Just had the same prob at work. Trick is to support the hub on the side with the spacer still attached (an old sturmey archer 3 spd hub makes a perfect support). Then with a block of wood and a hammer tap the axle through the hub, it will draw the cartridge bearing out of the hub shell as it knocks through. Then you can hold the axle, without damaging the threaded ends, whilst turning the spacer with an 8mm key.
To refit use a socket bit to support the cart bearing in the hub, so as to stop it being knocked back out and use a socket bit or a drift the same size as the outer bearing race to knock the bearing and axle back into the hub.
Its simple persuation when you think about it.
Where did you get your 130mm spacers from, if you don't mind me asking.
