rheostat with router/ effective?
I'm thinking of getting an aftermarket variable speed thing for an
older bosch 3 1/4 horse router [1611]. do they work well? do they go from zero? do you guess the rpm by sound? I'm doing this so i can safely run panel bits in a table. any info will help...thanks. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

It'll slow a universal motor down all right, and you could get a tach setup off of the number of commutator bars and a brush. But why bother? |

A resistive type of voltage reducer (rheostat) is the wrong thing to buy
because it will not only reduce the speed of the router but the power too. A speed controller that is designed for controlling the speed of routers and other brush type motors sends full voltage to the motor to maintain full power, but it does so in short pulses that vary in width as the speed setting is changed. These controllers will allow you to set a lower speed, but still have the power that you need. The knob is usually marked 0-100 meaning % of full speed. This is more than close enough to get the speed that you need for running panel raising bits. These controllers work great from about 25% to 100% but are significantly less effective at controlling speed between 0% and about 25%. -- Charley wrote in message ...
