Pipe needed for leverage on lock ring wrench

Put lockring spanner on. Get it in place and under lots of tension.
Hit it very hard with a spanner.

Either the thing will come off or you have to buy a new wrench.

Hit it hard with a spanner ! Hit it hard with a spanner ... who did your bike maintainence training Bodgit and Bodgit cowboy bike repairs of holloway road, you definately didn't get trained by Rolls Royce Aerospace Engineers did you.
