StewMac Acoustic Guitar Side Bending System
There are only a few tools that take center stage in your shop and redefine how you work. This is one of those tools. Completely redesigned with input from Charles Fox, the original inventor of the "Fox" bender, we've created the ultimate system for bending acoustic guitar sides.
We know there are other systems out there, and we've used them all. Each had its own challenges, quirks, and high learning curve—we fixed ALL the problems they have.
We set out with one goal in mind: making the most versatile bending system in the world. We spent over 10 years painstakingly refining prototypes with Charles Fox, rethinking and improving every aspect of the original design. We wanted to make bending consistent, predictable, and approachable for every builder.

Why use a bending machine?
While hot pipe bending has served luthiers well for centuries, it often causes uneven lumps and bumps—requiring significant work to get a smooth profile. And highly figured woods are more susceptible to damage and cracking when bending on a hot pipe. Using a bender is a guaranteed investment in the quality and consistency of your builds, your sides come out perfectly bent with no spring back.
Consistent bends—every time
Let's face it, bending sides the old fashioned way takes a lot of practice and skill to get smooth curves and a perfect fit. And even when you have the skill to do it, it's not a fast process. With a professional side bender you get constant, repeatable results build after build—and it's much more beginner friendly than a hot pipe.
What makes the StewMac Acoustic Guitar Side Bending System special?
Open-sided design: Unlike other benders, our bender's open-sided design gives you full access to load your side, no more clumsy maneuvering and hoping your straps and sides stay aligned. This makes it so easy to get your waist bent exactly where you want with no surprises.
Adjustable waist clamp: Our game-changing waist clamp instantly adjusts to any shape, providing perfect pressure exactly where you need it. There's no need for additional jigs when you want to build something new. You can even use your own custom forms with no modification.
Precise temperature control: Our custom-built temperature controller and heating blanket have pinpoint temperature precision. You get real-time monitoring of the temperature of your side and the blanket—you know exactly when to start and finish your bend for perfect, no surprise results. This is so much better than the old meat thermometer method!
Build different body sizes on the same bender: our one Bender seamlessly adapts to different shapes with instantly swappable body forms. With 8 different interchangeable bending forms (Dreadnought, OM, 000, J-45, and cutaway versions of each) there's nothing holding you back. Want to build a different shape? Just swap in the new forms. You can even use your custom designs on the same Side Bender!
Built like a tank: Crafted from extruded aluminum, 13-ply Baltic Birch and featuring an industrial ACME screw press, this bender has zero give and flex. Every part of this bender is professional quality and rigorously tested to perform flawlessly. We made each part to withstand all the heat, pressure, and steam you can throw at it.
