Trying to remove an Italian bottom bracket fixed cup the from a vintage Bianchi, but the little bastard doesn't want to budge. I've tried the Sheldon Brown method with the 1/2" bolt, nut and washers but it appears to have caved in the center of the cup slightly (RIP Dura Ace cup) and snapped the 1/2" bolt. And yes, I'm rotating counter clockwise to loosen.
