You should consider if the cost is prohibitive to you or the
customer. Your labor to make another hollow link might exceed the
I'd make a rubber mold and make 3. In the wax hollow the bottom of
the 3, cast and assemble, leaving the link open on the bottom.
OR, take the wax, carefully slice in two, hollow out, cast 6 halves,
solder together (leave a small hole for air to escape, and assemble.
Your labor charges to the customer might exceed the extra gold to
just make them solid.
