I have made my own Scotch Bright buffing pads for my Dremel for years using the mini-arbor for the tiny cut off wheels. I just cut circles from the pad I want to use & push the screw through the center with a washer on either side. I usually use a double thickness. It doesn't matter if they are exact because they quickly become rounded from wear. I've been known to use them until they've worn down to the washers like the reddish ones in the pictures.
I have done this for years & is one of my most frequent Dremel uses.
