A professor who specializes in Sculpture has the greatest potential of creating the necessary artifacts for the blind student.   Following are the directions for an Art professor to use for constructing the necessary artifact:

Producing a relief image of the bell curve

• Using this method to transfer the image of a bell curve onto a wood board for rendering a relief image will require several supplies.

Before beginning this project you will need the following items

• Tracing paper or carbon paper

• Particle board or most any 8inch by 11 inch (or larger) wood board at a thickness of ½ inch or thicker
• Router
• Pencil
• Scanner/Printer
• Polyurethane
• Paint brush
• Sand paper

Steps

1.  After finding the image that you want to transfer the image can be scanned and printed to a size of your choosing 

2.  You can either trace over this image with tracing paper, or simply place a sheet of carbon paper between the printed image and the board and use a pencil to rub the transfer ink onto the board  

3.  If you choose to use the tracing paper, you will have the additional step flipping the tracing paper back over after the first tracing to transfer the image accurately.  

4.  The board that you are transferring onto should be free of knots and have a smooth surface.  Particle board or MDF (medium density fiberboard) may produce better results than a pine board since the particle board has no wood grain and will yield a smoother surface. In either case, you should avoid chip board and plywood due to their rough surfaces.  

5.  After the image is transferred, you will need to use a router with a ¼ inch diameter bit (or larger) set a depth of ¼ inch to cut away the image you have transferred onto the board. A little light sanding and a brushed on coat of polyurethane will help protect your fingers from the wood and the wood from your fingers.
