Smart Clamp Area

I understand the purpose of the Smart Clamp, and most times I’m working with a piece of wood that is big enough to fit the carving area. But now I’m working with a smaller piece, and the carve needs to be centered as large as can be made to fit. But if I place it in the Smart Clamp, I cannot carve within that area. Is my only option to build some kind of frame that’s the same height that can hold my piece as well as fit into the Smart Clamp?

You can put a piece of material the same thickness as your stock under the clamp.
