Mini stems were all alloy wern't they ? If you can get the bolt out and the wedge out of the bottom you might be able to knock out if its really stuck. A piece of wood might be ok and not damage anything. Be careful when you support the frame and forks so nothing gets damaged though.

I don't know if anyone else can think of a good way but if all else fails it might be best to cut the stem so you can get the forks off and then get the bit left in the steerer tube macjined out.

As suggested give it a good soaking, WD40, Diesel etc. Leave it stood upside down filled up and see if that works.

just whipped diesel in it for an hour see if that works

Might need longer than that if it's gone all white and crusty. Hope you can save it.

All good. Fired a load of WD 40 and clamped the stem in the vice and just hept turning a small bit back and forth and eventually it came out. was sticking all the way to the end. Took me about 2 hours in total but the stem is in good shape and so are the forks. Glad i didnt try and force it and break somthing

Thanks for the advice though
