I just overhauled traditional cup and cone type bottom brackets on my two C&V bikes. One was a Suntour GPX and the other was unlabeled (at least that I could tell), but from the same era (late 80s, early 90s). This is a job I'd never tackled before, but it seemed fairly straightforward, and the final adjustment was simpler than I'd expected.

The one tricky part on both frames was getting the lock-ring off. I used a Park HCW-5. This fit in the lockring slots, but very loosely, and turning the ring without skinning knuckles against the frame was quite difficult. The tool kept slipping off of the lockring, and I came close to marring it a few times. There are two problems contributing to this: 1) the tool didn't fit either lock ring very tightly, and 2) the thickness of the tool was similar to (or thinner) than the lockrings themselves.

Is there a better tool for this job? Either a tighter fit, or a thicker tool, or a wrench that engages like a traditional socket head, would make this job much more straightforward.

I realize most people today would just replace the BB with a cartridge, but servicing these wasn't all that hard, and their condition didn't seem bad for 20 year old grease and bearings. I see no good reason to ditch these BB which are perfectly functional, in exchange for the latest trend, which is why I posted this question here rather than in the mechanics forum.
