Re:
thanks for the advice, will do this
will not be damaging the forks for sure!
the wedge is free, but still in there. i have replaced the binder bolt and tighted it up enough to stop the plus gas running out the top of the stem
would it be a better idea to somehow try to remove the wedge from the bottom of the forks and bung the hole and then fill with oil?
i will be sending this off to Jacksons or Argos for a refinish, so if it doesn't come out then i will ask them to help.
I have also managed to track down a very similar stem as a back up, if this one has to be sacrificed in the end.
