Well yeah, big tools big mess - but all ends well.
I was most fearful of rendering the threads unusable with so much pounding. During the surgery, the empty cartridge moved only in tiny increments, and I'm sure I looked very silly re-threading the new bottom bracket over and over as I went along, lol. My "wish" was that the BB would chase the threads sufficiently - maybe I just got lucky (Mercifully both sides threaded immediately and true when all said and done).
As for 'face', I bought my daughter a new bottle of glittery blue nail polish to replenish the one I "borrowed" (after getting the appropriate authorization of course) to hide the bare metal at the ends of the shell. I probably should care more than I do about the cosmetic aspects; one would have approached the whole enterprise differently on a 'cycle that wasn't a throwaway to begin with.
