Thank you, Sparky! That would make sense because one rolls really, really well, and the other one rolls, but it sounds like it has sand in it when I turn it. I purchased them from a gentleman who had rebuilt them and I'm not sure how to remove them because they're riveted on. I feel like I could smooth out the middle of the button/the little bar that it goes on, but I'm not sure how to take that portion apart.
