Disk Puzzle
This problem consists of a base, three spindles and seven disks of different diameters. The spindles are fitted tight into holes in the base and rounded at the top so the disks will slide over freely. The seven disks are laid out on the wood with compass, and to prevent splitting the holes are all bored before the sawing is done.
The parts may receive a finish of stain and two or three coats of shellac. Polish with No. 1/2 sand-paper between each coat.
Puzzle—Place all disks on one spindle, decreasing in sizes upward. The object is to transfer the disks to one of the other spindles and to be in the same order. In doing this, never have more than one disk at a time removed from the spindles, and never place a larger disk on top of a smaller one.
