That's probably why the belts were sold as surplus in the first place - long past their "use-by" dateIn your search of those millions of videos, did you ever find a process that works for repairing belts that are brand new but which have non-functional splices (i.e. that break)? I've tried hide glue, super strong fiber tape, layers of this and that, etc... But everything seems to break after not all that much time. Unfortunately, I bought a bunch of surplus belts, so I would really like to use those.
In my experience, it's not advisable to re-join belts purely due to safety - unless you are using them on a belt grinder with speed control turned all the way down... and then you might as well just hand sand. A belt that's running at optimum grinding speed can cause quite bad injuries when it breaks, and can even result in blindness if the tip hits your eye.
Another reason for not re-joining belts is that the "bump" created by the DIY joint is invariably thicker than that of the original belt, and the vibration caused by this leads to inaccurate grinding, and even faster wearing-out of the newly made splice.
Best to use them as hand-sanding belts as stated by BaronJ above.
