More drivetrain stuff

Last night and today I was having a heck of a time getting the derailleur adjusted properly, I tweaked the adjustment barrel all over the place, with no luck. Also my time slowed quite a bit and I seemed to be working a lot. There was also something funny going on that I couldn't identify.

When I got home this evening I put the bike on the stand and discovered that the chain was rubbing the metal cage on the top wheel, and it was completely off the bottom wheel. If put back on, it would jump off again if shifted over the full range a few times. I got some pliers and did a little metal work, and now it runs smoothly and stays put well, and also it goes to the proper gear.
