5x5x5 Professor Cubes / Rubik Wahn
4.2, 7cm / 1.7, 2.8 inch edges
This was made in 1996 from two of the original 5x5x5 Rubik's Wahn / Professor Cubes that Christoph Bandelow was selling in the nineties.
If I was to make it today I would either use V-Cubes or Eastsheen Cubes. With them it would simply be a case of cutting and gluing. With the Professor Cubes though it was far more time consuming and quite frustrating to make. That is because the Professor Cube (and 4x4x4 Master Cube) has a rather unusual characteristic. When they are being turned the cubies will individually undulate very slightly. It's almost like a tiny ripple going across the puzzle. If this undulation is prevented by fixing some of the cubies together the puzzle becomes very stiff and almost unusable. That is precisely what happens when making a Siamese puzzle. I therefore had to spend several hours scraping and sanding parts of the mechanism to create a bit of space to make up for the lack of undulation.
Naturally for colours I have used the same Rubik's
Cube style that the original puzzles came with. The puzzle is fully functional though some people bizarrely expect the horizontal layers (looking at the second photo) to rotate.
I have made a total of seven Siamese puzzles. They are- Siamese Cubes, Siamese Skewbs, Siamese 5x5x5s, Triamese 5x5x5s, Siamese 2x2x2 Triplets, Siamese 6x6x6 V-Cubes (black and white) and White Micro Siamese Cubes.
Sometimes I sell a version of this puzzle made from Eastsheen Cubes. For availability and prices see my puzzle shop page- Puzzles by Tony Fisher.
