....
the bearing race will be hardened steel but the rest of the hub isn't therefore its seperate

That too! 

[feeutfo]

If that race was seperate to the hub, the hub (and the wheel) would fall off. Leaving the bearing on the stub axle.

The outer race is machined into the hub. Or put it another way, the hub IS the outer race.

Which side are you talking about?
the race shown in this picture HAS to be a separate seat, it'll seat right up to a shoulder machined in the hub (& presumably the same on the other side so that as you tighten the hub nut you load up the pair of bearings)

There are two races in the pic. The one you see, and one behind it. It's double sided one either side of the same central ridge.

So think of ot this way,there's the inner inboard race on the stub axle, the the ball race with plastic cage, then the hub goes on which forms one side of the double race baring complete...then the second ball race with plastic cage goes in on the race you can see. Then the outboard inner race goes in followed by the nut that squeezes the two inner races together onto the single ridge in the hub(the one you can see) there by holding the hub in place. If the central ridge was separately pressed in, the weight of the car would lever the hub off the baring.

1.Is there any reason the inside of the hub couldn't be hardened in a seperate process?
2. Can somebody show me the baring complete to be pressed in?

The shoulder is machined (or not - whichever way you look at it) into the hub 

1.Is there any reason the inside of the hub couldn't be hardened in a seperate process?

Cost. 

2. Can somebody show me the baring complete to be pressed in?

Sorry! I just bought my hub/bearing & paid someone else to fit it on the basis I was too bone idle to do it myself.

Right, so you argued earlier, which bit of the hub pictured needs to be removed? There's nothing left to remove Andy.

Still say that the bearing outers back up to a central shoulder inside the hub. If you remember back to Newent, MarksDTm was trying to 'polish' a little off the mating faces of the two inners to take up the slack in the hub as a whole - an alternative to that would be a few 'thou' shim under one of the outers.

Or buy OE

What? 
You'll be telling me it turns 360 degrees next. Maybe it's a Bury thing

I reckon the races will come out. 

The whole lot is sandwiched together by the hub nut so it can't move, that's why the wheel doesn't come off.

The races are already out.

[feeutfo]

Plus can we get the old hubs and see about fitting new bearings?

No!

[Andy B]

I'll sort you out with a large slitting disc & then you can cut one in half to see what goes where ..............

I'll send you the hub and you can waist your time as well.

I you like ............... it can be a 'project' for one of the apprentices at work

Actually I meant all 4 races. You've only got the outer races out so far.

Surely you mean the two inners  ie the two parts that butt up to each other when you tighten the hub nut
