Everything you need to make a Jack-in-a-Box puzzle

Here’s a fun project that you can make that will amaze your friends. When done, a tiny jack is contained inside a cube with a hole in it. How did they get in there? How was it made? The kit includes an aluminum cube to practice on and a brass cube for your finished puzzle. Producing the finished cube requires a series of drilling and boring processes explained in the step-by-step illustrated instructions that come with the kit.

Detailed Equipment List You Will Need for this Project

  • 4-Jaw Self-Centering Chuck, P/N 1075 (2.5″) or
    P/N 1076 (3.1″)
  • Chuck Adapter, P/N 37090 (included for fastening the chuck to the rotary table)
  • 3/8″ diameter end mill holder, P/N 3079
  • 1/8″ End Mill, 3/8″ Shank, P/N 7402 (2-Flute)

* NOTE: If you already own a CNC mill you do not need a rotary table. You can, instead, write a G-code sequence to accomplish the task.
