Hi @Tootyred thanks for replying and taking time to explain the situation in such an intelligible way. Sorry i've not replied to the last few posts. I've thought i should wait for the hub so not to waste anyone else's time on this. Finally bought and received a beautiful DX hub with the old style barrel. I've managed to fit the cassette on with 2x 1mm spacers (leaving off the rear thicker spacer) and the cassette and 2x loose cogs all feel tight now and correctly spaced.Its really is as simple as @FluffyChicken said in his first utterance! All you need to complete the task is a spacer, put on the freehub first.....then put on the cassette.
Unless you want 8 speed or more, there us little point changing the roughly 30mm 7 speed freehub out for a 35mm longer one for 8 + speed......as you will just need more spacers to mount your cassette.
If you ask in the wanted section, im sure somebody will have a 1mm washer....
The reason there is a problem, which may help you understand the solution, comes from the way the 11 vs the 12 bottom cogs are cut where they interface. 12s goes right onto the freehub splines, but an 11 does not.....it has a rim on it.....hence needing the washer to make up the lost space so you can clamp the stack down.
Also , more "modern" hubs have a slight cut away on the edge of the splines which allows 11 speed to engage further onto the freehub.
I've hand tightened the locking ring on, but it feels like it has only clamped down into one and half of the threads. But i have just realised i don't have the lock ring tool why the hell did i not think about this when i received the cassette and saw the lock ring. Could you please clarify this is part i need:

Also it says 40N.m on the ring, so i'm presuming i will also need to buy a torx wrench as well, because i don't have one of these either?
Once i get the lock ring tool, do you know how many full turns of the lock ring i should be able to do, so i can check properly seated / fixed in to the right amount?
Actually i could probably check this by attaching the lock ring with with no cassette on. And seeing how many turns till it hits the barrel.
Because this will tell me if i need to change the barrel to the newer style where there is a bevelled edge so i can secure the 11T lock ring on to the correct amount of turns.
The one thing i don't understand surely 11T cogs were around before they changed the barrels to the newer bevelled edge type?
Or did 11T cogs come out way later on?
Thanks again to anyone that replies
