Why does the sand belt on my sander keep snapping?
Question:Im using a belt sander to sand down the staircase and the skirting boards in my hallway, ive bought new sanding belts and they are the correct size for the sander, but everytime I begin sanding, after a couple of seconds the belts snap, ive spent a fortune replacing them and they all keep doing the same thing, why?
Answers:
i suspect the rollers are out of alignment.could be they are just wore out.this would cause the belt to run to one side and to snag on something .another possibilty is you are running the belt too loose or too tight.is this a rental machine? if it is id take it back and have them show you how to change and adjust the belt.
Its a common problem.
Does your belt sander have an adjuster on it?
If so ease it back a little and retighten.
Are the sand belts of a poorer quality than that recommended by the manufacturer?
Suggest also that you present with the offending item at the shop you bought it in an demand an answer to this problem.
As already mentioned Alignment or even sharp edges on rollers or tension.
Some belts have a "direction" arrow inside. The direction the belt moves must match the arrows or it can be damaged. I believe it has something to do with the way the belt is glued together.
