Bonny Doon Narrow Synclastic Forming Stake for Swanstrom Anvil

Create smooth, rounded dimensional forms with the Bonny Doon Narrow Synclastic Forming Stake, designed specifically for the Swanstrom Anvil. Its narrow forming surfaces are ideal for jewelry and metalwork that require tighter, more focused synclastic curves than a broad forming stake can provide.

Designed for jewelers and metalsmiths working with dimensional sheet metal, this specialized stake provides a stable surface for developing rounded, concave, and convex forms. The narrower profiles are especially useful for smaller-scale jewelry, narrow components, and designs where precise control over the curvature is important.

The stake bolts securely into the Swanstrom Anvil, creating a rigid forming platform for controlled hammer work. It is part of Bonny Doon’s interchangeable Swanstrom Anvil stake system, allowing you to expand your bench with complementary anticlastic, synclastic, and combination forming stakes. The 11541901 Narrow Synclastic Stake is also included in Bonny Doon’s 11-piece Swanstrom Anvil forming stake set.

Specifications

Designed for Narrow Synclastic Forming

Synclastic forming creates dimensional shapes in which the metal curves in the same general direction along two axes.

The result can range from gently rounded surfaces to more pronounced concave or convex forms, depending on the forming surface and technique.

The narrow profiles of 11541901 make it particularly useful when you're working on smaller pieces or want to concentrate the forming action within a narrower area of the metal.

Ideal for Jewelry-Scale Metal Forming

Large forming stakes are excellent for broad dimensional work, but jewelry often requires more focused working surfaces.

The Narrow Synclastic Forming Stake is well suited to projects such as:

• Hoops
• Bangles
• Narrow bracelets
• Earrings
• Pendants
• Rounded jewelry components
• Curved sheet-metal elements
• Dimensional jewelry
• Sculptural jewelry
• Decorative metal forms

Its narrower working surfaces allow you to develop curvature in areas where a larger forming profile may be too broad.

Synclastic Forming for Hoops & Bangles

The narrow profile makes this stake particularly useful when developing rounded forms in hoops and bangles.

Rather than simply bending a strip of metal around a single axis, synclastic forming can introduce additional curvature across the surface of the workpiece, adding dimension and visual interest to the finished design.

This makes the stake a useful addition for jewelers who want to move beyond flat or simply curved bracelet and earring forms.

Stable Swanstrom Anvil Mounting

The stake is designed to bolt into the Swanstrom Anvil, giving you a secure platform for hammer forming. Bonny Doon’s Swanstrom stake system uses interchangeable forms that mount to the same anvil, allowing you to change forming surfaces as your project requires.

Secure mounting helps keep the stake stable while you concentrate on hammer placement, controlling the workpiece, and gradually developing the desired shape.

Part of the Bonny Doon Swanstrom Forming System

The Narrow Synclastic Stake is one of several specialized Bonny Doon forming stakes available for the Swanstrom Anvil.

The system includes dedicated:

• Anticlastic stakes
• Synclastic stakes
• Triple-profile stakes
• Narrow forming stakes
• Combination stakes

This modular approach lets you build a forming setup around the techniques and scale of work you use most often. Bonny Doon’s complete Swanstrom set identifies 11541901 as the Narrow Synclastic Stake and 11541902 as its Narrow Anticlastic counterpart.

Synclastic vs. Anticlastic Forming

Although the tools can look similar, synclastic and anticlastic stakes create very different forms.

Synclastic forming develops curves that move in the same general direction along two axes, producing rounded and dimensional shapes.

Anticlastic forming develops opposing curves, producing flowing or saddle-like shapes.

Choose 11541901 Narrow Synclastic for rounded dimensional forms. For narrow opposing compound curves, choose the corresponding 11541902 Narrow Anticlastic Forming Stake.

Recommended Hammer

For forming on Bonny Doon Swanstrom stakes, the Bonny Doon Urethane Hammer is an excellent companion. Bonny Doon also identifies nylon and rawhide hammers as suitable options elsewhere in this Swanstrom stake family.

These non-marring forming hammers allow controlled metal shaping while helping preserve the working surface of the stake.

Frequently Asked Questions

What is the Narrow Synclastic Forming Stake used for?
It is designed for creating rounded, dimensional forms in sheet metal, particularly when a narrower forming surface is useful for jewelry-scale work.

What types of jewelry can I make with it?
The stake is well suited to hoops, bangles, bracelets, earrings, pendants, curved jewelry components, and other dimensional metal forms.

What does “synclastic” mean?
Synclastic forming creates a surface that curves in the same general direction along two axes, producing rounded, concave, or convex dimensional forms.

Why choose a narrow synclastic stake?
A narrow forming surface gives you more focused control when working on smaller jewelry components, narrow bands, or designs where a broader stake would be too large.

Does this stake fit the Swanstrom Anvil?
Yes. It is specifically designed for the Swanstrom Anvil and is part of Bonny Doon’s interchangeable Swanstrom forming stake system.

Is the Swanstrom Anvil included?
No. This product is the forming stake. The Swanstrom Anvil is a separate part of the forming system.

What is the difference between 11541901 and 11541902?
11541901 is synclastic, designed for rounded dimensional forms. 11541902 is anticlastic, designed for opposing compound curves.

What hammer should I use?
A Bonny Doon Urethane Hammer or an appropriate nylon or rawhide forming hammer is a good choice for working with Bonny Doon forming stakes.

Where is this stake made?
The Bonny Doon Narrow Synclastic Forming Stake is made in the USA.
