Application 10/973,635
10. The film method of making a bismuth fishing sinker:
comprising the steps of:
pouring a bismuth in a molten state into a fishing sinker
mold;
allowing the bismuth to solidify in the fishing sinker
mold to form a one-piece bismuth fishing sinker;
removing the one-piece solidified bismuth fishing sinker
from the fishing sinker mold;
placing a shrink wrap material around an exterior surface
of the one-piece solidified bismuth fishing sinker; and
heating the shrink wrap film material to bring the shrink
wrap film into compressive confinement of the one-piece
solidified bismuth fishing sinker to thereby inhibit the
fracturing of the bismuth fishing sinker if the bismuth fishing
sinker is impacted by an external force.
14. The method of making a fishing sinker comprising the
steps of:
pouring a frangible metal having a specific gravity of at
least 7.0 into a fishing sinker mold;
allowing the frangible metal to solidify in the fishing
sinker mold to form a fishing sinker;
removing the solidified fishing sinker from the fishing sinker
mold; and
covering the exterior surface of the solidified fishing sinker
with a layer of skin to thereby provide fracture resistance to the
frangible material.
