  2. Modify the spindle of the CNC router with a nail that will be used to make braille character impressions on different materials like paper, plastic, etc.

  This includes,

  - sourcing a nail of suitable size and diameter that fits at the bottom end of the CNC router spindle.

  - cutting the nail to appropriate length using a metal cutter, and making its tip blunt using a Bench grinder for grinding and buffing.

  - Attaching the needle to the end of the CNC router spindle.

  We used a drilling machine nail of diameter 3 mm and cut it to a length of 45 mm.

  3. Fix the material on which you wish to print braille on an MDF wood sheet with a tape and place it under the nail.

  We’ve used a 180 GSM drawing paper of dimensions 200 X 200 mm.
