Fig. 392 shows a variation of the Chinese cross, which is perhaps the most fascinating of all woodwork puzzles. Take six pieces of hardwood ( Fig. 394 ) and accurately plane and saw them so that each piece will measure 4 ins. by 1 in. by 1 in. Bearing in mind that all the cuts are multiples of 1⁄2 in., set out, saw and chisel five of the pieces to agree with the sketches 1, 1A, 2, 2A and 3. Leave the key piece intact. The puzzle is of course to fit all the six pieces together so as to form the Chinese cross or block given at Fig. 392 . As a clue to the method of assembly we give another sketch ( Fig. 393 ) showing four of the pieces fixed together. The reader can, if he so desires, make the puzzle to a smaller scale by using six pieces of wood each measuring 2 ins. long by 1⁄2 in. by 1⁄2 in.
