The local tip replacer here has a tendency to get glue on the sides of my ferrule. He invariably wants to sand the sides and make it look nice and clean because, as he states, he is a perfectionist. I always have to ask him, politely, not to sand the ferrule. I don't want diameter loss over time to change the way my cue plays, and I'd rather have an ugly ferrule than have that happen. Truth be told, I'd rather have both, and every once in a while I will let him sand it clean.
The question is, should he not be letting the glue get on the side of my ferrule in the first place? I'm not even talking about right at the tip. There will be glue 1/4" or more down from the tip.
