Helicomatic freewheel stuck on.

As title. Undone the lockring using the bottle opener, tried to lift the freewheel off... Nothing budging.

I thought you only need the bottle opener :?: Got me well confused. Sheldon Brown's no help here.

there's a slight rifling on the splines, so they don't lift straight up like a standard Shimano or Suntour cassette. may need to apply a bit of spray lube or anti-sieze in case there's rust involved

Any attempt to turn while pulling just makes the freewheel err... freewheel.

Drowned it in oil, all that did was make it spin smoother.

 

[watcyc]

have you tried a flat blade screwdriver between the large cog and the hub body?

 

[Ian Raleigh]

Never mind shag! Use one of these if all else fails.

 

[watcyc]

and could be an obvious question, did you remove the lockring or just loosen it?

 

[Bats]

Removed it, on account of I know what a lockring is.

No attempt to prize or knock the freewheel off has worked.

Are you all 100% sure that after the lockring is removed, the freewheel isn't unscrewed with a tool? It looks like it is, but I can't find any information on it.

Helicomatic free wheels use a 45° ish helix to hold the free wheel on (harder you pedal, tighter it gets).
Might just be a matter of getting a punch on the back of it (the non-free wheel bit, obviously) and giving it a tap in the right direction.
There's no chance of notching the carrier, so it'll probably just be slightly rusty, or dried grease.
