This puzzle was designed by Robert E. Sandfield and crafted by Perry McDaniel. It is a good example of an impossible dovetail joint. This is a type of impossible object, so called because there appears to be no way to separate a dovetail joint which consists of a dovetail on all four sides. To make the puzzle harder, a magnetic lock is inside and it has to be released before the two parts of the puzzle can be separated. Complete with instructions, part of which say ‘Take care not to lose the steel locking pin. It has been trained to take every opportunity to roll under heavy, immovable objects’. The puzzle was purchased from H & R Magic Books at the Magic Collectors’ Association Weekend, Schaumburg, 1996. It came in a blue draw string bag with ‘Sandfield Joint Puzzle 2’ on a piece of wood attached to the string. Because the idea of this puzzle is to take it apart, people interested in mechanical puzzles also classify this as a Take Apart Puzzle.

This is an example of an impossible object, because it is so hard to envisage how these balls within balls could be turned from one piece of wood. The puzzle is therefore ‘how is it made?’ The object is shown resting on a separate stand. This was a gift from skilled woodturner David Springett. David explains how such a piece can be made in his book ‘Woodturning Wizardry’. The book was first published in 1993 by Guild of Master Craftsman Publications Ltd, Lewes, East Sussex.

The clear plastic disk swivels round on the key ring. The puzzle is to remove the coin that is trapped inside the disk by a number of ball bearings. Every time you tap the puzzle so that the coin starts to drop out, the ball bearings roll down and stop the coin from going any further. The sure way of solving the puzzle requires a flick of your finger – but you need to know where to flick. This is a well designed and manufactured puzzle.
The wooden boat has a clear celluloid cover and inside are two ball bearings. The puzzle is to get a ball into the small hole at each end of the puzzle. Unless you know the secret, it’s frustrating. Getting the first ball in is easy – you simply tilt the boat sideways. But when you tilt the puzzle back to coax the second ball into the second hole, the first ball falls out. This is a puzzle that needs ingenuity rather than lots of jiggling. The puzzle has been popular over the decades and has often been used as a commercial give away.
The puzzle is to open the match case.The metal box has a corrugated striker on one end. On the lid are the words: JOHNNIE WALKER. On base are the words: OPEN THIS BOX AND I’LL STAND YOU A JOHNNIE WALKER. The side of the case has on it: PAT24.846/10. This is an entertaining, seldom seen puzzle.
