Ok just searched for almost an hour and damn near pulling my hair out. I want to order a set of brush's for my 55t lathe motor so if they fail I have a set on hand. I have searched and can't get any specific answers as to what brush's guys are running. I also have searched thru tower and there are like too many brush's to even think about just picking a set. So what are you guys ordering (I did see silver mentioned) for replacement brush's?
