Removing sprockets

[petehouk]

Hi everyone. I am trying to get the sprockets off of a 5 speed freewheel. I got the freewheel off the wheel but now I can't get the cogs off the freewheel. This freewheel came off of a 64 Collegiate. I got the three smallest cogs off but now I can't get the other two off. Is there some trick here? Backwards thread or spline or something? Thanks

Try using 2 chainwhips?

I used the chain whips to get the first three smallest off. But I can't get the two largest off. I have been holding one and turning the other. Do I need to hold something else while I turn these? Do I need to hold the body of the freewheel or something?
