Cheers for that, Jon.

Yep, deduced that from Mick's post.

I'll have to speak to the chap again and ask, but I'm guessing that the threaded part will have got damaged when he removed it (not sure how he got it out).

I probably won't get to talk to him until after the weekend, unless one of the other chaps at work can get a message to him or his wife.

And I'll ask him to look in on the thread.

Mentioned the April Bash, too, which he seemed to like the idea of.
