Acquire a human skeleton and a skeleton horse. For this prop, we used two store bought props and combined them together to make a sideshow act.
We unscrewed the skeleton just above the pelvis, and removed the horse neck and head from the horse skeleton. Then, we joined the two pieces by zip tying them together.
Step 3 (Optional):
To add more to our centaur, we used a wig that we had to give him some hair, and to add to his side show act.
We have a tutorial for a Circus Wagon, which can be used with the Centaur.
