You need an infinitely variable gearbox. In the last 15 years this problem has been solved in two different ways, both of them robust, reliable and satisfactory. One which I read about in Popular Mechanics magazine more than 10 years ago, converts rotary motion to to-and-fro motion, where the infinitely variable gear change is applied, then back to rotary motion. The other, more recent, uses cone pulleys but the belt, instead of being rubber with a triangular cross section like in some garden tools, is made of metal segments, and it is used in a production car; that's how much power it can transmit.

you are right about them being used on lathes. Both General and Rockwell had wood working lathes with the system you are asking about and they had a lever to change the speed while the lathe was running. good systems, I used them both back in the seventies. good luck.
