@Batman But a nice surprise. It's not that old really. I think it means he actually did what you suggested and was happy with it. IMO it's better to have a considered acceptance like that then when someone accepts the first halfway reasonable answer within hours. Deters others from making the effort to answer.
You may be able to use a two-pin adjustable BB tool. That search pulls up a lot of images of the tool I'm thinking of, and they're available right down to $5 or so
(from my comment since we haven't got a better answer)
that was accepted recently, which is kinda odd because it's IMO a kludge even though it's also very likely the correct approach. I mean, the tool is sold for the purpose. It's that that IME it's very easy to bent those tools to uselessness if the BB is even a little bit stuck. The solid-metal version is better, albeit 5x the price.
@andy256 today is a negative LOC day - I'm chopping out half the work I've done in the last two-three months because we have changed our approach. It's a good decision, but it's still not a great feeling.
