Convolution No 2 wooden ball puzzle on Stand



Convolution No 2 wooden ball puzzle on Stand

A seven piece wooden ball (koule in Czech) puzzle on a turned wooden stand.

The basis of this puzzle is the Stewart Coffin designed Convolution Cube.  Stewart made 50 from 1980 to 1983.  His design was adapted to this wonderful turned sphere version in 2007 by Jakub Dvorak.  The puzzle is rated as Demanding.  Each of the 7 pieces is made from a combination of different species and colours of wood.  The pieces are totally interlocked to make a solid sphere with a single solution.  Yes, there are no voids inside the sphere.

The bigger challenge is probably putting this puzzle back together, but in disassembly, even after you've found the first couple of pieces it still hasn't released all it's secrets.

Each puzzle piece is made from many smaller complex shaped pieces glued together; finding the correct combination that are not glued, to push or pull to take apart, may be quite difficult. 

This puzzle is hand turned in the Pelikan workshop using a selection of both European woods including  maple, walnut, birch, ash, apple, pear, cherry, oak, beech, plum, and acacia as well as some more exotic woods like mahogany, ebony, begging, wenge, walnut, American, padank, rosewood, amaranth, Bubinga, owango, jarah, meranti, and iroko.  Each piece of the puzzle is very precisely made from many smaller complex shaped pieces glued together.  The pieces are then fitted together with very fine tolerances before being put on a lathe and turned; therefore it is possible that they could be affected by very humid environments. To protect each puzzle against changing conditions they are stored and shipped in the original airtight ziplock bag they were put in in the Pelikan factory.

Ball size:  90 diameter.   Stand height: 40 mm    Colour: Random multi-colour.   Solution: A video on assembly and disassembly is supplied on DVD with the puzzle.
