Making a handicapped scrap metal centaur skeleton is real easy.
First, you take some 18th century cart wheels and an old barrel that caught your tongue a cold winters day, when you were 3 years old, and put it together on a somewhat sturdy base.
Then give it a swanky pose.
Don’t forget to use all your old car parts!
Murder a cow or something similar, and put the chewing part on top.
Throw together a couple of rebar arms.
Make a pretty flower to be held by ancient nuts and bolts.
Try on a different head, then add some really tattered hydraulic bits to simulate biceps (biceps are the key.)
Don’t forget to make a hole in the hydraulics and drain away the oil, or welding will probably end in your complete disfigurment followed by a gruesome death, compliments of burning oil and shrapnel!
Then you take off the cow’s skull and throw together some crap to make a funnier face with a light inside.
