I have been searching for this answer for a few days. So, any help would be greatly appreciated. I recently came across a 80's Bianchi frame (Japanese). I don;t know much about bike mechanics, but I thought this would be a great project for me to learn. Better to make mistakes on this, than my road bike, right? Anyway I want to get it repainted, but I have to get the bottom bracket off. However, all the tools I have looked at don't seem to match the slot pattern on mine. Can anyone post a link to the correct tool I need to remove it? I have attached a picture to help my explanation.
