Nope, not clear enough. Really need a close up of the smallest cog of
the cluster so we can see the ring with the two holes and read the
writing on that ring.

in the second image you can just see a pair of small holes on the side
of the freewheel on the hub. is this the secret to remove the freewheel
body off the hub?

Nope, it is the secret to taking it apart and replacing the bearings and
pauls. Lots of them.

i've picked up a chain whip and can't budge the smallest cogs on the
freewheel.

A chainwhip (a second can help) unscrews the cogs off the cluster body,

does it make sense to get another and pull off the smallest

to get the others off? or does the whole freehub come off with the cogs
in it?

Yes. You need the cluster removal tool that is specific to the cluster
brand and model. It can rang from two chunky (rectangular, not small
pins) to a multi-splined device.). Take whee to LBS and see if they can
see you one.

err, good luck, it looks like you are going to need it from the
condition of that wheel.

Have you tried a google for online bicycle books?
Barnetts (sp?).

I'm pretty sure that's a screw-on cluster, not a cassette, so the whole unit unscrews from the hub in one piece. It also looks to me like a Suntour (just a guess), so it's best to take them off with the special 2-pin or 4-pin tool, like these:http://www.awcycles.co.uk/products.php?plid=m2b0s72p9119&PHPSESSID=f27a1db5a11bb0dbdc1b51136149c762

If it is a Suntour, the outside cog may unscrew on its own, so it's probably better to hook on to one of the middle cogs, although, it's my understanding that it's best to take clusters off with the small tools, as above. You might bust your chain whip

I guess you don't wanna hear this, but if you take to a shop tomorrow, they'll get it off in about 5 seconds 🙂

It's a shimano screw-on freewheel, which needs a special splined tool to
remove it. The retainer with the two holes holds the whole thing
together. Remove it and you get a floor full of small ball bearings,
springs and pawls. Ask me how I know ;-)

As you've heard, take it to the LBS and they will whip it off real
quick. What's wrong with the wheel that you want to remove the
freewheel, or do you have a better freewheel to put on it?

Ok, if you don't want to keep the freewheel, the following will do, no
special tools required.

- undo lock ring with small holes in it with a ([censored]) screwdriver (or
suitable hole punch) and hammer. It is reverse threaded, so you need to
drive it clockwise to undo.
- lift off assembly
- Watch in awe as hundreds of ball bearings topple to the ground..
remember that you were supposed to put a bucket underneath the wheel.
- Clamp the freewheel core in a bench vise or large set of multigrips.
- Undo in the normal (anticlockwise) direction. It is usually enough to
clamp the core with a vice and use the wheel for leverage.
- Throw trashed core into rubbish.
