Take-Apart - The Cage and Ball

The Cage and Ball
Craftsman:John Berkeley
Category:Take-Apart
Material:Yew & Ebony
Pieces:3

The objective is to remove the ball from the cage.
 
One of the pillars can be rotated to a point where it will fall into a notched recess. This allows it to slip from the hole in the upper section. The ball can then be removed.
