This 100‑pak wire form set is crafted for Do‑It Swing Tail molds, offering two insert options to cover a wide range of weights. The feel of smooth metal, the confidence of a consistent build, and the flexibility to tailor jigs to your fishing spots set this pack apart for serious DIY jig makers.

Whether you’re swapping parts between sessions or dialing in a specific lure profile, this wire form system helps you approach each casting with a fresh setup. The materials respond to light handling with a satisfying click and hold, making assembly straightforward yet precise for both seasoned pros and dedicated hobbyists.

What’s included

• 100 wire forms per pack
• Dedicated wire keeper for Swingtail jig molds
• STW155 insert compatible with heavier jigs (1/2 oz, 3/4 oz, 1 oz)
• STW130 insert compatible with lighter jigs (1/8 oz, 1/4 oz, 3/8 oz)

Two inserts designed for Swing Tail jigs

The STW130 wire insert is tuned for lighter weights, while the STW155 insert targets mid to heavier presentations. Each insert is designed to fit the Do‑It PST‑6‑A Swing Tail mold, helping you create consistent wire forms across sizes.

Specifically, use STW130 for 1/8, 1/4, and 3/8‑ounce profiles, and STW155 for 1/2, 3/4, and 1 ounce profiles. These pairings give you the ability to adjust balance, action, and profile based on your fishing conditions.

Why this matters for DIY jig work

• 100 forms per pack support multiple builds without frequent replenishment
• Wire keeper simplifies integration with Swingtail molds
• Two insert options expand your size range for flexible jig design
• Compatibility with Do‑It mold systems helps keep your workflow steady

In real‑world use, the right wire form can influence how a jig tracks through the water, how it sits when paused, and how it resists tangling on line. This pack offers a practical path to customizing jigs for different fishery environments while keeping production efficient and repeatable.

How to approach your jig builds

1. Identify target jig weight range and select the matching insert (STW130 or STW155).
2. Install the wire form into the Swing Tail mold following your standard procedure.
3. Test balance and action in controlled water to refine your setup before fishing.
