Having been involved in parts of this where the tools being motorized allowed for me/anyone to make more parts, faster, and with quite a bit less wear and tear on a body. So I would HAVE to add from more than the beer/meat powered tools. I have them in all of the above categories, plus quite a few others. Blended woodworkers burn calories, and electrons. 

Retired, and just tinkering, for lack of a better word, do I need them, Hail no. Would I give them up before the date of the final sale, again Hail no. :-)
