Hmmmmm, amateur night. Okay, fair enough. The "rollers" are called "knuckles", and yes they supposed to be round. There is a popular remedial repair that I have recently become a big fan of, that being to weave yarn into the core felt to bolster it up and make it round again, (or at least somewhat round). You can lightly sand the leather to remove much of the grooving. Regulation will be required. That of course is another subject. I'm sure many members of this list are just dying to hop in and continue this discussion.
