Put it in reverse for simple frame finishing
By reversing the jaws of a one-handed clamp (making it a spreader), you can use the clamp to hold a trivet or picture frame while you apply a finish with your other hand. Expand the jaws into the frame's rabbet, where missing finish won't show. Then, insert a hook through the hole in the end of the clamp bar and hang the hook from a wire loop for drying. I leave off the clamp pads for better jaw bite on the thin rabbet edges.
