<< I could give it some wet & dry>>
I really wouldn't want to do that myself.
-As bearing tracks are supposedly precision ground and hardened.
They can however generally be removed using a little ingenuity.
Method 1
If I found I was unable to locate a drift onto the edge of the outer bearing (quite common with many bikes actually) then the way I'd do it would be to use a small piece of scrap steel of about 3/16" thickness or so, and of a size that will 'bridge' across the the stem hole from one side of the bearing track to the other, and then tack weld (stick weld) it to the face of the bearing track itself (the race itself being scrap, after all) so that it (more or less) covers the stem hole in the race, that will give you something secure to use a drift against
The offending item should then be fairly easy to remove with a couple of sharp taps with a drift, as you will be knocking it out square.
Method 2
If a piece of scrap metal of a suitable size isn't readily available to weld in, then 'tabs' of weld can be built up on opposite sides of the bearing's stem hole to locate a drift against? Just make sure you don't manage to weld the bearing race to the headstock though!
