UN70 problems

[scottproonly]

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:

You can but a basic complete shimano bb from chain reactions for a tenner. Cant buy the cups alone

Re:

Are you saying buy a UN26 just for the cup or write the UN70 off?

Re:

Why do you want to remove the cup? Should insert fine as it is?

Re:

The trouble is that when I fit the ds cup it pushes the bb even further into the nds cup!
Arrrrrrgh!
