Wonky Cassette Removal?

I am starting my new year single speed project and have already run into problems, hurrah! I am trying to remove the cassette with what I think is the correct tool: http://www.sbrsports.com/471-7646

Anyway, although the number of grooves appears correct the socket doesn't fit into the the cassette. I think the cassette may be slightly bent, picture below. Does this look bent, and if so, any idea how I can get the the thing off?

my guess is...the tool you have is for the newer type of cassetes...where the freewheel mech is a part of the hub and not the cassete. the cassete is mounted on the freehub and secured by the lockring....which you undo by the tool you have....
yours looks like old type mechanism where the freewheel is part of the cassete...to remove it you need different tool....
i guess this...

good luck bro

Take a picture of the tool you are using, because broken_77 advice is pretty sound.
It could also be inferred from the photo that the freehub/cassette combo was screwed down pissed (crossthreaded) drawing one side of the freehub closer to the axle.

The is the exact one I linked to: http://www.sbrsports.com/471-7646

It looks quite similar to the Park tool, is it not the same thing, but without the pointy bit?

I did some googling on the cassette and found: http://www.velobase.com/ViewSingleComponent.aspx?ID=5e034deb-b304-4fd4-beb3-ed597fea7e52&Enum=114

It seems it is an older cassette.

You may be right about the crossthreaded of the hub, could explain the wonk!

Oh, stupid me, didn't click the link.

That looks like one of the older style screw-on clsuters. They are different to the newer 8-9-10spd cassettes - the small cog holds them together, not a lockring.
To take yours apart you need two chain-whips, one to hold the main sprockets and one to undo the smallest sprocket (which holds the others on).

Although, looking at it again it seems to have spines.. I can't remember if my old 6spd had splines in the middle or not? Hmm..

When you say "main sprockets" do you mean the largest one?

Any of them other than the smallest. The smallest is separate from the other x sprockets.

Here's what I'm thinking of - I used to have this on my 5 and 6spd machines:

Ta hippy, I will go and purchase some more tools tomorrow. Even if it doesn't work, tools are good!

Another thought is that the locknut might be getting in the way of the spined tool? Is that possible?

This could also be true. Is the locknut that black bit with the two holes in it?

If so, can this be removed?

yes, and yes. have a go with a pin spanner i dont know how to post pics, or i would show you one

That's the lockring for the freewheel bearings - the freewheel tool is smaller than this and shouldn't be near it.
I meant the cone locknut - the one you would tighten/remove with a cone spanner on the axle itself.

ring... nut same thing, hit it with a hammer

DO NOT HIT IT WITH A HAMMER

Ta, I take it you put these in the two holes and twist to remove the lockring?

no i got confused by talking about removing the smaller cog, dont follow my segustions

Don't touch the two hole thing for now.. you'll just spill freewheel bearing everywhere.
Put it back in your bike and then use a chainwhip to try and undo the smallest cog (or use two whips).
Do you have a cone spanner? If the splined tool doesn't fit in deep enough you might have to remove that cone locknut (the skinny hex nut thing on the axle)

You guys are so fast with the replies I can't keep up!

It is as if the tool I have doesn't quite fit in the hole, i.e. as if the socket is a bit mis-shaped. It does look a little bent.

I will buy a pair of whips tomorrow and give it a crack.

I don't understand what you mean about hex nuts?

vegan: see what you've done! :P

ads: forget it for now, try the 2 whips thing (it's gonna be tight!)

they hold the wheel barrings and dust caps in place. you've got the hub, with the barrings, then dust cap, then a spacer then the hex locknut, then the axel end nuts.

i dont know if that helps, but agin i cant post pics

On closer inspection of the cassette it does appear to have a slightly different smallest cog, thus I will try the whips tomorrow after I bought a pair, thanks all.

well.....the reason why the tool i showed you and the one you have look similar is because they look the same only the diameter is different....the modern lockring is bigger the older threaded cassette you have is smaller......if you look at the line of park products you will find the same one with the pointy bit as well......and before you throw away money for 2 whips look at the park tool website for repair help/freewheel removal to find out that the only occasion you use two whips is when there is no lockring.......and your cassette clearly has it.....yeah and it shows the remover i showed you in conjuction with older shimano threaded freewheel......which is the same system you have.......but i only guess:-)

spill bearing???? it says on the thing sealed mechanism.....sounds like cartridge to me........so no spilling unless you are planning to stab to poor freewheel,which you may as well do out of anger after you just spent money for two whips you had just bought...or whip yourself with them..as a proper christian........but i only guess.....

Again thanks for all the input I will buy tools tomorrow and let you know how I get on. Plus a list of the injuries I will no doubt sustain while trying to hulk hogan this thing off my wheel! Thanks guys!
