Heating Element Control

[cwood]

What about a Router Speed Controller....? I believe they are just HD rheostats, not the preferred variac.However, because they are designed to regulates the speed of a router motor, probably up to 3 HP at say 10-15 amps, wouldn't that do just as well...? Easy to plug into wall, and plug heating element into Speed controller....??? Not too pricey either..... Anybody ever done that??? Feed back............??

Thanks,
