Hello Charles,
Congrats on the JT tandem.
Regarding the stuck eccentric.......
1.Try giving the gap between the eccentric and the bb shell a good dose of Kroll. Then with a piece of scrap hardwood begin tapping (using a mallet) the sides of the eccentric. You can try applying heat to the bb area with an electric hair dryer. That would help the Kroll do its thing. Of course you should have cranks removed by this time.
2. Using two long bolts with washers and some nuts, attach them where the bb pinch bolts are. Secure the bolts with nuts to prevent the bolt from moving (you may want to use washers to protect the paint), Thread a nut on the opposite end of the bolt, using a washer to protect the paint and unscrew the nut so that the bb is expanding. Do this on both sides (in tandem?). Tap the aluminum eccentric with a piece of hardwood/mallet combo. Use Kroll.
The last person in there probably did'nt grease all contacting surfaces or some type of electralisis has taken place between the aluminum and the steel. I faced the same issue X3 on a Jack Taylor triplet.
GOOD LUCK!

I need to move it--adjust it--and I can't figure out how to do it. There is one hole in the left side fitting that appears to be there for the purposes of adjustment, but I can't suss out how to use it. I loosened the bolts that keep the bb tight, then I tried using a punch and hammer to move the fitting, but no luck, it's solidly in there.
Any suggestions? I really need to be able to adjust the bb at this point, or we can't ride the bike.
Thanks!

Concerning Carlos Kleiber one of the greatest of all post-war conductors:
The glamour often associated with a conductor's life held no appeal for him; he preferred to stay at home in Munich. He once told Leonard Bernstein: "I want to grow in a garden. I want to have the sun. I want to eat and drink and sleep and make love and that's it."
