far with it. My hope with this post is to encourage someone to do it :)
