Jig maker,
I was looking for a mold that would cast very light jigs (1/24 to 1/50) with large hooks (2/0 to #1). After much searching I finally got two pieces of 3/8" aluminum and my dremel tool out and made me one. Worked out to cast 7- 1/30 oz jigs with 1/0 hooks. Work great and wasn't too hard to make. Give it some thought.
