I was going to make some and just bent the hooves at the joint and let them dry (About 8 sets). The following year I cut them to size on a chop box(mitre saw).The next year I threw them out since I had no time or place to hang them when I was done. Figured I can always get more. By the way there was no hair slipage or strong odor I imagine if I filled the marrow pat with a wooden dowel or epoxy I would have had something to screw the backboard too. I've got the instructions somewhere.
