My father in law gave me his old B&D 8" random orbital and some it came with these wooly looking "pads" that you slip over the disc and then tie a draw string and tuck the strings under the "pad". Does anyone know where I can get some foam pads for use with FI it II and some Meg #26? (I do need foam pads for those products, right?) This may be dumb, but could I just buy some tape backed velcro and put it on the disc and then use any kind of velcro pad? TIA
