heres the orig

Guys
Im looking for a form that I can use to make my own pewter ,lead or
paste songbird feet.Does anyone know hwew if they make such an item?,
Something that I can put the wires in for the toes then fill the rest.

Turt
the carver

[It's not that hard to make a mold, Turt. You can get silicone rubber that
will handle the temperature of low-melt metals like you mention. The tricky
part may be filling the molds, as the volume of songbird feet is so small.
Surface tension will tend to prevent the metal from entering the fine
crevices of the mold cavity. A centrifugal casting machine can be adapted to
do this, or you can send your originals to someone operating a spin-casting
machine. This sort of foundry typically makes disk-shaped molds from
vulcanized rubber and fills them as they spin. To make your originals, you
might start with carvable wax, carve in the details, and then send it to a
lost-wax casting service, which will deliver metal parts that will stand up
to the molding process. ]
