If you got a spare few dollars you can actually buy a hydraulic bearing puller type press used one today in my rear hubs as this saming thing happened and the come straight off without hesitation
Just a bit of advice from real mechanic, you can only weld the inside of an outer race as welding will shrink the race just enough to get it out, your short cut way makes the bearing "tighter on the hub, not a smart move
Nice work. But never spray paint on the hub surface where the disc mates. Can do the rear and sides but not the face. The layer of paint between the hub and disc can cause runout. Hub to disc bare clean metal. Then disc to wheel bare clean metal. Ensures flush fitting with out risk of runout.
I’ve used a dremel to cut a slit in the races. Its small enough to cut through and not damage the hubs at all as long as you’re reasonably careful. One theres a slit, the race will slide off pretty easy. Probably a bit faster and less likely to damage the hub than grinding a large flat spot. I was thinking too, could you have welded metal pieces on two sides of the race, support the two metal pieces with slabs, and press the hub out?
Yeah maybe. Its pretty common to do it this way and doesn't take long. It actually doesn't matter if it knicked a tiny bit anyway. Do it however you are comfortable.
