My old bike has a freewheel that takes a 4-prong SunTour extractor. I tried it, and the result was that 3 of the 4 prongs on the freewheel broke off. I googled, and followed Sheldon Brown's advice and disassembled the freewheel. My problem now is that the freewheel core is totall smooth, and there is nothing for the bench vise to grip onto. Am seeking advice on how to remove the thing, as I have to replace a broken spoke (and have to replace the freewheel anyway). I've gotten some suggestions as using penetrating rust-remover solvents, but there is no rust. The thing is just torqued on really tight. I would appreciate any help.

get a Dremel and a cutter and carefully cut the thing apart. If you are careful, you won't hurt the hub threads.
