The 66 piece cube is a difficult to take apart excellent design by Bill Cutler.   A tricky sequence of moves are needed before the key piece will come out.   It is made from .730” Walnut,  Cherry and Maple square sticks.  It is 4 3/8” x 4 3/8” x 4 3/8”. 

Made by Jerry McFarland.

I started making these again in 2008 and they will be sold by Bill Cutler.
