Can't seem to get enough leverage to unlock the lock ring. Any advice?

I assume you're using a chain whip- without it I don't think you could get any leverage. Other than that, the only solution is a longer wrench. It helps to hold things vertically so that you can use your weight to push down on the wrench, but even then you won't be able to do it with a short wrench.

Yes using a chain whip and a pretty good size crescent wrench. This is the first time to remove the cassettes as I bot the bike used last year.
What about a vice?Alex-in-Evanston

If you've got one, can't you just secure the bb tool in there and turn the wheel like you're driving a bus?

I've got no vice, so I use the chain whip and 15 inch crescent wrench.

Anytime you use power tools on a bicycle, it's a pretty good sign that something has been screwed up. I assume you have already made sure you are pushing in the correct direction on your chain whip and lock ring remover. Always check the simple stuff before you reach for the heavy artillery.

I once had a cassette lockring that was on so tight that I was afraid I was going to break my chain whip. I suspect that it was the wrong lockring for the cassette. Eventually I used my Dremel tool to cut enough of the lock ring away that I could get it loose.
WD-40 overnight?? Its intended use....TFerguson

Spray it with WD-40. It may penetrate into the threads overnight.
Put the cassette tool in the splines and use the skewer to hold it in.
Put the chain tool on so that you would be "tightening" the cassette.
Put the cresent wrench on the cassette tool good and tight and position it so that both handles are about an inch apart. Squueze the handles together with both hands.
If that fails, you could try giving the wrench a good wrap with a hammer.

the handles together to break it free.
using the outer cogs, like the second or third cog, keeps the handles aligned next to each other.

I suppose you could some rope and a dowel as a 'turniqutte' to squeeze the handles together as well.
