After I broke the stem, I removed the long bolt after a bit of a struggle. The stem still would not budge.
sprayed some gt85 up the headtube and around the stem/headset connect and down the stem hole where the bolt was.
Stem would not budge
Soaked stem in more gt85 overnight. tried removing stem again next day. would not budge.
Tried putting the bolt back in but leaving the top of the bolt up a little bit, so it wasn't screwed it. Hit the top of the bolt with a hammer - Hooray! I could hear the bottom of the stem rattling around in the headtube.
Stem still would not budge.
Soaked overnight in gt85.
Messed about with trying to put long thin things in the headtube to try and hammer the stem out UPwards.
Finally got quite pissed off. turned the whole bike upside down and held the frame inbwteen my legs and took a massive swing at the clamp bit of the stem...
Stem had moved a bit!
Kept hammering at the stem in an upward motion from the headtube (but still holding the frame upside down).
Fuckin rusty stem poppped out! Fuck yeh!
put the new one (donated by Geordieboy, thanks dude) with LOADS of lubrication stuff I'd bought for the job. I don't want this to happen again. Thanks everyone for the great advice, and for other people in historical threads who had suggested all the things I'd tried :)
