Do-It Bass Casting Mold 3/8, 5/8oz

The Do-It Bass Casting Mold 3/8, 5/8oz is a sinker mold designed for anglers who want to pour their own custom bass lures and terminal tackle. This mold casts sinkers in two popular weights—3/8 oz and 5/8 oz—giving you flexibility to match different water conditions, retrieve speeds, and cover types. Whether you're building swimbaits, drop-shot rigs, or Carolina-rig sinkers, casting your own lets you fine-tune your lure lineup without the markup of pre-made versions. Do-It Products molds are a reliable choice for serious DIY lure builders who want to control quality and inventory.

The mold features a molded-in swivel, eliminating the twist and line-management headaches that come with traditional sinkers. This integrated swivel keeps your lure riding true and reduces the likelihood of line twist during prolonged casting or fast retrieves—especially important when you're working deeper structure or fishing heavy cover where lure rotation and hang-ups matter. For bass anglers running multiple presentations across a season, having the ability to cast matched weights and designs in your go-to patterns is a real advantage.

Using a sinker mold is straightforward: you'll need lead (or lead-free alternative), a heat source, and a way to secure the mold safely. Do-It molds are engineered for durability through repeated casting cycles, making this a one-time investment that pays off over years of custom lure production. If you're already into tackle customization or thinking about getting into it, this mold opens up your options for bass-specific weights and designs.

Frequently Asked Questions

What weights does this mold cast?

This mold produces sinkers in two sizes: 3/8 oz and 5/8 oz. Both weights have a molded-in swivel.

What do I need to use this mold?

You'll need melted lead (or a lead-free alternative), a secure way to hold the mold, and a heat source to melt the casting material. Do-It does not supply lead or casting equipment with the mold.

Is the swivel included in the casting, or do I add it separately?

The swivel is molded directly into the sinker during casting—it's not a separate insert. This is one of the key features of this mold design.

Can I use this mold for saltwater fishing or just freshwater bass?

The mold itself will work with any casting material you choose to use. The 3/8 oz and 5/8 oz weights are commonly used in bass fishing, but you can apply them to other freshwater or light saltwater applications based on your needs.
