Bill's Ball bearing burr is one of my all-time favorite interlocking puzzles. The normal six-piece assembly is further complicated by the addition of two stainless ball bearings which must be placed in the correct location before assembly. The bearings are then released once the puzzle is assembled, and the solver must figure out how to maneuver them in order to disassemble the puzzle. A very unique concept and a must-have for your collection!
Fit and finish is excellent with this puzzle, which was realized with .88" stock to precisely accommodate the bearings. All tolerances are within several thousandths of an inch, with decorative end-grain bevels on the dense Jatoba used.

Where did those ball bearings come from!? And where do they go now? The burr itself might not puzzle too many puzzlers, but those ball bearings sure throw a wrench in your plans. Great puzzle, and a very satisfying solve once you get there.
This one is love at first touch. The balls provide such nice locking of the whole thing. Perfect fit of all pieces and a good level of difficulty.
After assembly I tried now to open this tricky burr, without success. Is is not only made very fine, but also originally - including hidden two balls, which are desturbing us to solve the task and reassemble the burr. Congratulation, Eric, a superb idea to remake this puzzle, suddenly my burr opened, moving some pieces, and it was not clear how, something like magic ?
