Why do you call it a fish sinker, it doesn't look like a fish.








Sorry had to do it.

Errol,
You can also buy blank molds and machine your cavity into it,

Mark:

I would not have ever thought of blank molds. We had the aluminum on hand (donated by a local company) so that is what I used.

Insert molding no less. Extra points awarded for that. In production we tried to avoid that if humanly possible because of the added labor cost, but this is a different ballgame. Labor of love, I suppose.
