Easy way to install sanding discs

[Tmate]

This is an old trick, but some may not be aware of it. Sanding discs are almost impossible to install on a bench sander without the glue sticking to the plate while you are trying to slide it down.

The answer is to lay a rule on the film side and lightly cut half the film off. Then insert the half of the disc with the film still intact. Stick the glued side to the wheel and then turn it to remove the other side of the film.

I do something similar, rather than cut the film ( paper in my case ) I peel half and fold with a sharp crease then do as you did.
