You also need to break the chain... Well, although you don't HAVE to, but it'll make it a lot easier.
I made my own tool for the nut on the side using a large pipe that happened to be the right diameter, and grinding the sides until I had four pins. But it worked less than perfectly as it kept sliding, so I made a rig for it... A pain in the ass, in other words. You might try an autoparts store as some cars and trucks use them for the CV joints. All the people working parts here were total boneheads though, so I was stuck on my own.
If you have $150 to spare, just get the socket set.
