Yes well that's your issue. Just purchase another cork lining and glue it in with 5 Minute Araldite as this will give you time to maneuver it into place and won't ever let go again.

Not sure why you'd be replacing that spring as I can't see that being necessary.

I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
