Actually, I'm slipping the bolt. I removed all the washers, but one on each side of the cup. This leaves me working very close to the stays. One slip has already left me with a bruised thumb (which exhausted my repertoire of cursing!).

I also have visions of the bolt breaking, and then being unable to get it off the d*mn cup.

Without a proper stand, I actually fear more that I will lose control of the frame and bash the headtube or such into/onto the concrete floor. This would be disastrous.

So, another round of soaking in the loosy juice for the overnight. Then off to make the rounds of appropriate shops in the a.m. I think that it's not so much beyond me as it is beyond what tools/equipment I have to hand. Give me a vise, and any of the suggested breaker bars, etc., and I think I'd have this. I just don't have such available where bike & I are at. sigh.

Many thanks to each of you.
