Do-It Worm Sinker Mold Asst 9cavity
The Do-It Worm Sinker Mold Asst 9cavity is a multi-cavity sinker mold designed for anglers who want to cast their own sliding sinkers for plastic worm presentations. This 9-cavity setup lets you produce multiple sinkers in a single pour, making it an efficient choice if you fish worms regularly or want to experiment with different weights and rigging styles without buying pre-made singles.
Sliding sinkers are workhorse weights in weed-heavy water, where they let your plastic worm slip through vegetation with minimal snagging or tearing. The streamlined shape Do-It built into these cavities aids casting and retrieval in dense cover, and the small-hole design accommodates standard monofilament line. Because you're pouring your own, you control the final weight—useful for tuning presentations to specific depths, cover types, or current conditions.
This is a mold, not finished sinkers, so you'll need lead or another casting alloy, a heat source, and basic casting equipment. If you're new to sinker casting, the learning curve is gentle: Do-It molds are reliable and straightforward. Once you've poured a batch, you'll have a supply on hand and know exactly what you're fishing—no guessing about unknown manufacturer specs or grabbing whatever's loose in a tackle box.

Frequently Asked Questions
What do I need to cast sinkers with this mold?
You'll need lead or another suitable casting alloy, a heat source (such as a sinker pot), and a way to safely pour molten metal. The mold itself is just the cavity tool—the finished sinkers depend on your casting setup and material choice.
Will these sinkers work in weedy water?
Yes. The sliding sinker design and streamlined shape are specifically intended for weed-bed fishing, where they help prevent snagging and tearing of plastic worms during retrieval.
What line weight works with the holes in these sinkers?
The cavities are designed with small holes sized for monofilament line, which is the standard choice for sliding sinker rigging.
How many sinkers will one pour make?
The mold has 9 cavities, so one complete pour will yield 9 sinkers. The final weight per sinker depends on the alloy you use and how full you pour each cavity.
