This very special piece of puzzle furniture consists of eight different notchable six piece burrs.
David Bruce designed this puzzle in 1985 and although he designed it by hand he did later have a computer check it’s assembly to ensure it was unique. He called the puzzle “Lost Day” because he thought if it takes an hour to put each piece in it’s correct place it would take 24 hours to assemble all the pieces.... we think this is being VERY optomistic!
The goal of the design was to make sure each of the eight corners was a different burr and that all were notchable burrs with no key piece.
The puzzle is presented as an occasional table but may be purchased with or without the 500mm round glass top (with polished edge). Glass is difficult to ship and you may be able to purchase the glass locally for less than we can supply and ship to you. Already included in the shopping cart price is an additional cost of glass Aust$30.00. There will also be and additional freight charge when purchasing with glass top.
The puzzle occassional table is available crafted from Western Australian Jarrah and is shipped completed WITH 500mm round glass top.
The puzzle is to assemble to 12 piece burr representing the letters T L & N on three sides.
Junichi Yananose created this puzzle in 1991 but to date it has not been commercially manufactured. Although it is a 4x4x4 burr the 4 pieces on each side are not symetrical, rather making four different shapes in the form of the letters T L and N. As well as being very difficult to assemble this puzzle can also be relatively difficult to disassemble if you are not holding the puzzle just right.
This puzzle is crafted from the very dense and heavy timber called Cooktown Ironwood which is grown only across the very north of Australia in a thin band from Cooktown to Darwin. Size: 150mm x 150mm x 150mm.
NOTE: Original selling price in USD was 78.30. In April 2008 one of these puzzles sold at Baxterweb Puzzle Auctions, Featuring the John Ergatoudis Collection Phase 12 for USD 160.00.
Leonid Mochalov, a Russian mathematics teacher, (website: www.puzzlemochalov.narod.ru) first published a book of puzzles in 1980 and updated it in 2000 releasing “400 Puzzles & Tricks” (very loosely translated by a friend who is not actually Russian). This puzzle is taken from that book and we think Leonid's name for the puzzle translates as "Knot Out Of Flat Element". It is an eleven piece burr utilising flat rectangular pieces. Because it has a solid locking piece it is not a very difficult puzzle, however it is quite an unusual burr design.
This puzzle is crafted from Satin Sycamore grown in North Queensland. Size: 120mm x 120mm x 120mm
