If you are tired of unscrewing the RCBA Vibrator bowl wing nut, about three inches long, I have a solution. Take a piece of thick walled tubing, steel of Aluminum, cut a slot in the end of it about 3/4" long and 1/4" wide along the tube vertically. Chuck the tube into a Battery powered drill and wala, you can put the drill into reverse and off comes the wing nut, just put the drill in forward and run the wing nut down, but not until it makes contact with the plastic bowl, it could crack the bowl, Just finger tighten to finger tight after that. Save time when emptying bowl of media to extract cases. Good Luck.
