I have a rattle in my cabinet saw that I can't track down. It is definitely within the cabinet and it "rings" like a sheet metal (not cast iron) part that needs to be tightened. With the saw running without a blade I tried to carefully touch each possible part to see if I could identify the loose part by dampening the vibration. No luck there. Is it possible that there is a loose part within the motor assembly? (it's not the capacitor covers, that was easy to check). Any other idea on what it could be or a mothod of diagnosis?
