What Is Synclastic Forming?
Synclastic forming is a metalsmithing technique used to create three-dimensional shapes in which the metal curves in the same general direction along two axes.
Think of forms such as a dome or bowl: the surface curves in two directions while maintaining an overall convex or concave shape.
This is different from anticlastic forming, where the metal develops opposing curves and often takes on a flowing or saddle-like profile.
A dedicated synclastic forming stake provides the shaped working surfaces needed to progressively develop these rounded and dimensional forms through controlled hammering.
Five Synclastic Forming Profiles
One of the key advantages of the Bonny Doon Large Synclastic Forming Stake is the number of working surfaces incorporated into one tool.
The stake provides:
- 3 synclastic forms on one end
- 2 synclastic forms on the opposite end
- 5 total forming profiles
These multiple profiles give you greater flexibility when working on projects of different sizes or developing different degrees of curvature.
Instead of relying on a single forming surface, you can choose the profile that best suits the scale and shape of your project.
Designed for Dimensional Metal Forming
Synclastic forming allows a metalsmith to transform flat sheet metal into rounded, dimensional shapes.
The five forming profiles of this Bonny Doon stake provide useful working surfaces for developing these curves while maintaining a stable and controlled setup.
Depending on your material, design, and forming technique, synclastic forming can be incorporated into projects such as:
- Dimensional jewelry
- Domed jewelry components
- Rounded metal forms
- Cuffs and bracelets
- Pendants
- Sculptural jewelry
- Decorative metalwork
- Vessel forms
- Curved sheet-metal components
- Small-scale metal sculpture
Hexagonal Center for Secure Vise Mounting
The Bonny Doon Large Synclastic Forming Stake features a hexagonal center section designed to clamp securely in a bench vise.
The flat surfaces of the hexagonal profile give the vise jaws positive gripping surfaces, helping prevent the stake from rotating or shifting while you work.
This design allows the forming stake to integrate into an existing metalsmithing bench without requiring a proprietary anvil system.
Secure mounting is particularly important during hammer forming because unwanted movement can make it more difficult to control the workpiece and develop consistent shapes.
Compatible with Most Bench Vises
The Large Synclastic Forming Stake is designed to work with most bench vises, making it a versatile addition to an existing jewelry or metalsmithing workspace.
Clamp the hexagonal center securely in a suitable vise to create a stable working position for forming.
The vise and workbench should always be substantial enough for the type and force of the forming work being performed.
Pair with the Bonny Doon Vertical Vise
For a purpose-built metal-forming setup, pair the Large Synclastic Forming Stake with the Bonny Doon Vertical Vise.
The Bonny Doon Vertical Vise is designed specifically for securely holding forming stakes and mandrels during hammering and metal-forming operations.
Together, the Vertical Vise and Large Synclastic Forming Stake create a dedicated workstation for controlled dimensional forming.
For metalsmiths who perform forming work regularly, this pairing provides a particularly logical bench setup.
CNC-Milled for Rigidity & Reduced Flex
The Bonny Doon Large Synclastic Forming Stake is precision CNC-milled for superior rigidity and reduced flex.
Stability matters during hammer forming.
If a forming stake moves or flexes excessively, some of the energy from each hammer blow is absorbed by the movement of the tool rather than being directed into the workpiece.
A rigid forming stake provides a more predictable working surface, helping you concentrate on:
- Hammer placement
- Metal movement
- Developing curvature
- Maintaining symmetry
- Refining the shape
- Controlling the finished form

Synclastic vs. Anticlastic Forming
Understanding the difference between synclastic and anticlastic forming can help you select the right Bonny Doon stake for your work.
Synclastic Forming
In a synclastic form, the metal curves in the same general direction along two axes.
Typical shapes include:
- Domes
- Bowl-like forms
- Rounded surfaces
- Convex forms
- Concave forms
Anticlastic Forming
In an anticlastic form, the metal curves in opposing directions along two axes.
This creates shapes with flowing or saddle-like profiles.
Which Stake Should You Choose?
Choose the Large Synclastic Forming Stake when your work primarily requires rounded, domed, concave, convex, or similar dimensional forms.
Choose an Anticlastic Forming Stake when you want to develop opposing curves and saddle-like forms.
If your work regularly incorporates both techniques, Bonny Doon Combo Stakes provide both anticlastic and synclastic forming surfaces.
Why Choose Multiple Forming Profiles?
Different projects require different curves.
A single forming profile can limit your options, particularly if you regularly work with jewelry and metal objects of different sizes.
The five forming profiles on the Bonny Doon Large Synclastic Stake give you multiple working surfaces within one tool.
This makes it easier to:
- Select a profile appropriate to the project
- Experiment with different curves
- Work on different sizes of metal forms
- Progressively develop dimensional shapes
- Reduce the need for multiple individual forming stakes

How many forming profiles does the stake have?
The stake has five synclastic forming profiles—three on one end and two on the opposite end.
What is synclastic forming?
Synclastic forming creates a shape in which the metal curves in the same general direction along two axes, producing forms such as domes, bowls, and other rounded three-dimensional surfaces.
What is the difference between synclastic and anticlastic forming?
Synclastic forms curve in the same general direction along two axes. Anticlastic forms curve in opposing directions, creating flowing or saddle-like shapes.
How does the stake mount?
The stake has a hexagonal center section that clamps securely in a bench vise.
Will it fit a standard bench vise?
The Bonny Doon Large Synclastic Forming Stake is designed to be compatible with most bench vises.
Can I use it with the Bonny Doon Vertical Vise?
Yes. The Large Synclastic Forming Stake can be used with the Bonny Doon Vertical Vise, creating a stable, purpose-built forming station.
Why does the stake have a hexagonal center?
