Cipher Disk Decoder for Escape Rooms

After processing the job, glue the center hub of the number disk to the letter disk, using the score lines as alignment guides. Next, place the outer ring of the number disk onto the hub, then glue the cover disk on top. You’ll likely need to use a spacer to ensure the outer ring can spin freely—I used a small wafer of paper, which worked perfectly. Lastly, apply a couple of coats of clearcoat.
