Wheel Bearings!

Hi All,
I have a set of alloy hubs that i am having a hell of a time getting the wheel bearing cups into. Saying that, i have managed to get the small cup in OK, but the larger one is in half way and no more...
Yes, i have a F#$%&* Big Hammer that has destoyed 4 punches so i was wondering if someone has had these pressed in before? Do normal tyre places like Bob Jane do this? Any help appreciated...
Cheers,
Mick.
