Tail Weights with Center Hole

[Charleston]

Try this; Make 1/2 round in one side of the mold. Align that to a flat raised area on the opposing mold half. When you demold the lead you have a half round piece with a flat key way down the center. Put two pices in the plug so the keyways make the through hole.

This is much easier than trying to keep wire aligned on centet in the mold.
