A club I play at from time to time just had there table recovered.. I watched the guys physically bang the rails heavily with a hammer before applying the felt.. Ever since then the rails have been far from flat...They have bumps all throughout them.. The mechanic told me that the bumps would come out in due time..Im just curious if this is the way one would fix the rails.. I have also heard that there is a tool for banging the rails..Any information supplied would be appreciated. thanks in advance
