Bill's Ball Bearing Burr (Aluminum)
|MATERIAL:||Aluminum and stainless steel|
|SIZE:||1.9" x 1.9" x 1.9"|
As longtime fans of Bill Cutler's many engaging and unique interlocking burr puzzles, we are excited to release his Ball Bearing Burr design in metal. The normal six-piece assembly is complicated by the addition of two stainless steel ball bearings which must be placed in the correct location before assembly. Once the puzzle is assembled, the bearings can move about within the internal space, requiring you to maneuver them back into the right location in order to unlock the pieces and begin disassembly. This unique concept makes it stand apart from other, more typical six-piece burrs, and if you're a fan of the archetype then this is one you will definitely want to have in your collection.
Made of machined aluminum with a sand-blasted finish, this edition has a pleasant feel in the hands, and its petite size belies the mechanical trickery within. While this version is not quite as precisely fit as our original wood version, due to allowances that had to be made for the ball bearings in conjunction with the metal manufacturing process, it does not affect the functionality in any way, and it's still just as much of a joy to solve. The puzzle ships in an assembled configuration.
Handling Metal Puzzles
I was having fun taking this apart and putting it back together without letting go of the pieces. Then I dropped it on accident… this made the puzzle much harder haha. It was one of the best puzzle rushes when I finally got it to slide back together perfectly.
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.
