Success! Got the BB cup out before heading off to work. I had the correct spanner but previous attempts had resulted in it slipping an taking my knuckles out.
I realised I had to clamp the spanner onto the BB to stop it slipping off sideways. I got my trusty headset press (well threaded bar with huge thick washers and nuts on) and did this. Wouldnt shift by hand at first so I held the frame upright with the rear dropouts on the floor and used my foot to lever it. A big crack and the corrosion was broken and it started to wind out.
Pic of set-up:
No damage I think, all ok!! Didn't have time to take it all the way out but did a couple of turns and it was coming out ok.
Big relief as those spanner flats on the cup aren't very big and I didn't want to have to cut it out after rounding the flats off.
Phew!!
