Looking for some help on cassette removal. I have an old Dawes mountain bike and am looking to remove the cassette. I've read through the Park Tool tutorial and looked at the different tools. I don't believe any of them could be used in my instance though. I have what looks like a single speed locking ring - external notches - although a bit larger at 46.5mm in diameter. The ring has 8 notches and having cleaned away the muck that was hiding the manufacturer's name and model, it's a Shimano MF-HG40 7 Speed Megarange Freewheel. I just don't see how the often quoted Park FR-1 would do the job.
Which cassette removal tool?

First of all
to the forum!
A freewheel is different to a cassette. You need a freewheel removal tool, not a cassette tool, so just be careful you're not mixing the two up. You will also not need a chain whip.
Simply insert the freewheel tool and unscrew anti-clockwise. It will be on tight, so you'll either need a long lever, or put the tool in a bench mounted vice and use the wheel itself as a lever.
A picture of the freewheel on the wheel, with the wheel off the bike, may be useful - But I suspect that the FR-1 will work fine from the model description you have given.

Did a bit of searching and I believe I've found your freewheel:
The tool slots in to the centre splines, near where the axle and locknut will be. Ignore the part which looks like a lockring. The video below may help you in understanding how it works:

Hope that helps!

You may need a big extension bar to get the old freewheel off. The pedalling action tightens them up, and n years of grime can make them a right pig to shift. Not for now't does my toolkit include an 8 ft scaffold pole.
That is impressive leverage (although more impressive would be the corresponding toolbox). Only used to piddly little allen key extensions, so I'm hoping the second method of captain at ship's wheel is going to work. Tool is ordered, I'll keep you posted (on how many expletives are needed to work the thing loose).
