Started cutting thick item and Dw 788 started to really rattle. Did the bit under the switch but did not see any rubbing. Turned the rod but did not help. With trepidation decided to tear it apart. Used the video from Gwinette Woodturners. Took less time than expected. Found that the plate that holds the eccentric arm has four screws holding it. Two were rattling around loose, the third about half way out. Tightend everything back and it purrs now. Even quieter than when new (about 1 year from ebay if you believe that).
