I agree with this post. Place the key in the vice using as little depth as needed. The splines on the key should still engage enough of the freewheel to loosen it.
If that doesn't get it, use a couple of chain whips and unscrew the outer cogs. That should give you the room you need to use the key in a vice.
And yes, good luck with that!
The worst freewheel removal I ever did, was when I had to disassemble the whole freewheel. I mean I unscrewed the lock ring and let all those little bearings diperse themselves all over the shop. I then clamped the inner freewheel race in the vice. It still took 3 of us turning the wheel before it broke loose!
And of course when it did, we all ended up in a pile on the floor!
Hope you don't have to go THAT far! Reassembling a freewheel is a bear!
