grip screw seized

[sheepherder]

Another option is to clamp it securely to a drill or mill table; run the quill down (with a screwdriver bit in the chuck) into the screw, lock it, and then turn the quill manually...

I have done this occasionally, obviously the trick is to secure it so it doesn't move and doesn't mar the finish or scratch the wood...This works quite well on recessed screws...
