I don't do it sloppy loose, but I don't want to need a press to put them on either. Been doing it this for 30+ years myself and my dad did the same. NEVER spun a race in a case. I don't hone bearings. I put the pinion stem or carrier in a mill or lathe and use a crank polisher, or just a length of emery cloth to take enough off to get the race on easily. This is the same way that Dewco sets up $5000 low drag centers. Good enough for them, good enough for me
