I never bothered with lockring tools for the cone on these BBs.
Adjust it close by pushing it around with a punch. Tightening the lockout will push the cone inward because of thread slop.
After a few tries you'll get a sense of touch about this. If it ends up loose, back off, adjust in a bit, and try again. OTOH, if it ends up a hair tight, use the punch to force the cone back against the lockout.
If you do three of these, you'll be nailing it every time afterwards.
