This one was fun. There was no part of this freewheel to put a tool to take it off. It had two little notches on top where it looked like a spanner would sit, but there is no way in hell you are going to get the torque you need to remove it with a spanner, so I busted out the Dremmel, cut it down to the part that was threaded onto the hub, and put that in the vice. Bada bing, it came off. Sweet!
