You have seen this type of device in the movies now build your own. Average assembly time can be up to 7 hours. I know that it is long but the process is rather satisfying upon completion.
Included is an engineered build plan along with the cardboard shapes that you must cut out and assemble.
You will need to supply the cutting tools and glue. Recommended is super-glue (cyano type), glue-stick and hobby knife for cutting and assembly.
Step 1: Download and print.
The cutting of the shapes is best accomplished with a sharp x-acto type knife but scisors will do in a pinch.
You will need to print 5 of the 26Wheel file, 1 each of the remaining. The assembly7 file is meant to be printed on standard copy paper.
Step 2: Cut the shapes from the print-outs.
All solid lines need to be cut out from the printouts while the light or dotted lines ar there to represent folds. The included PDFs show the assembly steps.
Each outer code ring has 26 flat sections for lettering later.
You will need to assemble 9 code rings for a 5 letter combination.
Precision cutting is key here so take care in this step. The better your cuts, the better your finished item will look.
The first step is to assemble the code rings as shown in the pictures. The clue of choice here is Cyano type or crazy glue if you prefer. This is a rapid setting type glue and works exceptionally well on paper or cardboard.
Do not worry about any discolouration of the paper as this will be addressed later.
Step 3: Make the end caps
