I just tried the c-clamp/socket trick with a heavier duty c-clamp and the c-clamp shaft/threaded area started bending and canting off sideways. Worked a week ago on a different bike, but the cotter I tried it on this weekend wouldn't budge. I'm now in the market for a proper press. And in the mean time I'll be taking the bike out to the garage and attacking the cotters with the heavy duty plumber's vise bolted to a portable stump. If that don't work then Pinky is near by ( "Pinky" is a 30+Lb sledge hammer that the previous owner of our house had left behind and which he had painted said sledge hammer pink).
As to getting to 50 posts, start a thread in the Road forum about how you prefer the ride of your vintage bike over your newer bike and state that you will defend that position. Next, jump to the 50+ forum and start a thread about how your dog likes to eat pie, anything pie related will generate discussion there. Then go to that other section who's name must not be spoken and ask why you should signal lane changes and that you think Forester is otherwise always right. We'll see you in about six months and 900 posts from now if you follow these suggestions.
