help with angle iron's

[dbreeze225]

hey guys so i went to look for my angle grinder (wells dads ..he said i could put a pad on that) well i cant find it what i did find is a buffer but the way its set up is that there is a buffer pad that fits over the plastic piece where it mounts and the "face" of the pad is what contacts the metal not the side of the pad wich is what i think your talking about is there any way i can do it with this....or i think what might be better is i have a stationary bench grinder curently has a grinding stone on one side and a wire brush wheel on the other i am not positive but think i could take the stone off and put a pad (wheel) in its place do you think this will work????
