I have the professional series of Do-It molds in the 1/32 and 1/16 ounce. These are dandy molds and casting is a pure delight.
Earlier today I did a run of 600+ jigs in the teardrop mold that uses the keeper wire for the first time and it was super. I just finished a run of 1/32 ounce head, all collar-less ball heads, 250 in a size 6 sickle, and then another 250 in a size 8 sickle hook. Now I have my evening" work set out ahead of me...snapping sprues.
I found a bead pliers at a Hobby Lobby that's used to hold round beads. The notch in the jaws fit the 1/32 heads perfectly. The molds cast the heads with very little holding the sprue. I simply hold the jig head with light pressure and twist the sprue with the fingers and its off in a blink with never any clean-up needed. The molds are designed to be used with a bottom drop pot to deliver the lead, but as long as I use pure lead and make sure the mold is pre-heated well, I hand dump the lead with a ladle and have no issues whatever.
These molds are yet another excellent example of what the combining of Caney Creek and Do-It offers people. Other than the old oak mold I made about 50 years ago to get started in jig casting and a couple original Herters jig molds, all I own is the Do-It family of molds. I've tried others and they've long since taken a hike.
