The benefits of anti seize compound

So I recently offered a basic service with new cables thrown in, as  a raffle prize at a fund raising event at my daughters school.  The winner contacted me to book his bike in and was very pleased to have won as he wanted to start using his bike to cycle to work. The bike in question a Dawes Road bike built from reynolds 531 tubing seemed in reasonable condition although it hadn't been looked at for some time and following an inspection I recommended some additional work to bring it up to a road worthy standard.
The first item on the list was the bottom bracket with very worn bearings, so I began to attempt to remove the worn part.
Oh dear it was well and truly seized, after overnight soaking in some special home brewed penetrating oil and some additional leverage applied with a persuader ( my trusty piece of scaffold tubing) I managed to remove the offending item.
The photos below shows what happens when you don't use enough anti seize compound when fitting a BB and there is no drain hole in the BB shell to allow any moisture in the frame to drain away.
the last 2 are of the shell all clean and re-cut threads ready for its new axle.



Oh dear thats not good




Ah now thats better, nice and clean
