Also a lifelong woodworker Ron Iacobelli believed there had to be a way to expand the gripping capability of an ordinary vise to make it better suited for holding odd-shaped parts. At the time, there was no good solution.

“When you’re woodworking, you need to clamp things like pediments, spindles or tapered spindles and legs that don’t have parallel faces … before Gyrojaw, I wouldn’t have known how to put these sorts of parts in a typical vise. I’d immediately try to think of another way to do it,” Ron recalls. But once he landed on the concept of a pivoting vise face, it seemed like it could open up a whole new way to approach clamping.

The idea for Gyrojaw came to Ron in the mid-1990s while working as a modelmaker for Michigan’s automotive industry.

Ron joined forces with his brother Mike, a tool designer with a CAD background, who worked out other details, such as how to create a cost-effective injection mold. Mike experimented with various ribbing solutions to make Gyrojaw sufficiently strong but still lightweight. He also needed to determine the optimal size for Gyrojaw, so that it can be pivoted to a range of different positions and still work inside of most vise sizes.

The Gyrojaw is used to secure a wedge in a standard vise.

With countless challenges, modifications and revisions — and 15 years since the idea came to light, Gyrojaw is now a reality and gaining in popularity as a way to give your traditional vise the versatility of a pivoting vise face, but one that’s faster to work with and less expensive as well.

In a nutshell, Gyrojaw is a pyramid-shaped fixture that fits against a jaw of a metal vise. A carriage bolt is embedded into one end, and its curved head allows the Gyrojaw to be pivoted to many angles and then clamped tightly against a workpiece. Friction and pressure between Gyrojaw and the vise surface is what holds it in place. The opposite end basically amounts to an articulating vise face.

Ron and his brother Mike invested time and money in Gyrojaw so you can save time and money. Whether you are a weekend woodworker, a professional carver, in the construction business or just do home repair projects around the house, Gyrojaw is a simple but elegant solution to “Clamp the (previously) Un-Clampable!”

Gyrojaw can be used for angled jobs that require multiple clamps.
