I soaked my seat tube half way up to the top with ammonia. Most of it stayed in even though the SR seatpost was cracked and repaired temporarily with duct tape and electrical tape. I poured off the ammonia this morning, and clamped the faces of the bottom bracket into the soft wood of my bench vise. I got a good grip on the seat post with my large vise grip and wrestled with it for a minute or so. Success, or so I thought, as the seat post started to revolve out. The only problem was that the crack had migrated down into the aluminum casting and the whole seat post broke off about an inch and a half below the top of the seat lug. Now, I guess the only options are to saw several cuts into the seat post from the inside with a hack saw and hope that the thing just falls apart (a good chance I bet especially if I soak in more ammonia after the cuts are made). Another option is to send it out to have another Columbus tube brazed in... (a good option if anyone would even know which Columbus tube it needs.
The fault here, I believe is not my own. First, the dealer used only penetrating oil, which everyone said has no effect on aluminum oxide. Afterwards he used force, but because the post was still oxidized, the effect was to crack the seatpost. The second fault was Campagnolo, who cast this particular seatpost unevenly. The width of the aluminum walls were so obviously uneven. One part of the wall was nearly double the width of another part 360 degrees around, and the crack happened at the thin part. This seatpost could never stand up to a strong twisting action. If it had been properly cast this post would be out now, in its entirety.
Garth Libre in Miami Shores, about to go with the wife and kid to the easter egg hunt and leave this nightmare for a time when I am more encouraged.
