One of the rollers seems to roll more freely than the others. I can give it a push, and it will roll a little but on it’s own. The others, I can move them all fine, but the moment I stop pushing, they stop moving. How easily should they move on the conduit when not hooked to belts and stuff? Should it be stiff movement? I played around the bolts to see how much losening or tightening them affected it, and it didn’t seem to make any difference.
Keep them as loose as possible, they will settle and wear in. Don’t worry about how smooth or sticky they are if they are all the way loose.
