BTW, GOOD idea to use a press and not hammer the cups but if you don't have $$ for a proper tool you can make a cheap but effective substitute with a length of all-thread (threaded rod) and a stack of washers and some nuts, see Sheldon Brown's site for pictures, Slightly clumsy to use but very much an improvement over hammer/blocks of wood!
Ahhh this is sadly the case. The 600 crown race i pulled off is loose on the Diamant fork crown. Why is everything slightly different lol. There are a couple of shops i can check that might have it.
And yeah, I will make that press like you suggest. I made the sheldon tool for removing the bottom bracket fixed cup on this bike and was very happy with it.

you can take good care in trimming the material and setting everything up only to have to material get between a race or cup and its seat during the pressing process
if this occurs it affects the operation of the headset as parallelism of the fittings will be off...

Good point. I do not think I will have to shim the cup. The 600 cup should press in well. I tried for a minute to shim the loose crown race I have now, but realised the shim slipping down would be quite hard to avoid. Maybe having the shim protrude up the fork steerer and clamping it with a hose clamp before pressing the race down onto it. The whole shimming business is really best avoided I think. I might revisit the loctite suggested above for the crown race if i cannot find one the correct size for the crown, and the bearings. Iunno.
