>>1902007>Do people actually use headset cup-esque tools in hubs?I don't actually know. I knew you could remove cups and bearings but I never had to do it to my bikes yet so I never looked further into it. I was just guessing that they come in all sorts of different sizes outside of uses on bikes.
>what do you mean by 'stripping the shell inset'? 'Galling' is more appropriate.
>hammering on a diy drift that seats around the edges of the cupYou could try making a diy press with some thick washers, nuts and a threaded rod.
Anyway, looking further into it; you could use an expanding type bearing puller like picrel, they're apparently also called blind bearing pullers.
