I'm taking a woodworking class right now in Chicago. I'd classify myself as an intermediate-level woodworker, but am taking this class mostly to learn something about hand tools. While everything we have done to this point has been with mallet, chisel, and saw, we discuss other aspects of woodworking, including power tools. The instructor (a gentleman with an extensive woodworking background starting as a German apprentice 30 or more years ago) commented on his dislike for variable-speed routers. His opinion is that because the variable-speed works by reducing the voltage to the motor, that frequent running of the router at a speed other than the full speed has the long-term effect of damaging the motor, at least with the class of router they have, which is a P-C probably not dissimilar to my 8529. I'd like to know what informed wreck'ers think of that.
