Have ya thought of this??
Locate an old variable speed polisher/sander and use your wire wheels on that.
I have an old polisher that I did just that to.
Those grinders spin pretty fast and will wake yer hiney right up when it catches the cord
. I have also managed to grind divots into various parts of my anatomy----this generally has some sort of painful stoopid idiot
lesson attatched to it.
