Here's a picture of the bottom bracket:
This should give folks an idea of why I need the grinding paste. If you look at the left hand parts you'll see corrosion and some kind of leftover adhesive. When you look at the right hand side and right hand cup notice that most all of that has been carefully removed.
It looks like half of this bottom bracket came new with the adjustable cup semi-permanently affixed to the body of the bottom bracket. Or did the former owner just glue the thing in place? I'm a little baffled.
Tell me what you think.
