Re: Stamping Serial Numbers
Ya just have to show the numbers and letters who's boss.
I use a brass hammer and systematically knock on the heads several times while rocking back and forth (the numbers and letters, note.)

You're not alone, I'm afraid we've all been there (at least me)
Just get some old spare bsa threaded cups to fit on the shell while you smash all your inner demons over the damn punches without even the slightest remorse of deforming the bb shell.
Re: Stamping Serial Numbers
Michael,
Have you considered machining a nice brass plate, stamping your serial number, and then silver soldering it to the bottom bracket?
This could then be masked off for a very nice finishing touch on the bottom of the frame.
