🇺🇸 C-clamp (also known as a G-clamp) that has been modified with magnetic pads to protect the surface of the workpiece being clamped.

Function and Modification
This image shows a clever woodworking tip:

Protecting the Workpiece: A plywood pad is used as a barrier between the steel clamp jaws and the workpiece to prevent the surface from being dented or damaged due to strong pressure.

Use of Magnets: A small magnet is embedded into the plywood block. This allows the wooden pad to attach magnetically to the metal surface of the clamp jaw, so it does not easily fall off when the clamp position is adjusted.

Magnetic jaw pads on a modified C-clamp demonstrate a simple yet highly functional surface-protection system—combining load distribution through plywood with magnetic retention for quick repositioning and zero slip.

In your professional experience, does this magnetic solution provide sufficient holding strength under high clamping pressure, or would you refine it further with a recessed housing or higher-grade magnet for heavy-duty applications?
