HOW TO MAKE SPINNERBAIT HEADS
Ladle: How to Make Spinnerbait Heads Best results are obtained by pouring spinnerbait and buzzbait molds with a ladle. A bottom pour melter may not have enough flow volume to fill the cavity before the lead cools. This results in unfilled and wavy heads. The wire shaft often gets in the way of the melter nozzle causing difficulty in getting  lead into the cavity.
Spinnerbait Hooks: How to Make Spinnerbait Heads Use a small eye spinnerbait hook like the Eagle Claw 253 and Mustad 32606.
How to Make Spinnerbait Heads Try this technique using diagonal cutters to crimp the wire eye tightly shut.
Have a problem getting the collar to fill on your spinnerbait and buzzbait molds?
After the mold is closed on the inserts, look into the cavity gate and make sure the shaft, hook eye connection is centered in the body of the head. It can slip down and block the collar making it impossible for the collar to fill. After the inserts are in position, we bend the wire shaft a little bit to hold the hook and shaft in place while pouring.
