I think you guys are making this harder than necessary.  Remove the studs &
the seal, then mount the hub on the spindle and pull the bearings up to no
clearance.  Spin the hub and mark with chalk to find the high spot.
Carefully file away the chalk using a machinist's (flat) file, then repeat
as necessary.

Yes, it will take some time, but no worse than having to machine mandrels
and whatnot, plus can be even more accurate (tho for best accuracy, a dial
indicator would work better than chalk).

To do it on a lathe, put in the inner races then mount the hub between
centers.  Even though the taper of the centers won't match the taper of the
races, it should locate the hub very well.

But no die grinder in either case !
