thats all very well if the lugs etc on the wheel are still intact, my tuff wheel i have just dyed had been beaten to death by some 10yr old hoping to get the thing off and there was nothing to fit a tool too, i ended up removing the centre collar with a punch and grinding the freewheel centre in 3 places and then opening the grinds with a chisel until it came off , go steady though if you need to do it this way...
