My friend Jenna sent me some bones; I am going to see if I can turn the large vertebra into a handle for a push dagger, once I cast it in bronze. To do that, I needed a mount-point for the blade so I altered the shape with some oil-based (non sulphur) clay. From there it’s into the silicone and I’ll pour wax and do an investment mold.
The smaller vertebra is to make a sort of wingnut, so I filled the center in. When it’s cast there will be material there for drilling and tapping.
