Do-It Products

The Do-It Bass Casting Mold is a 3-cavity sinker mold that lets you produce tournament-grade bass weights at a fraction of retail cost. Whether you're fine-tuning your weight selection for a specific season, targeting particular structure, or just tired of paying top dollar for sinkers, this mold gives you the flexibility to cast 3oz, 4oz, and 5oz weights in a single setup. It's the kind of tool that pays for itself after a few casting sessions—and once you've got your own weights dialed in, you'll never go back to buying off-the-shelf.
Serious bass anglers know that weight selection can make or break a day on the water. Different depths, bottom compositions, and current conditions all demand different weights. With three cavity sizes, you can keep your arsenal stocked with exactly what you need without storing a tackle box full of sinkers you'll never use. The mold is built for durability through repeated use and designed to work with standard casting metals.
Do-It Products has been the go-to name in angler mold casting for decades. Whether you're a weekend warrior or a competitive fisherman, building your own sinkers gives you consistency, control, and serious savings over time. This 3-cavity mold is a solid entry point into lure customization and weight production.
