Thanks for all the bananas
Reviving an old thread because I'm stuck too. What kind of lube should I leave on the lock ring overnight to eventually loosen it?

Yeah I have the right tools, I even slipped a seat post over an adjustable spanner but still no joy! Towels over the chain whip tool too (which annoyingly has a spanner tool at the end of it!).You got a chain whip?
The same solution I always recommend...pure brute force, wisely applied. Ok so not the hammer. Just load up the tools something like 2:45 and 9:45, then push down hard and constant with all that big hunk of man you're carrying around until it goes. You may want to get another chunk of man flesh and do it together. You may need to slip an old seat post on the end of each tool to extend them. But eventually you should outweigh the bolts stubbornness. With two of you you can pull or push away from each other. Watch out for awkward collisions.
I removed a SRAM crank for a friend a few days ago. The bolt advised spec to 50nm, which is a difficult amount of force to apply with a standard Allen key. I put the trusty old seat post extension on there and (I don't know why as this guy weighs maybe 50kg) got my buddy to put all his weight on the relevant pedal. He rose off the ground a little bit before the bolt have way! I suspect the shop may have just guessed what 50nm is. Anyway it was the constant force of him on the pedal and me on the tool both just pushing down until it popped. No jerking or bouncing or hammering or trying to force it. Just heavy constant pressure.
Or get out the hammer and bash that tight fucker off!!!
Yep that'll do it, the cassette will either run screaming from the room as soon as it sees it or it'll be yours for life.
I have one of these -If you have one of those locking tools that you put in a shifter, then you don't have right tools for the job...
I don't have a vice but I also haven't tried squeezing together like this photo.If you have a vice try placing the lock ring spanner in the vice. I know you have computer hands but also have you tried squeezing the spanners together?

They can be rather tight and worse if someone has cross threaded it beforehand. I would apply anti seize on the thread, especially if you live in a coastal town.I don't have a vice but I also haven't tried squeezing together like this photo.
The best ones are like that but have a 1/2" square drive socket recess in the end. A 18“ breaker bar and decent chain whip is usually enough to show it who's boss.I have one of these -

Get one! Best way to tackle it.I don't have a vice....
Ok fuck it, it's hammer time!
STOP! Fuckwit time!
You fucking monster! Go to the naughty corner.2- use an impact gun. I've got a massive 1/2 drive DeWalt impact gun meant for wheel nuts. Have used this on stubborn lockrings that have broken chain whips and has worked in seconds.

As I thought...you don't have the right tool. Personal perspective, but there is too much chance of your shifter slipping off that under the type of pressure you need to make this work for me to do it, but...life's too short not to go big.I have one of these -
