Friday night, I watched while my friend Dave finished off the rear wheel for my fixer. I did turn the spoke key a bit, but it was mainly all his work. Nice job and, hurrah!, the fixer is back on the road at long last.
Saturday, managed to undo the lock nut on the pink magenta bike head set. This had been seized solid, and I'm hoping the application of ammonia did the trick (dissolving aluminium oxide, like Sheldon says). Either that or I'm stronger than last time I tried. The plan is to use ammonia to free the quill stem too, but Jobst Brandt says it's unlikely.
