Does anyone have suggestions on how to get the rubber grommet to NOT scrape against the machine?? I put a metal washer in between but the washer just grinded down the metal on the machine from the friction. I dont see any other way beside that to get the machine running though. This machine is awesome but i have no idea why he designed it like this. Dale sent me a new part to replace the grinded down part but what now, just use it til this one grinds down also?? lol, any ideas??
