Thread: Sanding Belt Help Please.

Hi All,

I have a 4"X36" belt sander with a 1HP motor. I've used both Norton and Gator Power brand belts. My problem is, both brands get a bubble in them very shortly after use. This only happend to my 120 grit belts. The 80's don't deform.I am using light pressure sanding scale blanks smooth. Is there something I can do to prevent this from happening, or is there a different brand of belts that won't deform like this? I would be greatfull for any assistance. The bubble is making it impossible to sand the blanks flat and evenly. Needless to say it is very frustrating. Thanks in advance, Don.
