Hi all.
As I undid the Nds plastic cup it must have seized onto the bb as it pulled out the body,leaving the ds cup in the frame
Short of destroying it how can I remove the plastic cup?
The bb is smooth as silk so I don't want to right it off just yet!
Thanks
Kes

Re:

I had this issue on a steel framed pine mountain. Addressed easily with a simple serrated kitchin knife. Saw through gently...even more gently when the blade nears the threaded shell. Mine cut through leaving no damage to the threads. Probably be even more careful if its alloy
 
Re:

It's stuck on the bb,not in the frame!
If I do destroy it I will be short one nds cup.i can't find anywhere that sells them!
Anybody know where I can get one?
Thanks
Kes
