anybody ever used a light dimmer switch to control router speed? any electritians out there know if it would work? Seems like lower voltage would make it spin slower.

Unless you have a very low powered router a dimmer speed control wont deliver the amount of current required to run the router. Routers have high start up currents and most dimmer controls have low wattage components .

Try a mains motor controler of around 5 amps to control the router , a kit was released in silicon chip magazine oct 2002 which would do the trick

When you use light dimmer the power goes from low to high whereas motor goes from high to low. I dont think it is good for the motor. I read somwhere here that you can buy motor speed controller for $10 on sale from Harbour freight, otherwise is $20.

Buy a real router speed control like this:

Even a 5 amp dimmer is not enough. A 3hp Router would need at least a 15 amp speed control. The above unit is good to 20 amps.
