Master Plug Sculpting
Perhaps you are wondering why I didn’t instruct you to cast the sculpting block larger so it may be cut and divided into two or more sculpting blocks. It is the nature of Mold & Casting Compound to shrink slightly during the curing process (up to 3% depending on the amount of catalyst added). Shrinking may cause the material to warp or bend adding more time and labor to the next step: “Glass Facing”. “Glass Facing” is the term we use to describe what will be truing (making perfectly flat) and polishing the surfaces of the sculpting block. In BOOK #2, Mold Making, we will discuss casting and Glass Facing much larger blocks of Mold & Casting Compound using a much different method.
18. Your Shaping Block should now look like this: Fig. 11.
19. With #120 wet sand paper; wet the sand paper on both sided. Place the sand paper on the glass work surface. Place the sculpting block on the sand paper with firm and even downward pressure, rub (sand) the sculpting block until it has a uniform and flat surface. Do this to all six sides. Add more water to the sand paper as needed. Fig. 13.
Chapter IV (Advanced Lure Design) will demonstrate how to create a new and unique lure design by using found or “captured” shapes as a design start point.
