My NS Cleveland has an E-string tuner that's binding for some reason. I thought it might be the string wrappings being forced into the pegbox sides, but it happens with no string installed as well. I've tried lubricating the gear with candle wax, as recommended by something I read but it didn't help. None of the others are like this. It's gotten hard enough to turn that I broke 2 string winders installing a new set of strings last weekend... Anyone have any ideas or recommendations?
