Do sanding belts have a shelf life? I was just outside trying to sand down the rough edges of my current project, and the belts on my trusty Bosch kept breaking at the splice. I checked that I put them on the right way etc. But one after another popped. Yet an old worn out Norton belt worked fine.
These are Klingspor belts which are two or three years old - never used, stored in my basement shop along with the Nortons of similar age. I always thought they were known as a good brand, but after tonight's performance, I don't know.
What are your thoughts?
