Pipe needed for leverage on lock ring wrench

I only say "should do the job" as I've only used it once before, to tighten a lockring. Totally threaded the hub while barely applying pressure in the process. A bit too much levarage for tightening but should be just the trick for loosening.

Who uses an extension to tighten things!?? Crazy!
