Expanding metal rings?
I don't think so, if you measured your rings od at room temp then heated them up a 100 Deg. it would have grown maybe a couple tenths. IMO the problem is the wood it is always shrinking and expanding due to climate changes and the metal doesn't. People should consider this factor when choosing where they purchase a cue. If you live in a dry climate and you buy a cue from a maker who lives in a moist one, the cue is going to shrink. That cue maker has probably let his wood acclimatize to his climate not yours( I am not saying everybody does this but the majority do). To me this is a good reason to support your local guy, not as many problems due to shrinkage or expantion.
