My wife is very capable doing a number of things, but I would worry about the damage she would do (probably to herself) with power tools. She's very much a person who charges ahead to get to the finish point on a project, and not always taking a moment to think about the necessary steps and "what if's" of going from point A to B. We know what she can do to her fingers with a mandolin slicer, not letting her power up the table saw.
