Well, mostly success. The drive side came out fine, but the other pin deformed a bit before popping loose. I saved it by knocking it back in line, rethreading the post to 7x1mm, and then tapping a nut to match.
Here's the spindle.
Note the lack of wear! The bottom bracket area inside was like new, just old hard grease. It's all back together and ready to go.
What is that tool you used to remove the cottered pin with? Is that a tool specifically made for the cotter pin? Something you came up with yourself? Cnc machine? I've only removed one cottered crankset and it involved a hammer and a strategically placed brick. I got it removed but the plan was never to reinstall. Thankfully I didn't need to worry about the end condition.
