Yesterday I had this episode with some 3M Trizact and Norton Norax structured abrasive belts. Less then 3 minutes of use and separation. Granted some are a bit older so the adhesive has deteriorated over time. OTOH there is a belt dated back in '06 that has worn down that is used for polishing and that splice joint is solid. Pretty unhappy to blow through these new belts and some I flexed the joint to see it lift up easily so about 3 in this group have not even touched metal.
Seems that of what has had separation are the cloth backed belts. What are your experiences among belts that the joint splice fails?
