The whole thing is rather simple. One needs the VAR tool #368. When the first two thread position cogs are off, the half moons clamp on the middle thread position. Place it in the vise, keep tightening down on the tool with the cluster body in it until the pressure is sufficient to hold the body tight while you twist the large cog off with your chainwhip. If you wish to remove the second one in, do it. Now you have a naked body. Nice. Now you should be ready to cleanse body, if needed, and start rescrewing, cogs that is, to your bodies needs and desires, for your cycling needs I might add. The trick is to find the VAR #368, or something like it. You could put the cluster in a cog holding vise, then undo the back ones, and then put on the sizes you want. Then take the cluster out, turn over and put the large cogs in the cog vise and then remove the front ones. Keep in mind you will be tightening the hell out of the opposite side when you do this because of the reverse threads. If you use this method, I suggest that you put some spacing between the cluster and cog vise to keep the cluster from cocking sideways and twisting / bending / or even cracking a tooth on a cog, while you are using tremendous force to loosen the cogs. Watch your back and fingers because you could break a chain on your whip and either fly backwards uncontrolled in your room, or forwards into the bench. OUCH! Been there, done that.
