Tom and the gang,
The 5 mm allen in the vise sounded good but for professional problems (as you have) you need professional strength solutions.
You need a good "easy out"... A reverse spiraled one sort of like a drill bit or the sharper square tapered sharp edged one that cuts (best for this) INTO THE OFFENDING PARTS! Hammer or tap the easy out into the frame side of the offending chainwheel bolt. Then clamp the "easy out" shoulder in to a big vise (remove the crank first if you please). Insert the allen key (5 mm) into the 5 mm hole on the outside of the crank. Use a cheater bar or tube on the allen key and turn the allen key counter clockwise and remove the chainwheel bolt or break it in half. Either way success is within your grasp.
