I know this has been talked about over and over , but my Google search box is not working so please bear with me . I replaced my last vibrating tumbler with a cheap one a Niagara media falls # sr787 it looks like the Lyman and has 4 screws holding the motor in place . I have already ordered a replacement but has anyone found a replacement motor that holds up . I have been overloading this cheap tumbler for a year so I don't think it is the tumblers fought .
