Casts 



63 



Fig. 57. When securing the halves of the cast together, in larger fish, 

 place narrow strips of woven glass over the seam after the second ap- 

 plication of plastic. The other half of the mold goes over this. More 

 plastic is applied from the inside, along the strips of glass cloth— thus bind- 

 ing them to the cast. 



Fig. 58. The first step in removing the cast from the mold is to chip 



away any plastic which may have flowed over the edge of the back 



opening of the mold.
