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
