How can I do this without the "proper" tool? I've tried to find a guide online but can't find one anywhere.
Do you mean the bearing seal on you BB?
Yep
I failed miserably when I tried replacing the bearings in mine.
Bought a new Hope instead.
So you have the top hat shim out and now you can see the bearing, then just use a pin get it behind the seal and pop it off. Now if you want to get the bearing out they are difficult to do without the right tool crc used to do them have a look in the tool section.
I took mine apart with a hammer and a drift - usual thing of heating the cups in hot water and freezing the bearings for reassembly.
However the top hats are fragile - you just have to pull them off.
Seals came off the bearings with a scalpel blade
Sorry... was a bit confused there. I mean the top hat. I've managed to partially crack one by levering it gently with a scalpel but still couldn't get it off.
Can you get spare tophats from someone like Chris King?
Don't know if you can get spare top hats but you can get a bearing kit from BETD they do a bearing and seal kit plus the bearings don't need the top hat spacer as they are the same size as the hope ones and fit directly on to the crank shaft.

replacement top hats /\
I have seen the betd bearings Enduro do them as well 20 quid they are 24mm so direct fit on the axle
Spock thanks for that link ,been looking for a while as it's dead easy to get the bearings out but the tophats crack easily.
So... how do I get the top hat out?
very carefully with a Stanley knife , very carefully
Well I tried levering the cover off and only succeeded in cracking it a bit. Is there somewhere better to lever or some other trick?
