I'm going to need some rollers. I was thinking of just getting some 1/2" stainless rod and cutting it down to size to replace all the rollers. So far, I've got one that's really worn with a groove in it and doesn't roll very smoothly and 2 others that are worn a little. They roll a little better but still not smooth.
Stainless rod might not be a bad idea?! I hadn't thought of that. I do have a few though so find out how many you actually need and I'll check and see just what I have here
