Here’s a fun project that you can make within an hour or two that will amaze your friends. When done, a tiny cube with a hole through it is contained inside another cube with a hole in it. Both of those are inside a third 3/4″ 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 four pages of step-by-step illustrated instructions that come with the kit.
The kit includes both an aluminum and a brass billet of 3/4″ square stock cut to slightly over 3/4″ long ready for you to make this interesting puzzle on your Sherline lathe and mill. (It can also be made using just the lathe.) Included are a 3.1″ 4-Jaw self-centering chuck, 3/8″ tool post, two boring tools (one is custom ground as an undercut tool), a 1/8″ drill, a #2 center drill and a key ring.
The improper use of machine tools and their accessories can result in serious injury. Before using this tool, thoroughly read the instructions and make sure you understand its proper and safe use.
Always wear safety glasses when operating machine tools.
