In various woodworking catalogs you will see a device that allows you to vary the speed of your router by turning a dial. I assume it is like a rheostat on a light fixture. I also assume that lower speed also means lower power.
I have never seen a device like this promoted for other tools. Could this device, marketed for routers, also be used on a drill press or a lathe? On the drill press, it would be nice to make a change in speeds without the hassle of moving the belts and, on the drill press, a reduction in power may be acceptable in some situations. On my lathe my lowest possible speed is 500 rpm. When turning a really big piece (16” in diameter) I would like a slower speed. I realize the reduction in power would force me to go slower, but it would make it possible to turn some big turnings.
Of course, the last thing I want to do is damage my motors.
Any thoughts and advice are welcomed.
