I was going from some of the things I've seen done in classes and from info in the catalog. But you are correct in that it's not really the right tool for the job. Dan Wood in Eugene, Oregon (sometimes list member I think) has a way he does "pangraphing" by hand on his web page. I don't know his page address anymore but it's quite interesting.
Thinking about chainrings made me look at an old Campy ring and compare it to a newer campy 9-speed ring. I think the new rings are a 7000 series aluminum so I'm wondering about the aluminum makeup of the older rings. Does anyone know what it was? I can tell the older rings are "softer" but make up for this with thickness. There has been some talk about chainring coating in the past but it seems the "type" of aluminum used in the past for rings, and other parts, really didn't matter. I can only think of a few ads that ever mentioned the superiorness of their aluminum over the competitors. Am I missing somthing?
