i ended up going to broadway bikes on friday to fix my bottom bracket - it needed a complete overhaul, and i've only worked on one-piece cranks on old three speeds before. anyhow, i'm SO glad i did because it turns out my bottom bracket is swiss threaded (?!) which i'm researching now. i definitely needed more tools than my friends have, and the expertise of the staff to not **** things up. the cranks are tight, and i learned some new stuff. also got my chanline in better shape. an excellent way to blow off work, and thank you for encouraging me to go to them and not just half-ass it with borrowed tools.
