I promised myself that if I ever did this again, I would take pics and share. I had a noise on my bandsaw that I traced to the motor centrifugal switch; easy fix. My cyclone started making a similar noise and based on my previous experience a few years ago, I went right to the switch. The noise is harmless; it is caused by the reverse-giggle-bearing rubbing on the doo-funny. In technical terms that means the plastic ring that pushes the spring-steel loop that opens the switch rubs enough to start an oscillation that creates a sound somewhere between a scrape and a squeal.Unplug your tool and remove the motor fan cap (three screws on mine)I mark the fan position with a felt pen and loosen the retaining screw. Remove the fan.Remove the clutch cover (two screws on mine)I mark the height and screw position before I remove the centrifugal assembly.Put some fine sandpaper on something flat and buff the flat surface of the pressure ring. Here I use 600 grit on my workbench top.Rub some graphite into the flat face of the ring and re-assemble.My bandsaw hasn't made a peep since I did this. Time will tell for the cyclone.
