  Introduction  
  Making the tablet from stone will be the ultimate prop but there are a lot of
problems to face
Engraving is not an easy job and the weight of the prop wil make it difficult to handle
I make the prop only for display purposes and will have a weight of about 1 Kg
The prop is not finished yet but i wanted to share the process and get you started
     
  Materials  
  Hi density PU (polyurethane) foam ( 50 x 150 x 2,5 cm)
  Carbon paper  
  Dremel tool or engraving tools  
  Solvent based transparent groundcoat  
  Waterbased paint  
  Brushes  
  Sandpaper  
  Glue

The template will be 6 pages
when printed on A4 size paper.

Glue together in the following
order :

1 2 3
4 5 6

     
  Because i traced the image with
carbon paper i had to prepare
the surface of the foam.
Otherwise the ink will not adhere.
Spray a thin layer of gorundcoat
on the surface.
The solvent will dissolve the PU
slightly and give a rough surface.

I had to cut the foam i used in half
to get the actual size,thickness will
be adjusted by glueing to parts on
top of each other

Let dry and fasten the template
on the foam.
Using a few screws at the border
proved to be the easiest way.

Use carbon paper to trace the image.

     
  Traced image
     
 

Start engraving the image.

The depth can be varied to apply to your personal taste.

   
  Use some waterbased paint on a damp cloth and wash the surface to test the engraving depth on a scrap piece
